Key Points

• Cholera toxin is an enterotoxin secreted by the bacterium Vibrio cholerae, which is unusual in having two circular chromosomes rather than one.
• Genes for cholera toxin are present on the integrated phage genome, CTX.
• The cholera toxin is an oligomeric complex made up of six protein subunits: a single copy of the A-subunit and five copies of the B-subunit.
• The A-subunit has catalytic property that ADP-ribosylates G-proteins.
• The pentameric protein binds to the ganglioside GM1 present on the surface of the intestinal epithelium.
• The A-subunit ribosylates the Arg residue of the a-subunit of Gs protein.
• ADP ribose is provided by the intracellular NAD.
• This ADP ribosylation alters the A-subunit so that it can no longer hydrolyze its bound GTP, causing it to remain in an active state that stimulates adenylyl cyclase indefinitely.
• The resulting prolonged elevation in cyclic AMP levels within intestinal epithelial cells causes activation of PKA.
• PKA phosphorylates the CFTR and Nat-H exchanger present in the intestinal epithelial cells.
• This causes a large efflux of chloride and sodium ion and water into the gut, thereby causing the severe diarrhea that characterizes cholera.

Explanation:

• Prolonged elevation in cyclic AMP levels within intestinal epithelial cells causes activation of PKA.
• PKA phosphorylates the CFTR and Nat-H exchanger present in the intestinal epithelial cells.
• This causes a large efflux of chloride and sodium ion and water into the gut, thereby causing the severe diarrhea that characterizes cholera.

Given:

$\rm\frac{?}{11}\ of\ \sqrt{125}=\frac{55}{?}\ of \ \sqrt{256}$

Concept used:

Using the BODMAS rule:

Calculation:

According to the question,

⇒ $\rm\frac{?}{11}\ of\ \sqrt{125}=\frac{55}{?}\ of \ \sqrt{256}$

⇒ $\rm\frac{?}{11} × 5\sqrt {5} =\frac{55}{?} × 16$

⇒ ?² = $\frac{55}{5\sqrt {5}}$ × 16 × 11

⇒ ?² = $\frac{11}{\sqrt 5}$ × 16 × 11

⇒ ?2 = $\frac{11^2 \times 4^2}{\sqrt 5} = \frac{44^2}{\sqrt 5}$ 

⇒ ?2 = $\frac{44}{ \sqrt[4] 5}$ 

Therefore, "$\frac{44}{ \sqrt[4] 5}$" is the required answer.

Given:

(422 + 45) ÷ (30 + 37) = ? × 3

Concept used:

Using BODMAS rule:

Calculation:

According to the question,

⇒ (422 + 45) ÷ (30 + 37) = ? × 3

⇒ (1764 + 45) ÷ (67) = ? × 3

⇒ (1809) ÷ (67) = ? × 3

⇒ 27 = ? × 3

⇒ ? = 9

Therefore, "9" is the required answer.

Given:

$\frac{5\times 5+4\times 4+2\times 5\times 4}{5\times 5-4\times 4}=?$

Concept used:

(a + b)² = a² + b² + 2ab

(a² - b²) = (a + b)(a - b)

Calculation:

According to the question,

⇒ $\frac{5^2+4^2+2\times 5\times 4}{5^2-4^2}=?$

⇒ $\frac{(5+4)^2}{(5+4)(5-4)}=?$

⇒ $\frac{(5+4)}{(5-4)}=?$

⇒ ? = 9

Therefore, "9" is the required answer.

Given:

The L.C.M. of two different numbers are 30

Concept: 

L.C.M × H.C.F = A × B

Where, 

L.C.M of the numbers A and B.

H.C.M of the numbers A and B.

Calculation:

⇒ L.C.M × H.C.F = A × B

The above formula can be written as:

⇒ L.C.M × H.C.F = (H.C.F × a) × (H.C.F × b)

Where, 

a and b are distinct prime factors.

Now,

⇒ L.C.M × H.C.F = H.C.F × a × H.C.F × b

⇒ L.C.M = H.C.F × a × b

⇒ 30 = H.C.F × a × b

Now, H.C.F must be a factor of 30. 

 

From Options it can be inferred that 12 is not a factor of 30.

 

Therefore, "12" is the required answer.

Shortcut Trick

Case 1: Removal of 780 units machine reduces average by 30 ⇒ 780 − k = 30(n − 1)

Case 2: Addition of 0 units machine reduces average by 90 ⇒ k − 0 = 90(n + 1)

Substitute k = 90n + 90 in first equation: 780 − (90n + 90) = 30n − 30

690 − 90n = 30n − 30 ⇒ 120n = 720 ⇒ n = 6

Average k = 90(6 + 1) = 630 units. Total output = 6 × 630 = 3780 units.

∴ The correct answer is 3780 units.

Alternate Method

Given:

Number of machines = n | Average output = k units/day

Value of machine excluded = 780 units | Value of machine included = 0 units

Formula Used:

Total Output = Number of Machines × Average Output

Calculations:

⇒ Total initial output = n × k

⇒ When 780 is excluded: (nk − 780) ÷ (n − 1) = k − 30

⇒ nk − 780 = (n − 1)(k − 30) = nk − 30n − k + 30

⇒ 30n + k = 810 ... (Eq. 1)

⇒ When a dead machine (0 units) is included: (nk + 0) ÷ (n + 1) = k − 90

⇒ nk = (n + 1)(k − 90) = nk − 90n + k − 90

⇒ k − 90n = 90 ⇒ k = 90n + 90 ... (Eq. 2)

⇒ Substituting (Eq. 2) in (Eq. 1): 30n + (90n + 90) = 810

⇒ 120n = 720 ⇒ n = 6

⇒ k = 90(6) + 90 = 630

⇒ Total Output = nk = 6 × 630 = 3780 units

∴ The correct answer is 3780 units.

Additional Information

Net Deviation Principle

In any average problem, the sum of deviations from the average is always zero. If an item is added or removed, the total change in the sum equals the deviation of that item from the original average.

Impact of Adding Zero

When a zero-value item is added to a set, the total sum remains constant, but the average decreases because the denominator (count) increases: New Avg = Old Sum ÷ (n + 1).

Average Property

If every element in a set is increased or decreased by a constant value 'x', the average also increases or decreases by 'x' respectively.

Given:

A person constructs 20 percent of the road on the first day,

30 percent of the remaining road on the second day,

50 percent of the remaining road on the third day,

and the rest 7 km road on the fourth day.

Calculation:

Let the length of the road = x km

The amount of work done on the first day, A = 20% of x = 0.2x

The amount of work done on the second day, B = 30% of (x - 0.2x)

⇒ B = 30% of 0.8x

⇒ B = 0.3 of 0.8x = 0.24x

Remaining work after second day = x - (0.2x + 0.24x) = 0.56x

The amount of work done on the third day = 50% of 0.56x = 0.28x

Remaining work after third day = x - (0.2x + 0.24x + 0.28x) = 0.28x

According to the question,

⇒ 0.28x = 7

⇒ x = $\frac{7}{0.28}$ = 25 km

Therefore, "25 km" is the required answer.

Given:

A retailer buys a computer at 30,000.

He spent some overhead expenses on it and sells the computer for 43750 at a profit of 25 percent.

Selling price = Cost price × (100% + Profit%)

Calculation:

According to the question,

Cost price of the computer = Rs. 30000

Selling price = Rs. 43750

Let 'C' be the cost price including the overhead expenses.

Now, 

⇒ S.P = C × (100% + 25%)

⇒ 43750 = C × 125%

⇒ C = 43750 × $\frac{100}{125}$ = 35000

Therefore, the overhead cost = Rs. 35000 - Rs. 30000 = Rs. 5000

The required percent = $\frac{5000}{30000}$ × 100 = 16.67%

Overhead expenses is 16.67% of cost price. 

Therefore, "16.67%" is the required answer.

Given:

By selling 16 pencils for Rs. 20, a man incurred a loss of 1 percent

Concept:

Selling price = (100% + Profit%) × Cost Price

Selling price = (100% - Loss%) × Cost Price

Calculation:

According to the question,

First case:

Selling Price = Rs. 20

Loss% = 1%

Now,

⇒ 20 = (100% - 1%) × C.P

⇒ 20 = 99% × C.P

⇒ C.P = $\frac{20}{99}$ × 100

Now, cost price of 16 pencils = Rs. $\frac{20}{99}$ × 100

Cost price of 1 pencils = Rs. $\frac{20}{99 × 16}$ × 100

Again according to the question,

Second case:

To earn 32% in each pencil.

Selling price of 1 pencil = $\frac{20 × 100}{16 × 99}$ × (100% + 32%)

Selling price of 1 pencil = $\frac{20 × 100}{16 × 99} × \frac{132}{100}$

It can be written as:

In Rs. $\frac{20 × 100}{16 × 99} × \frac{132}{100}$, the number of pencil bought = 1

In Rs. 1, the number of pencil bought = $\frac{16 × 99}{20 × 100} × \frac{100}{132}$

In Rs. 20, the number of pencil bought = $\frac{16 × 99}{20 × 100} × \frac{100}{132}$ × 20 = 12

Therefore, "12" is the required answer.

Given:

An item is purchased at Rs. 720, and 10 percent profit is earned,

Concept:

Selling price = (100% + Profit%) × Cost Price

Selling price = (100% - Loss%) × Cost Price

Calculation:

According to the question,

Selling price = (100% + 10%) of 720

⇒ Selling price = 110% of 720

⇒ Selling price = $\frac{110}{100}$ × 720 = 792

Therefore, "Rs. 792" is the required answer.

Given:

A man has 15.4 kg potatoes.

From the first part: he uses potatoes to make ajiaco, aligot, aloo pie in ratio 2 ∶ 3 ∶ 4.

From the second part: he uses potatoes to make cheese fries, chips, coddle in the ratio 5 ∶ 7 ∶ 4.

He uses the same quantity of potatoes to make ajiaco and cheese fries.

Calculation:

Let the amount of potatoes used for making ajiaco, aligot and aloo pie are 2x, 3x and 4x respectively.

Let the amount of potatoes used for making cheese fries, chips and coddle are 5y, 7y and 4y respectively.

According to the question,

⇒ 2x = 5y    ---(i)

Now,

The total quantity of potatoes used in both part, T = 2x + 3x + 4x + 5y + 7y + 4y = 15.4 kg

⇒ T = 9x + 16y = 15.4    ---(ii)

On solving the equation (i) and (ii), we get,

⇒ y = 0.4

Now, 

The amount of potatoes required for making coddle = 4y = 4(0.4) = 1.6 kg

Therefore, "1.6 kg" is the required answer.

Given:

4 years ago age of A was 1.5 times of that of B.

The difference between their ages after 4 years will be 20 years.

Concept:

The age difference between two people remains constant, regardless of whether you look at their ages n years ago or n years in the future.

Or,

The gap in the age never changes.

Calculation:

According to the question,

Case 1: 4 years ago age of A was 1.5 times of that of B.

It can be written as:

The ratio of A to B = $\frac{3}{2}$

Let the age of A 4 years ago = 3x

Let the age of B 4 years ago = 2x

Case 2: After 4 years the difference in their age will be 20 years.

The difference between the ages always remains constant.

Therefore, the gap in their age 4 years ago is the same as 20 years.

Therefore, 

⇒ 3x - 2x = 20

⇒ x = 20

The age of A 4 years ago = 3 × 20 = 60

The present age of A = 60 + 4 = 64 years

Therefore, "64 years" is the required answer.

Given:

Arun lent Rs. 4000 in two parts. He lent each part for a year.

He lent Rs. 2500 at 12 percent p.a.

The remaining at 10 percent p.a. simple interest. 

Formula used: 

S.I = $\frac{P \times R \times T}{100}$

Where, 

S.I = Simple interest

P = Principal

R = Rate of interest

T = Time period

Calculation:

Let 'R' be the effective rate.

According to the question,

Total Principal = Rs. 4000

First Scheme Principal = Rs. 2500

Second Scheme Principal = Rs. 4000 - Rs. 2500 = Rs. 1500

Now,

⇒ $\frac{4000 \times R \times 1}{100}$ = $\frac{2500 \times 12 \times 1}{100}$ + $\frac{1500 \times 10 \times 1}{100}$

⇒ 4000R = 30000 + 15000

⇒ 4000R = 45000

⇒ R = 11.25%

Therefore, "11$\frac{1}{4}$%" is the required answer.

Given:

A train running at a speed of 54 km/hr crosses a man standing on the platform in 32 seconds,

Concept:

1. Length of Train = Speed of Train × Time required to cross a standing man
2. (Length of Train + Length of platform) = Speed of train × Time required to cross a platform

Calculation:

The speed of train = 54 km/hr = 54 × $\frac{5}{18}$ = 15 m/sec

Length of train = 15 × 32 = 480 m

According to the question,

Let 't' is the time required to cross platform. 

⇒ 480 + 720 = 15 × t

⇒ 1200 = 15 × t

⇒ t = 80 sec

Therefore, "80 seconds" is the required answer.

Given: 

Two cars P and Q start at the same time from A and B which are 240 km apart.

If the two cars travel in opposite directions, they meet after 2 hour

If they travel in the same direction (from A towards B) P meets Q after 8 hours.

Formula used:

Case 1: When two bodies towards each other.

Distance between A and B = (R_P + R_Q) × time of meeting 

Case 2: When two bodies moves in the same direction.

Distance between A and B = (RP - RQ) × time of meeting

Where, 

R_P = Speed of car P

RQ = Speed of car Q

Calculation:

According to the question,

Case 1: If the two cars travel in opposite directions, they meet after 2 hour.

⇒ 240 = (RP + RQ) × 2

⇒ RP + RQ = 120   ---(i)

Case 2: If they travel in the same direction (from A towards B) P meets Q after 8 hours.

⇒ 240 = (RP - RQ) × 8

⇒ RP - RQ = 30   ---(ii)

Now, on solving the equation (i) and (ii), we get,

⇒ RP = 75 km/hr

Therefore, "75 km/hr" is the required answer.

Given:

A can do a certain work in 20 days and B can do the same work in 24 days.

A works alone for 1 day, then B works alone for 2 days, then A works alone for 3 days, then B works alone for 4 days, and so on.

Formula:

1. The total unit of work = L.C.M of (a and b) units

Where, a and b are the amount of time taken by two persons.

Calculation:

The total unit of work = L.C.M of (20 and 24) = 120 units

Efficiency of A = 120/20 = 6 units a day

Efficiency of B = 120/24 = 5 units a day

Now,

According to the question,

The amount of work on 1st day = (6 × 1) units

The amount of work on 2nd and 3rd = (5 × 2) units

The amount of work by A on next 3 days = (6 × 3) units

and this will continue so on.

⇒ (6 × 1) + (5 × 2) + (6 × 3) + (5 × 4) + (6 × 5) + (5 × 6) + (6 × 1)   ... = 120 units

On 22nd day A had done the last 6 units of work.

Therefore, "22nd day" is the required answer.

Given:

Efficiency of A is 20 percent more than B,

B is 30 percent more efficient than C.

Calculation:

Let the efficiency of C = 100

The efficiency of B = (100% + 30%) of 100

The efficiency of B = 130% of 100 = 130

The efficiency of A = (100% + 20%) of 130

The efficiency of A = 120% of 130 = 156

Now, 

The ratio of the required ratio A : B : C = 156 : 130 : 100 = 78 : 65 : 50

Therefore, "78 : 65 : 50" is the required answer.

Given:

On decreasing the length and breadth of rectangle by 20 percent and 25 percent, respectively, the area of rectangle decreases by 200 cm2,

Formula used:

Area of rectangle = length × breadth

Calculation:

Let 'l' and 'b' be the original length and breadth of the rectangle.

Area of rectangle (original) = l × b

According to the question,

New length = (100% - 20%) of l = 80% of l = 0.8l

New breadth = (100% - 25%) of b = 75% of b = 0.75b

New area = 0.8l × 0.75b = 0.6lb

The required difference = lb - 0.6lb = 0.4lb

According to the question,

⇒ 0.4lb = 200

⇒ lb = $\frac{200}{0.4}$ = 500 cm²

Therefore, "500 cm²" is the required answer.

Given:

The volume of the chalk = 1.89 π cm3

The bigger radius = 0.6 cm

The smaller radius is 0.3 cm

Formula used:

The volume of a frustum of a cone:

V = $\frac{1}{3}$π(R2 + r2 + Rr)h

Where:

h is the height of the frustum.

R is the radius of the larger base (the top base) of the frustum.

r is the radius of the smaller base (the bottom base) of the frustum.

Calculation:

According to the question,

⇒ V = $\frac{1}{3}$π(R2 + r2 + Rr) × h

⇒ 1.89π = $\frac{1}{3}$ × π × (0.62 + 0.32 + (0.6 × 0.3)) × h

⇒ 1.89π = $\frac{1}{3}$ × π × (0.36 + 0.09 + 0.18) × h

⇒ 1.89 = $\frac{1}{3}$ × (0.63) × h

⇒ h = 9 cm

Therefore, "9 cm" is the required answer.

Given:

The value of fees per visit for paediatrician = Rs. 1000

The value of fees per visit for dentist = Rs. 800

Calculation:

The number of visit for Pediatrician = 8 + 15 + 12 + 7 + 11 = 53

Weekly income for Pediatrician = 53 × 1000 = Rs. 53000

The number of visit for Dentist = 12 + 14 + 10 + 11 + 15 = 62

Weekly income for Dentist = 62 × 800 = Rs. 49600

The required percentage = $\frac{53000-49600}{49600}$ × 100 = 6.85%

The weekly income of a pediatrician from hospital is 6.85 percent more than the weekly income of a dentist from hospital.

Therefore, "6.85%" is the required answer.

Given:

The following bar graph shows the distance (in km) between two cities and speeds (in km/hr) of a boy to cover the respective distances

Calculation:

The total distance from A to F = 80 + 120 + 90 + 60 + 42 = 392 km

Time required to travel from A to B = 80/16 = 5 hr

Time required to travel from B to C = 120/40 = 3 hr

Time required to travel from C to D = 90/20 = 4.5 hr

Time required to travel from D to E = 60/30 = 2 hr

Time required to travel from E to F = 42/12 = 3.5 hr

Total Time from A to F = 5 + 3 + 4.5 + 2 + 3.5 = 18 hr

Average speed = $\frac{392}{18}$ = 21.78 km/hr

Therefore, "21.78 km/hr" is the required answer.

The correct answer is 'will not spend enthusiastic'

 Key Points

• Adverbs are used to modify verbs.
• Here, 'enthusiastic' is an adjective trying to modify the verb 'spend', which is grammatically incorrect. Instead, the adverb 'enthusiastically' should be used.
• The correct phrase should be 'not spend enthusiastically'. This phrase correctly indicates how the spending is done (i.e., with enthusiasm), which is what an adverb is meant to do.
• The verb 'spend' represents an action, and to describe the manner of that action, we should use an adverb. In the English language, adverbs often end in '-ly', such as 'enthusiastically'.

Therefore, the correct answer is Option 3.

The correct answer is 'Once the floods sets in for two to'

 Key Points

• The subject 'the floods' is a plural noun, so it needs the plural verb 'set' rather than the singular verb 'sets'.
• Hence, the correct phrasing should be 'Once the floods set in for two to'.
• The subject-verb agreement rule in English grammar states that a verb must agree in number with its subject. 'Floods' is a plural subject, so the plural form of the verb should be used.
• The verb 'set' in this context is referring to when the floods begin or start, which is why it should agree with the plural subject 'floods'.

Therefore, the correct answer is Option 1.

The correct answer is 'are separated from'

 Key Points

• The verb form 'is separate' doesn't match the subject 'Tea leaves', which is plural. The correct form should be 'are separated', aligning with the number of the subject.
• The preposition 'from' is appropriate in this context as it indicates that the leaves are separated away 'from' the liquid.
• According to English grammar rules, the proper agreement between the subject and verb is essential. Hence, as 'Tea leaves' is a plural subject, it should be followed by the plural verb form 'are'.
• Also, using 'separated' instead of 'separate' makes the sentence grammatically sound because the process of separating is ongoing during the preparation of tea.

Therefore, the correct answer is Option 3.

The correct answer is 'at too great a distance'

 Key Points

• The original phrase, 'at a too great distance', is incorrect because 'too' is not correctly placed. It should come before 'great a distance', not after 'a'.
• The correct placement of 'too' before 'great a distance' would properly indicate the excessive distance that is implied in the sentence.
• Using 'too' before an adjective but after the article 'a' creates an awkward and incorrect sentence structure, according to the rules of English grammar.
• The phrase 'at too great a distance' is a standard English phrase that conveys the idea that something is at such a great distance that it causes some kind of problem, hindrance, or challenge.

Therefore, the correct answer is Option 1.

The correct answer is 'soldier’s'

 Key Points

• The English possessive case is expressed with an added 's or an apostrophe alone, as per the subject (singular or plural) that is possessing something.
• In this case, we're referring to a house that belongs to a single soldier, hence, the possessive form 'soldier’s' is correct.
• The option 'soldiers’' is incorrect because the apostrophe after 's' is used when referring to multiple subjects possessing something, which isn't the context in this sentence.
• 'Soldier' and 'soldier ’' would be incorrect because these options don't indicate any possessive relationship.

Therefore, the correct answer is Option 1.

The correct answer is 'came, brutality'

 Key Points

• The sentence construction and its past tense context suggest that we use the past tense verb 'came' instead of 'come' or 'coming'.
• The second blank refers to a harsh or inhumane act, hence, the noun 'brutality' (which refers to savage physical violence) is more appropriate than the adjective 'brutal'.
• While the word 'come' could fit, because the sentence refers to past events, 'came' is more grammatically correct.
• While 'brutal' could possibly fit, because the context refers to actions (not just the nature of the actions), 'brutality' is more correct.

Therefore, the correct answer is Option 1.

The correct answer is 'with, had'

<br>

Key Points

• "Angry with" is the correct prepositional phrase in this context. When expressing anger towards a person.
• "Had" is the correct past perfect tense to indicate that the action (Naveen Kumar not being dressed properly) was completed in the past before the teacher became angry.
• Thus, according to the above mentioned explanation, option 1st is correct and therefore the answer.

The correct answer is 'QSPR'

 Key Points

• The most logical sequence starting from sentence S1, "Most of the people acquire," would be "their ancestral culture and tradition without questioning them (QSP), which makes them hesitant to accept new ideas and theories of the changing world (R)".
• The phrase 'their ancestral culture and tradition without questioning them' forms a complete idea following the initial fixed line, hence QSP.
• The statement 'which makes them hesitant' follows logically from the idea of unquestioning acceptance of traditions, leading to 'R' logically following after 'QSP'.
• The other sequences (SPRQ, QRSP, PQRS) do not maintain the logical and coherent flow of the ideas in the sentences.

Therefore, the correct answer is Option 3.

The correct answer is 'Misleading'

 Key Points

• Both 'Deceiving' and 'Misleading' have similar meanings. They both imply causing someone to believe something that is not true.
• In English, synonyms are words that have similar meanings. 'Misleading' is an appropriate synonym for 'Deceiving'.
• By choosing 'Misleading', we align with the context of the original sentence, maintaining its meaning while changing the phrasing.
• Other words provided like 'Honest', 'Composed', and 'Stolid' do not carry a similar meaning to 'Deceiving'.

Therefore, the correct answer is Option 1.

 Additional Information

• Honest: truthful, sincere
• Composed: calm; collected
• Stolid: calm, dependable, showing little emotion or animation

The correct answer is 'Approve'

 Key Points

• To 'Rebuff' means to reject someone or something in an abrupt or ungracious manner. Its antonym 'Approve' implies accepting or agreeing to something.
• Antonyms are words that have opposite meanings. So, 'Approve' fits as it is the opposite of 'Rebuff'.
• The use of 'Approve' in place of 'Rebuff' would reverse the meaning of the original sentence.
• The other options 'Bruise', 'High-spirited', and 'Sob' do not carry the antonym-meaning to 'Rebuff'.

Therefore, the correct answer is Option 1.

 Additional Information

• Bruise: an injury where blood vessels under the skin are broken
• High-spirited: full of enthusiasm or determination
• Sob: to cry noisily, taking in deep breaths

The correct answer is 'advisary'

 Key Points

• The word 'advisary' is not a correctly spelled word. The correct spelling is 'adversary', meaning one's opponent or enemy.
• 'Stamina', 'phenomena', and 'tactic' are all correctly spelled words, making them inappropriate answers to the question asking for the incorrectly spelled word.
• Correct spelling is crucial for conveying the right meaning. Hence, 'advisary' is the incorrect spelling here.
• It's important to note that 'advisary' is not just a misspelling of 'adversary', it doesn't exist as a word in English.

Therefore, the correct answer is Option 4.

The correct answer is 'Arrangement'

 Key Points

• 'Arrangement' is the correctly spelled word in this context. The others are variations of the correct spelling 'Arrangement'.
• Spelling errors can significantly change the meaning of a word or make it non-existing.
• The other options such as 'Arrangment', 'Arangement', and 'Arrangemant' are misspellings of the word 'Arrangement'.
• It is important to remember the correct spellings as it can drastically change the context of a sentence or phrase when used.

Therefore, the correct answer is Option 2.

The correct answer is 'An easy pleasant job that also pays well. '

 Key Points

• 'A plum job' is an idiom in English that refers to a job which is considered easy and pleasant, but also pays well.
• Idioms often cannot be translated literally and need to be understood in the context they are used.
• This idiom is derived from the use of the word 'plum' as an adjective meaning 'choice' or 'desirable', frequently in the term 'plum job'.
• The other options such as 'An expression of good-luck', 'A situation of having no job', and 'A difficult job with many hardships' do not convey the meaning of this idiom.

Therefore, the correct answer is Option 4.

The correct answer is 'Be very cautious'

 Key Points

• 'To walk the tightrope' is an idiom that means to maintain a careful balance between different conditions, factors, or interests.
• This idiom is derived from the literal act of walking on a tightrope, where caution is required to keep balance and avoid falling.
• Therefore, the answer 'Be very cautious' best fits the meaning of this idiom.
• The other options such as 'Be very nervous', 'Be well trained', and 'Be an expert' do not accurately convey the meaning of this idiom.

Therefore, the correct answer is Option 2.

The correct answer is 'Delirium'

 Key Points

• 'Delirium' is a condition of severe confusion and rapid changes in brain function, often caused by physical or mental illness.
• This term directly corresponds to the definition "Mental disturbance caused by an illness."
• 'Dilemma', 'Discrepancy', and 'Diurnal' do not match the definition provided. A dilemma is a difficult choice or decision; a discrepancy is an inconsistency or mismatch; diurnal means daily or of the daytime.
• Given the definition and the options provided, 'Delirium' is the term that best matches the definition.

Therefore, the correct answer is Option 2.

The correct answer is 'The consensus amongst the seven-member countries on countering China.'

Key Points

• In the given passage, the second strong message from the G-7 summit as stated was the consensus among its seven-member countries about countering China.
• The first message, mentioned before the second in the passage, was driven by the US President, and related to commitment on global challenges, including vaccine donation and investment in the pandemic recovery plan.
• While the other options listed have been addressed in varying degrees within the text, they do not align directly with the text's clear mention of the second message.

Therefore, the correct answer is Option 4.

The correct answer is 'Friendliness and happiness.'

Key Points

• The word 'Bonhomie' has been used in the passage to describe the spirit of good-natured friendliness among the G-7 leaders.
• 'Bonhomie' is a French origin term meaning pleasant and friendly atmosphere or good natured easy friendliness.
• The context of the sentence clearly suggests a positive and friendly atmosphere, rather than anything negative or strategically savvy.
• Thus, the 'Friendliness and happiness' meaning aligns correctly with the use of 'Bonhomie' in the text.

Therefore, the correct answer is Option 1.

The correct answer is 'America’s economy and jobs recovery plan.'

Key Points

• 'Build Back Better' has been identified as a White House term for America's plan for economic recovery and job creation.
• The passage suggests that this term was even adapted as the slogan for the G-7.
• The phrase 'Build Back Better' implies an aim to not just recover, but improve upon previous states, thus it's used here to signify an ambitious plan for economic growth and job creation.
• The other options presented, while significant in broader discussions, do not accurately capture what 'Build Back Better' represents within this context.

Therefore, the correct answer is Option 2.

The correct answer is 'Build Back Better'

Key Points

• The passage clearly states that the slogan for the G-7 was 'Build Back Better'.
• This term is directly referenced as the slogan, making this the correct choice over the other options.
• The slogan 'Build Back Better' was used to signify an aim to improve and refresh economies and job markets in the wake of the pandemic.
• While other phrases were also present and significant throughout the meeting, 'Build Back Better' was explicitly termed as the slogan.

Therefore, the correct answer is Option 4.

The correct answer is 'The EU'

Key Points

• The passage suggests that on economic issues, the European Union (EU) is more representative than the individual European countries that are part of the G-7.
• This is because the EU is an economic and political union involving 27 European countries, encompassing territories beyond those of individual G-7 European member countries.
• While China, the USA, and India are all significant in the global economic context, the passage does not suggest them as more representative units in economic issues over the individual European G-7 member countries.
• The context of the sentence in the passage directly suggests a comparison between the EU and individual European G-7 members, rather than inclusion of other nations or entities mentioned in the choices.

Therefore, the correct answer is Option 4.
