The correct answer is angle of reflection

• Reflection: The phenomena in which light ray is sent back into the same medium from which it is coming, on interaction with boundary, is called reflection.
• Laws of reflection:

1. it states that, if a light ray is reflected from a plane flat polished surface its angle of the incident will always be equal the angle of reflection  i.e., The angle of incidence (θ i ) = Angle of reflection (θ r )
2. Incident ray, reflected ray, normal all lies on the same plane.

 

Explanation:

• The angle of incidence is the angle between incident ray and the normal.
• So, if the ray of light is falling on the normal, it is making 0 ° with normal.
• We know that, the angle of incidence is equal to the angle of reflection, So we can say that the angle of reflection is also 0 °

So, the correct option is 0 °

Given:

Simple interest for sum of Rs. 2460 for two years = 68 + Simple interest for Rs. 2290 for two years

Concept used:

Simple interest = P × R  ×  T/100

Where:- 

P :- Principal

R :- Rate

T :- Time 

Calculation:

Here,

P₁ = Rs. 2460

P₂ = Rs. 2290

R = Rate of interest

Time = 2 years

According to question,

⇒ 2460  ×  R  × 2/100 = (2290  ×  R  ×  2/100) + 68

⇒ R  ×  2/100  × [2460 - 2290] = 68

⇒ 2R = 68  ×  100/170

⇒ 20%

∴ Option 4 is correct.

Given:

Suresh present age = 2/5^th of His father's present age

After some years, 

Suresh age = 75% of his father's age

Calculation:

Suresh's present age is 2/5 of his father's present age.

S = 2/5F

After x years, Suresh's age will become 75% of his father's age at that time.

S + x = 0.75 (F + x)

We need to find by what percent the father's age will increase during this period.

Express x in terms of F

We already know S= (2/5)F

Substituting this in the second equation:

⇒ (2/5)F + x = 0.75 (F + x)

⇒ (2/5)F + x = 0.75F + 0.75x

⇒ (x − 0.75x) = 0.75F − (2/5)F

⇒ 0.25x = (15F - 8F)/20

⇒ 0.25x = (7/20)F

⇒ x = [(7/20)F] / 0.25

⇒ x = (7/5)F

The father's age increases from F to (F+x), so:

Father's age increased by = F + x = F + (7/5)F = (12/5)F

The percentage increase in the father's age is:

Percentage Increase = {[(12/5)F - F] / F} * 100

Percentage Increase = {[(7/5)F] / F} * 100 = (7/5) * 100 = 140%

∴ The correct answer is Option 3).

Given:

Product of two numbers = 3645

Calculation:

Let the number of cubes fit inside the rectangular box = n

Length of rectangular box = 3.2 m

Breadth of rectangular box = 2 m

Height of rectangular box = 1.2 m

Side of cube = 40 cm = 0.4 m

According to question,

⇒ 3.2 × 2 × 1.2 = n × (0.4)³

⇒ n = 120

∴ Option 1 is correct.

Given:

Speed of man from A to B = 8 km/h

Speed of man from B to A = 20 km/h

Time taken to cover the whole journey = 63/8 hour

Concept used:

Average speed = 2xy/(x + y)

Speed = distance/time

Calculation:

Speed of man from A to B = 8 km/h

Speed of man from B to A = 20 km/h

Time taken to cover the whole journey = 63/8 hour

Let total distance covered in whole journey (A to B and B to A) = D

Average speed = 2 × 8 × 20/(20 + 8)

Average speed = 320/28

Speed = Distance/time 

320/28 = D × 8/63

D = 90 km

Thus, Distance between A to B = 90/2 = 45 km.

∴ Option 1 is correct.

Given:

14(3/5) + 17(5/6) + 7(1/3) = ?/6 + 20

Calculation:

⇒ 14(3/5) + 17(5/6) + 7(1/3) = ?/6 + 20

⇒ 42/5 + 85/6 + 7/3 = ?/6 + 20

⇒ (252 + 425 + 70)/30 =?/6 + 20

⇒ 747/30 - 20 = ?/6

⇒ 4.9 = ?/6

⇒ ? = 29.4

∴ Option 1 is correct.

Given:

Pure milk = Rs.60 per litre

Mixture with 80 litre of water = Rs.40 per litre

Calculation:

According to the rule,

Water       Milk

(0 litre)       Rs.60

 

       Mean price

         Rs.40

 

(60 - 40)        (40 - 0)

  20                    40

   1          :           2

∴ Water : milk = : 20 : 40 = 1 : 2

∴ Quantity of milk in mixture = 2 × 80 = 160 litre

∴ Option 4 is correct.

Given:

Three numbers ratio = 3 : 4 : 5

LCM = 1800

Calculation:

Let the three numbers are = 3x, 4x, 5x

The greatest number = 30 × 5 = 150

∴ Option 1 is correct.

Given:

A man drive a car first 160 km at the speed 120 km/hr.

Next 70 km at the speed of 56 km/hr.

Next 240 km at the speed of 180 km/hr.

Concept used:

Total time taken = Distance/speed

Calculation:

Total distance = 160km + 70 km + 240 km = 470 km

Total time taken = (160/120 + 70/56 + 240/180) = 47/12 hrs

Average speed = 470 × 12/47 = 120 km/hr

∴ Option 4 is correct.

Given:

Ram's income is successively increased = 30%, 20%

Concept used:

Successive rate = x + y + xy/100

Calculation:

Number of visitor in Punjab = n

According to question,

the number of visitors visited Rajasthan in 2020 is 4500 that is 25% more than the number of visitors visited Punjab in 2021.

⇒ 125% of n = 4500

n = 4500 × 100/125 = 3600

Number of visitors in Punjab = 24%

⇒ 24% x = 3600

x =  3600 × 100/24 = 15000

∴ Option 4 is correct.

Given:

Present age of Sukhe and Diljit are ratio = 6 : 7

After 2 years, 

Ratio of Diljit and guru = 11 : 8

Present age average age of Sukhe and Diljit = 36

Calculation:

Sum of their ages = 36 × 3= 108

Present age of Sukhe = 6x

Let present age of Diljit = 7x

Guru present age = 108 - (6x + 7x) = 108 - 13x

After two years Diljit age = 7x + 2 

After two years Guru age = (108 - 13x) + 2 = 110 - 13x

Ratio of Diljit and Guru age = 11 : 8

⇒ 7x + 2/110 - 13x = 11/8

⇒ 56x + 16 = 1210 - 143x

⇒ 199x = 1194

x = 6

Guru present age = 108 - 13x = 108 - 13 × 6 = 108 - 78 = 30

∴ Option 3 is correct.

Calculations:

⇒ TSA = 2 × (12 × 16 + 16 × 18 + 18 × 12)

⇒ TSA = 2 × (192 + 288 + 216)

⇒ TSA = 2 × 696

⇒ TSA = 1392 sq. cm

∴ The correct answer is 1392 sq. cm.

Additional Information

Volume of Cuboid

The space occupied by the cuboid is calculated as Volume = Length × Width × Height (l × w × h).

Lateral Surface Area

The area of the four vertical faces (excluding top and bottom) is LSA = 2h(l + w).

Diagonal of Cuboid

The longest rod that can be placed inside a cuboid has length d = √(l² + w² + h²).

Calculation:

Total profit = Rs. 6388

Ravindra's investment = Rs. 8400

Nusrat's investment = Rs. 6500

After 6 months,

Investment of Ravindra = 8400 + 110% of 8400 = 17640

Investment of Nusrat = 6500 + 120% 0f 6500 = 14300 

Ratio of their investment = 882 : 715

⇒ 1597 unit = 6388

1 unit = 4

Ravindra's profit = 4 × 882 = Rs. 3528 

∴ Option 2 is correct.

Given:

Pipe A filled at the rate of 20 litres per minutes.

Pipe B alone filled a tank in 10 hours.

Both pipes are opened together then tank is filled in 6 hours. 

Calculation:

Pipe B alone filled the tank = 10 hours

Both pipe can filled the tank = 6 hours

Here,

B              A + B

10              6

         30

3                 5

Efficiency of A = 5 - 3 = 2 unit

A alone can filled the tank = 30/2 = 15 hours = 15 × 60 = 900 min

But A filled in 1 min = 20 litre

In 900 min. filled by A = 900 × 20 = 18000 litre

∴ The capacity of tank is 18000 litre.

∴ Option 1 is correct.

Here,

If in June, the number of boys and number of girls increased by 21.5% and 16(2/3)% respectively as compared to that in April.

Number of boys in April = 200

Number of girls in April = 300

Number of boys in June = 200 × 21.5/100 + 200 = 243

Number of girls in June = 300 × 50/300 + 300 = 350

Total number of boys and girls in June = 243 + 350 = 593

∴ Option 1 is correct.

Given:

There are three friends Mina, Sheena and Rita and their ages are (a + 4), (a - 4) and (a - 8) years respectively.

The average age of Mina and Sheena together is 24 years.

Calculation:

 The average age of Mina and Sheena together is 24 years.

Sum of age of Mina and Sheena = 24 × 2 = 48 years

⇒ (a + 4 ) + (a - 4) = 48 years

2a = 48 years 

a = 24 years

Present age of Rita = (a - 8) = (24 - 8) = 16 years

∴ Option 4 is correct.

Given:

The H.C.F. of 0.42, 0.14 and 0.35.

Concept used:

HCF of a/b, c/d = HCF of (a,b)/LCM of (c,d)

Calculation:

Here, The numbers are 0.42, 0.14 and 0.35.

⇒ 42/100, 14/100, 35/100

⇒ 7/100 = 0.07

∴ Option 3 is correct.

Here, 

The production of the items A on Wednesday = 70

The production of items C on Monday = 75

The ratio between the production of the items A on Wednesday to the production of items C on Monday = 70 : 75 = 14 :15

∴ Option 2 is correct.

Given: 

⇒ 3599.98 ÷ 8.92 + 74.98% of 799.92 = ?

Concept used:

Follow VBODMAS rule to solve this question, as per the order given below.

Step - 1: Parts of an equation enclosed in 'Vinculum Bar' must be solved first.

Step - 2: Parts of an equation enclosed in 'Brackets' must be solved second, and following BODMAS rule in the bracket

Step - 3: Any mathematical 'Of' or 'Exponent' must be solved next.

Step - 4: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated.

Step - 5: Last but not the least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

Calculation: 

3599.98 ÷ 8.92 + 74.98/100 × 799.92 = ?

3599.98 ÷ 8.92 + 74.98% of 799.92 = ?

⇒ 3599.98 ÷ 8.92 + 599.78 = ?

⇒ 403.56 + 599.78 = 1003. 34 ≈ 1000

∴ Option 1 is correct.

सही उत्तर: 'समय पर किया गया काम सफल होता है।'

Key Points

• अनुच्छेद के अनुसार, समय का महत्त्व यह है कि उस पर किया गए काम का असली मूल्य होता है।
• यदि काम समय पर नहीं किया जाता, तो उसका परिणाम निष्फल हो सकता है, चाहे वह कितना ही अच्छा क्यों न हो। इस तरह, जब काम समय पर किया जाता है, वह सफलता और असरदार परिणाम लाता है।

Additional Information

अन्य विकल्पों की व्याख्या:

• समय का जीवन में महत्त्व कम है: यह विकल्प अनुच्छेद के विचारों के विरुद्ध है क्योंकि वह समय के महत्त्व को महसूस कराता है।
• समय पर किया गया काम सफल नहीं होता है : यह विकल्प भी गलत है क्योंकि अनुच्छेद समय पर किया गया काम की प्रशंसा करता है।
• लोग समय की परवाह नहीं करते : यह विकल्प अनुच्छेद के विषय में कुछ भी नहीं कहता है, इसलिए इसे नकारा जा सकता है।

सही उत्तर: 'समय पर खेत की रखवाली नहीं करता'

Key Points

• अनुच्छेद के अनुसार, खेत का रखवाला इसलिए उपहास का पात्र बनता है क्योंकि वह समय पर खेत की रखवाली नहीं करता।
• जब काम समय पर नहीं किया जाता, तो उसका परिणाम निष्फल हो सकता है, उसकी सुरक्षा की व्यवस्था कितनी ही अच्छी क्यों न हो।

Additional Informationअन्य विकल्पों की व्याख्या:

• सदैव अपना काम दूसरों को सौंप देता है: यह विकल्प अनुच्छेद में कहीं भी स्पष्ट तौर पर वर्णित नहीं है।
• चिड़ियों का इंतजार करता है: अनुच्छेद में तो चिड़ियों की चर्चा होती है, लेकिन वहां यह नहीं कहा जाता है कि रखवाला उनका इंतजार करता है।
• खेत में पानी नहीं देता: खेत में पानी देने के बारे में अनुच्छेद में कहीं भी उल्लेख नहीं है।

सही उत्तर: 'फ़सल को लाभ न पहुँचे'

Key Points

• अनुच्छेद के अनुसार, बादलों द्वारा बरसाया गया जल यदि फ़सल को फलने-फूलने में मदद नहीं कर सकता, तो उसका बरसना व्यर्थ माना जाता है।
• इसका अर्थ है कि यदि किसी कार्य का परिणाम नहीं मिलता, तो उसका करना व्यर्थ होता है, चाहे वह कितना भी अच्छा हो।

Additional Informationबाकी विकल्पों की व्याख्या:

• गरमी शांत हो जाए: यह विकल्प अनुच्छेद के विचारों से संबंधित नहीं है।
• नदी-तालाब भर जाए: अनुच्छेद में नदी या तालाब के बारे में कहीं भी बात नहीं हुई है।
• चिड़ियों को पानी मिल जाए: अनुच्छेद चिड़ियों के पानी पाने के बारे में कहीं नहीं बताता है।

सही उत्तर: 'समय का सदुपयोग'

Key Points

• इस अनुच्छेद में समय के सदुपयोग पर बल दिया गया है। यदि कार्य सही समय पर किया जाता है, तो वह सफल और उपयुक्त होता है।
• अतः, "समय का सदुपयोग" इसे उपयुक्त शीर्षक देने की अवधारणा को स्पष्टता से प्रकट करता है।

Additional Informationअन्य विकल्पों की व्याख्या:

• किसान का पछतावा: अनुच्छेद में किसान के पछतावे के बारे में स्पष्ट उल्लेख नहीं है।
• चिड़ियों का खेत खाना: खेत की चिड़ियों द्वारा बर्बादी एक उदाहरण के रूप में दी गई है, लेकिन यह अनुच्छेद का मुख्य विषय नहीं है।
• बादल का बरसना: बादलों का बरसना भी एक उदाहरण है जो समय के सही उपयोग के महत्त्व को बताने के लिए दिया गया है। इसलिए, यह शीर्षक पूरे अनुच्छेद को कवर नहीं करता है।

सही उत्तर: 'अनवसर'

Key Points

• अवसर का समानार्थी शब्द "अनवसर" नहीं है। "अनवसर" अवसर का विलोम शब्द है और इसका मतलब होता है "अनुपयुक्त समय"।

Additional Information

बाकी विकल्पों की व्याख्या:

• स्थिति: हालांकि यह शब्द व्यापक है, लेकिन किसी खास स्थिति में, यदि उसे एक अवसर के रूप में देखा जाए, तो यह अवसर का समानार्थी हो सकता है।
• मौका: "मौका" अवसर का समानार्थी शब्द है, जिसका अर्थ होता है किसी विशेष समयावधि या स्थिति।
• संभावना: "संभावना" भी अवसर का समानार्थी हो सकता है, यदि इसे एक मौके या सुविधा की संभावना के रूप में देखा जाए।

The correct answer is "Something good that isn’t recognized at first".

Key Points 

• Let's look at the meaning of the given word.
• A blessing in disguise means "something that seems bad or unlucky at first, but results in something good happening later (ऐसा कुछ जो पहले बुरा या अशुभ लगता है, लेकिन बाद में कुछ अच्छा होता है)".
• ​Example: Being laid off was a blessing in disguise but within a month I got a much better job.
• From the above lines, we can say that "Something good that isn’t recognized at first" is the correct idiom/phrase for the given word.
• All the options are eliminated because of this reason.

Hence, option 1 is the correct answer.

The correct answer is "Mum’s the word".

Key Points 

• Let's look at the meaning of the given word.
• To keep quiet, To say nothing means "keep something secret; say nothing about something (कुछ गुप्त रखना; किसी चीज के बारे में कुछ नहीं कहना)".
• ​Example: Sheena managed to keep the school’s problems quiet to say nothing for a while.
• Mum’s the word means "when one tells someone or agrees with someone, to keep something a secret (जब कोई किसी को कुछ गुप्त रखने के लिए कहता है या किसी के साथ सहमत होता है)".
• ​Example: We want her birthday party to be a surprise, so please mum's the word.
• From the above lines, we can say that "Mum’s the word" is the correct idiom/phrase for the given word.
• All the options are eliminated because of this reason.

Hence, ​option 3 is the correct answer.

The correct option is "option 1".

Key Points 

• The error lies in option 1 of the sentence.
• Here, we can use "has" in place of "have" to make the sentence grammatically correct.
• If two or more subjects are joined with pronouns each, every, either, neither + of the + Noun then the noun will be plural, and the verb will be singular.
• Example: Either of the students is expected to come to the school.
• In the given sentence, "neither of" is given so we need a plural noun with a singular verb which is in not in option 1.
• All the options are eliminated because they all are correct.

Hence, option 1 is the correct answer.

Complete Sentence: Neither of them has/ any idea how long the/ body has been entombed.

Additional Information

• If two subjects joined with Not only...... but also, Neither...... nor, Either...... or then the verb will be according to the second subject.
• Example: Neither Dinesh nor his friends are doing well in the examination.
• Two or more Singular Subjects connected by or, nor, either ….. or, neither …. nor take a verb and noun both are the singular.
• Example: I don't like either Steve or Andre.

The correct answer is "asked us, "Where were all of you last night?"

Key Points 

• If the reported speech is in the form of an interrogative sentence, it can be constructed in two ways according to the structure of the Interrogative sentence it may begin with -Wh words (where, who, what, etc.) or using an auxiliary verb (is, am, are, was, were) and inverted comma is to enclose the exact words used by a speaker just after the question mark.
• Direct Speech: It is the speech in which the actual words of the speaker are reported within inverted commas.
• Example: Anusha said, "I am going."
• Indirect Speech: It is speech in which the substance or idea of the speaker's words is reported without using his actual words without inverted commas.
• ​Example: Sushil said that he was going.​
• Here, the sentence should be in an inverted comma as the actual words of the speaker are reported, and also there is a need for a question mark with the verb "asked". As per the given thing, two options show such a thing but the one which has "that" is also eliminated as we can't use "that" with direct speech.
• All the options are eliminated because of this reason.

Hence, option 2 is the correct answer.

Complete Sentence: Grandma asked us, "Where were all of you last night?"

Additional Information 

• Punctuation mark: A mark, such as a full stop, comma, or question mark, is used in writing to separate sentences and their elements and to clarify meaning.

• Example: When did Graeme leave for the market?
• Inverted comma: It is used to enclose the exact words used by a speaker.
• Example: He said, "The scheme will be announced tomorrow."
• Comma: The comma (,) is a punctuation mark that indicates a pause in a sentence, sets off words, phrases, or clauses, separates items in a list, and performs many other functions. The comma is one of the most versatile and commonly misused punctuation marks in English.
• Full stop: The full stop (.) also called period is used to mark the end of a declarative sentence or an imperative sentence.
• Example: Shweta speaks slowly.

The correct answer is "Array".

Key Points 

Let's look at the meanings of the given words:

• Example: Suresh achieved instant fame and notoriety with the release of his film.
• ​​​​​'Paucity' means less than enough of something; too little (संख्या या गुणवत्ता पर्याप्त से कम; थोड़ा, कुछ, कम).
• Example: The authorities had to cope with the paucity of information about the effects of the storm.
• 'Expatia': ​There is no such word in English or we can say that there is some spelling mistake in this word.
• The correct spelling is 'Expatiate' which means to speak or write about something in great detail or for a long time (किसी वस्तु के बारे में विस्तार से लंबे समय तक बोलना लिखना लिखना).

​Hence, the correct answer is option 2.

Additional Information 

• The synonyms of the word 'Expatiate' are expound, amplify, and dilate.
• Example of 'Expatiate' in a sentence.
• ​Example: *Shweta expatiated on her work for the duration of the meal.*​

• ​Example: The judge was satisfied that Dinesh was telling the truth.

• Q will be after P as it continues the further information about novelists through the pronoun "their" which says that novelists change something.
• R will be after Q as it continues the information about changes that novelists change their principle objectives to reflect those people.
• S will be after R and is the last one as it concludes the sentence and says that those people i.e. novelists change their principle objectives to reflect those critical theorists they think or admire should be better than them.

 

Hence, the correct arrangement is "PQRS".

Correct Order

Novelists have proved

P. impressionable, quick studies,

Q. recalibrating their aesthetic

R. objectives to reflect those of

S. the critical theorists they emulate.

Complete Sentence: Novelists have proved impressionable, quick studies, recalibrating their aesthetic objectives to reflect those of the critical theorists they emulate.

Key Points 

• Malicious means ​'characterized by malice; intending or intended to do harm (द्वेष द्वारा विशेषता; नुकसान करने का इरादा)'.
• ​Example: Ritesh was charged with malicious wounding.
• All the other options are contextually and meaningfully incorrect and are positive words but we need a negative word that is only shown as malicious.
• So, all the other options are eliminated because of this reason.

​​​​​​Hence, option 3 is the correct answer. 

Complete Sentence: Outside the court, they both said they would consider mounting a case against the police for malicious prosecution.

• ​Example: The system is archaic and unfair and needs changing.
• All the other options are contextually and meaningfully incorrect.
• So, all the other options are eliminated because of this reason.

​​​​​​Hence, option 3 is the correct answer.

The correct option is "option 3".

Key Points 

• The error lies in option 3 of the sentence.
• Here, we remove "the" article to make the sentence grammatically correct.
• Article: An article is used to modify a noun, which is a person, place, object, or idea.
• Example: A man, a car, a girl.
• Definite articles (The): The definite article "the" is used before the singular and plural nouns when the noun is specific or particular.
• Example: Gurmeet gets on the bus.
• According to article usage, articles before proper nouns such as person names, individual continent names, individual country names, individual city names, individual mountain names, island names, a single specified hill or peak, etc are omitted.
• In the given sentence, "Mount Everest" is a single specified peak and a proper noun and we can't use any article with a single specified peak.
• We have to omit "the" to make the sentence grammatically correct.
• All the options are eliminated because they all are correct.

Hence, option 3 is the correct answer.

Complete Sentence: The Indian expedition/ to Mount Everest is/ leaving next month.

Additional Information 

• Indefinite articles (A and An):
• A article: When the indefinite article comes before a word beginning with a consonant sound.
• Example: A book, a car.
• An article: When the indefinite article comes before a word beginning with a vowel sound.
• ​Example: An idea, an apple.

The correct answer is "as the magic-bullet solution to disposing of otherwise".

Key Points 

• The correct option lies in option 3 of the sentence.
• Here, we can use the preposition "of" with "disposing".
• "Dispose of" is a phrasal verb so we have to use it in this sentence.
• Dispose of somebody/something means 'to get rid of somebody/something that one do es not want or cannot keep (किसी से छुटकारा पाने के लिए/ कुछ ऐसा जो कोई नहीं चाहता या नहीं रखना चाहता)'.
• Example: Radioactive waste must be disposed of safely.
• Here, the only preposition used with "disposing" is "of" and without a preposition and with a bracket is also wrong as "disposing of" is a phrasal verb.
• All the options are eliminated because of this reason.

Hence, option 3 is the correct answer.

Complete Sentence: Incineration has been used for decades as the magic-bullet solution to disposing of otherwise persistent waste materials.

The correct answer is "PSQR".

Key Points 

• P will be the first sentence to start as it is contextually and meaningfully correct for the sentence after "The first ruler of the gods was Uranus, the personification of the sky" which adds more about the ruler through the pronoun "he" that he was married to Gaia.

• S will be after P as it continues the further information about the ruler whose name is Uranus and his wife Gaia that they have twelve children.

• Q will be after S as it continues the information about the children as described in S that the ruler's children will overthrow him as per future prediction so the ruler hid his children inside the earth to protect himself from being overthrown by his children.

• R will be after Q and is the last point as it adds more by saying that Gaia hated the ruler because of this reason and by adding "The children of the sky and the earth were known in the ancient sources as the Titans" makes the concluding statement of the paragraph.

Hence, the correct arrangement is "PSQR".

Correct Order

The first ruler of the gods was Uranus, the personification of the sky.

P. He was married to Gaia, the goddess of the earth.

S. Uranus had twelve children with Gaia.

Q. After a prophecy that his children would overthrow him, the original ruler of the world hid his children inside their mother (earth).

R. Gaia hated him for this.

The children of the sky and the earth were known in ancient sources as the Titans.

The correct answer is "corrupted".

Key Points 

• Debased means ​'lower the moral character of someone (किसी के नैतिक चरित्र को कमजोर करना)'.
• ​Example: Ritesh would not debase himself by entering such a popularity contest.
• Corrupted means ​'to cause somebody/something to start behaving in a dishonest or immoral way (अनुचित  अथवा अनैतिक व्यवहार के लिए प्रेरित करना; भ्रष्‍ट करना)'.
• ​Example: The whole system was corrupt. Every official Zeesha approached wanted money before helping her.

• Amenable means happy to accept something; willing to be influenced by somebody/something (खुशी से स्‍वीकार करने वाला; स्‍वेच्‍छा से प्रभावित होने वाला).

The correct answer is "Positive state of mind".

Key Points 

• Let's refer to the following lines from the passage:
• ​'A group of researchers has demonstrated that pleasure and positive states of mind are better for our health. This new intellectual approach to health is not only more powerful but also has no side effects.'
• Upon the perusal of the above lines, it is clear that a group of researchers has demonstrated that pleasure and positive states of mind are better for our health. These two are considered a new intellectual approach to health.
• All other options are eliminated because they are not mentioned in the passage and also are not considered as a new intellectual approach.

Hence, option 2 is the correct answer.
