The correct answer is 'in any case'.

Key Points

• The discourse marker "in any case" is used to indicate that the speaker is making a statement regardless of any other factors or conditions.
• In this context, the speaker implies that the person would not listen to them regardless of whether they tell them what they think or not.
• Other options like "meanwhile" and "in the meantime" are not suitable here as they are used to indicate simultaneous actions or events, which is not applicable in this sentence.

Therefore, the correct answer is Option 2.

Complete Sentence: "I can’t be bothered to tell him what I think; in any case he would not listen to me."

Additional Information

• Option 1: "meanwhile" is incorrect because it refers to events occurring simultaneously.

• Option 4: "somehow" is incorrect as it refers to achieving something in an unspecified way, which is irrelevant here.

The correct answer is 'On the contrary'.

Key Points

• The phrase "On the contrary" is used to introduce a contrasting idea or to refute a previous statement.
• The context of the sentence requires a discourse marker that indicates a contrary or opposite idea, which aligns with the meaning of "On the contrary".
• Options 2, 3, and 4 do not convey the required contrast or relevance in this sentence.

Therefore, the correct answer is Option 1.

Complete Sentence: "On the contrary, if the referee points his fingers, this indicates that someone has done something wrong."

• Option 2: "Whatever more" is irrelevant and does not fit the context.
• Option 3: "Briefly" suggests summarization, which is not suitable here.
• Option 4: "As regards" is used to introduce a topic, but it does not fit the meaning of the sentence.

The correct answer is 'Incidentally'.

Key Points

• The discourse marker "Incidentally" is used to introduce a new topic or to connect ideas in a casual or related manner.
• In this sentence, "Incidentally" is appropriate because it introduces a query about whether the person has been to the local library, which might not be directly related to the ongoing conversation.
• Options 1, 2, and 3 do not fit the context or provide the correct discourse marker for this sentence.

Therefore, the correct answer is Option 4.

Complete Sentence: "Incidentally, have you been to the local library yet?"

Additional Information

• Option 1: "Sort of" is incorrect because it does not serve as a proper discourse marker in this context.
• Option 2: "Frankly" is incorrect; it is used to express an honest opinion, which does not fit the sentence.
• Option 3: "All the same" is incorrect as it implies contrast or concession, which is not required here.

The correct answer is 'To a large extent'.

Key Points

• The discourse marker "To a large extent" is the most appropriate choice in this context as it conveys the idea of the statement being largely true.
• The sentence highlights that women are healthier and living longer than ever before, and "To a large extent" appropriately introduces this generalization.
• Options 2, 3, and 4 are not suitable as they fail to match the required tone and context of the sentence.

Therefore, the correct answer is Option 1.

Complete Sentence: "To a large extent women are healthier and are living longer than ever before: indeed on an average, they can expect to live five years longer than men."

Additional Information

• Option 2: "As regards" is incorrect because it does not fit the sentence structure or meaning appropriately.

• Option 4: "Turning now" is incorrect because it indicates a shift to a new topic, which is not the case in this sentence.

The correct answer is 'what is more'.

Key Points

• The phrase "what is more" is used to add an additional point or emphasize something in a sentence, making it the most appropriate discourse marker in this context.
• The sentence highlights two aspects: finding a career the speaker loves and getting paid reasonably for it. "What is more" effectively connects these ideas.
• Options 1, 2, and 4 are incorrect as they do not fit the context or purpose of the sentence.

Therefore, the correct answer is Option 3.

Complete Sentence: "The difference is that I have been fortunate to find a career that I love and, what is more, I am getting paid reasonably for it."

Additional Information

• Option 1: "briefly" is incorrect because it implies summarizing, which does not fit the sentence.

• The discourse marker "In general" is used to provide a broad or overall perspective.
• The sentence discusses the Government of India’s policy, which is broadly applicable to improving relations with its neighbours.

Therefore, the correct answer is Option 4.

Additional Information

• Option 1: "Particular" is incorrect as it does not provide a general perspective and changes the meaning of the sentence.
• Option 2: "Knowingly" is incorrect as it implies intentionality, which is not the focus of the sentence.
• Option 3: "Otherwise" is incorrect because it suggests contrast, which is irrelevant in this context.

The correct answer is 'As per reports'.

Key Points

• The discourse marker "As per reports" is appropriate as it suggests that the sentence is based on news, facts, or findings.
• The other options do not fit the context:
• Option 2: Accordingly is incorrect as it indicates a logical result, which does not fit here.
• Option 3: Likewise is incorrect as it is used to indicate similarity, which is not relevant here.
• Option 4: Briefly is incorrect as it is used for summarizing, which is not suitable for the context.

Therefore, the correct answer is Option 1.

The correct answer is Option (4) i.e. QSPR

Key Points

• The part (Q) – "whereas traditional fairy tales" – correctly introduces the contrastive clause and is the natural beginning of the sentence.
• It is logically followed by (S) – "were designed for the entertainment" – which completes the verb phrase and tells us their original purpose.
• Next comes (P) – "of children they also contain deeply embedded" – which links the idea that, apart from entertaining children, these tales have something more.
• Finally, (R) – "moral lessons that are relevant-even for adults" – completes the idea by specifying what they contain, making the full sentence meaningful and grammatically correct.

Thus, the correct rearranged sentence is:

"Whereas traditional fairy tales were designed for the entertainment of children they also contain deeply embedded moral lessons that are relevant-even for adults."

Additional Information

• Option 1 (RPQS): Starting with "moral lessons that are relevant-even for adults" makes the sentence look like a fragment and leaves the contrast and subject unclear at the beginning.
• Option 2 (QSRP): This disturbs the logical flow after stating the purpose; placing "moral lessons" too late makes the sentence feel awkward.
• Option 3 (RPSQ): Beginning with "moral lessons" and then jumping to "of children they also contain deeply embedded" creates a confusing and grammatically unsound opening.
• Option 4 (QSPR): is correct because it maintains a smooth progression: introduction of the tales (Q), their purpose (S), the shift to an additional quality (P), and finally, the nature of that quality (R).

The correct answer is Option (1) i.e. QPSR

Key Points

• The sentence begins with "that sporting activities are an integral part" which is correctly indicated by part (Q).
• Following "Q," the phrase "of school education is an ineluctable truth" (P) logically continues the sequence, explaining the subject of the sentence.
• The next part, "that underscores the learning process and contributes" starts elaborating on the importance of these activities, indicated by (S).
• Ending with "meaningfully towards the overall growth of a student" (R) completes the sentence by describing the significance of the activities.

Therefore, the correct answer is QPSR.

Additional Information

• Option 2 (QSRP): This option starts with "that sporting activities are an integral part that underscores the learning process and contributes" but places "meaningfully towards the overall growth of a student" earlier, which disrupts the logical flow.
• Option 3 (RPSQ): This option starts with "meaningfully towards the overall growth of a student" which is an incorrect start to the sentence.
• Option 4 (QSPR): This option places "of school education is an ineluctable truth" at a later position, disrupting the structure of the sentence.

The correct answer is Option (3) i.e. QSPR

Key Points

• The sentence begins with the phrase "The beneficial outcome of," which is correctly indicated by part (Q).
• Following this, "a virtuous life is peace of mind and contentment" (QS) continues the logical sequence, making it clear what the outcome is.
• The next part, "on account of a life lived" continues the explanation further, which is indicated by (P).
• Ending with "well without retribution or rebuke" (R) completes the sentence by providing additional details about how the life was lived.

Therefore, the correct answer is QSPR.

Additional Information

• Option 1 (SRQP): This option starts with "is peace of mind and contentment," which disrupts the flow and clarity of the sentence.
• Option 2 (SPQR): This option starts with "a virtuous life is peace of mind on account of a life lived," which makes the sentence structure awkward and unclear.
• Option 4 (QSRP): This option starts with "The beneficial outcome of a virtuous life is peace of mind and contentment well without retribution or rebuke," which disrupts the clarity around the description of contentment.

The correct answer is Option (1) i.e. SQRP

Key Points

• The sentence logically begins with "it is widely believed that the parliamentary system differs" which is (S).
• The next part, "from a non-parliamentary system," which is (Q), follows S to continue the comparison logically.
• The next part, "in as much as the former is" (R), explains how the two systems differ.
• Finally, "more representative than the latter" (P) completes the sentence, concluding the comparison.

Therefore, the correct answer is SQRP.

Additional Information

• Option 2 (SPQR): This option creates an illogical sequence starting with "it is widely believed that the parliamentary system differs more representative than the latter," which is incomplete and grammatically incorrect.
• Option 3 (RSPQ): This option begins with "in as much as the former is it is widely believed that the parliamentary system differs," which disrupts the logical flow of the sentence.
• Option 4 (PSRQ): This option starts with "more representative than the latter it is widely believed that the parliamentary system differs," which results in a fragmented and confusing structure.

The correct answer is Option (4) i.e. SRQP

Key Points

• The sentence begins with the conditional clause "when service is done for," which is correctly indicated by part (S).
• Following the preposition "for," the reasons or motives must be listed. Part (R) ("exhibition or for fear of public opinion") logically completes this thought (SR).
• The next part, "it stunts the person offering the same and," starts the main clause by explaining the negative impact of such service, indicated by part (Q).
• Ending with "crushes the spirit behind the service" (P) completes the logical flow by providing the second consequence linked by the conjunction "and" in part (Q).

Therefore, the correct sequence is SRQP.

Additional Information

• Sequence PQRS: This starts with the result "crushes the spirit," making the following parts grammatically disconnected and redundant.
• Sequence RQPS: This starts with the motives "exhibition or for fear..." without a preceding verb or context, leading to an incomplete thought.
• Sequence QPSR: This places the conjunction "and" at the start of the relationship without a preceding clause, making the sentence structure collapse.

The correct answer is 'any further'.

Key Points

• The phrase "any further" is commonly used to denote progress or extent in situations involving comparison or prediction.
• In this context, the sentence compares the progress of the individual in their studies to what was predicted.
• Options 2, 3, and 4 are either incomplete or grammatically unsuitable for the given sentence.

Therefore, the correct answer is Option 1.

Complete Sentence: "It does not look like he is going any further in his studies than what was predicted by his school principal."

Additional Information

• Option 2: "further" is not specific enough in this context and lacks the emphasis provided by "any."
• Option 3: "farther" is typically used for physical distances, making it less appropriate here.
• Option 4: "any farther" is incorrect because "farther" refers to physical distances, not progress in studies.

The correct answer is 'Among'.

Key Points

• The preposition "Among" is used to describe a situation where something happens within a group or in the middle of a set of things or people.
• The sentence implies that the thief made a quiet getaway during the confusion, which involves a group or collective scenario, making "Among" the most appropriate choice.
• Options 2, 3, and 4 are incorrect in this context as they do not fit the grammatical or contextual requirement of the sentence.

Therefore, the correct answer is Option 1.

Complete Sentence: "Among all the confusion the thief made a quiet getaway."

Additional Information

• Option 2: "Amongst" is generally considered an archaic or poetic form of "Among" and is less commonly used in modern English.
• Option 3: "Amidst" is used to describe being surrounded by or in the middle of something but does not fit as naturally in this specific sentence structure.
• Option 4: "Amid" is also used to describe being in the middle of something but is less appropriate in this context than "Among."

The correct answer is 'special'.

Key Points

• The word "special" is the most suitable choice because it describes the expertise or unique skill of the surgeon.
• The sentence emphasizes the surgeon's exceptional ability, which makes "special" the correct option.
• Options 2, 3, and 4 are incorrect as they either do not fit the context or are grammatically inappropriate in this case.

Therefore, the correct answer is Option 1.

Complete Sentence: "The intricate operation on the patient required the expertise of a/an special surgeon."

• Option 2: "especial" is not commonly used in modern English and does not fit the context.
• Option 3: "specialist" is incorrect because it would imply a specific field of specialization rather than the general meaning of expertise.
• Option 4: "specialised" is incorrect because it implies a specific focus rather than a general sense of expertise.

The correct answer is 'fewer than'.

Key Points

• The phrase "fewer than" is used when referring to countable plural nouns.
• In this sentence, "students" is a countable noun, so "fewer" is required to indicate a smaller quantity. Additionally, "than" is the correct conjunction used for making comparisons.
• Options 1, 3, and 4 are grammatically incorrect in this context.

Therefore, the correct answer is Option 2.

Complete Sentence: "There are fewer than thirty students inside the classroom at any time."

Additional Information

• Option 1: "less than" is incorrect because "less" is properly used with uncountable or singular mass nouns (e.g., less water, less time).
• Option 3: "less then" is incorrect due to the misuse of "less" with a countable noun, and because "then" is an adverb of time, not a conjunction for comparison.
• Option 4: "fewer then" is incorrect because "then" is used to indicate time or sequence, whereas "than" is necessary to make a numerical comparison.

The correct answer is 'stranded'.

Key Points

• The word "stranded" refers to being left helpless or in a position from which one cannot leave.
• In the given sentence, the vehicles are immobile due to a sudden landslide, making "stranded" the most appropriate choice.
• Option 1: "stationery" is incorrect because it refers to writing materials; the term for being immobile is "stationary."
• Option 2: "stationed" is incorrect because it implies that the vehicles were intentionally placed or assigned to a spot, which is not the case here.
• Option 4: "straggle" is incorrect as it refers to moving slowly or being spread out, which does not fit the scenario.

Therefore, the correct answer is Option 3.

Complete Sentence: "There are many stranded vehicles on the highway due to a sudden landslide."

Additional Information

• Option 1: "stationery" refers to paper, envelopes, and other office materials.
• Option 2: "stationed" is typically used to describe someone or something assigned to a specific location for a purpose, which does not align with the context here.
• Option 4: "straggle" describes slow or scattered movement, which does not fit the description of vehicles being stuck.

Calculation

Given focal length of the concave lens, f = −0.5 m.

Power of a lens is defined as:

P = 1 / f

Substituting the value of f,

P = 1 / (−0.5)

P = −2.0 D

The negative sign indicates that the lens is concave.

Therefore, the correct answer is Option 4.

Calculation

This situation involves three mutually perpendicular directions:

⇒ direction of magnetic field

⇒ direction of current

⇒ direction of force (motion) on the conductor

Fleming’s left-hand rule is specifically used to determine the direction of force experienced by a current-carrying conductor in a magnetic field.

Right-hand thumb rule is used to find the direction of magnetic field due to current, not force.

Fleming’s right-hand rule applies to generators, and Hund’s rule is related to atomic structure.

Therefore, the correct answer is Option 2.

Calculation

One parsec is defined as the distance at which one astronomical unit subtends an angle of one arcsecond.

Numerically,

⇒ 1 parsec ≈ 206,265 astronomical units (A.U.)

Expressing this value in scientific notation:

⇒ 206,265 ≈ 2 × 10⁵

Hence,

⇒ 1 parsec ≈ 2 × 10⁵ A.U.

Therefore, the correct answer is Option 3.

Calculation

According to the second law of motion, the net force acting on a body is related to its motion.

⇒ Force is proportional to acceleration.

⇒ Force acts in the same direction as acceleration.

⇒ Force equals the time rate of change of momentum.

Momentum is given by:

⇒ p = m × v

Hence, force depends on how momentum changes with time, not on momentum itself.

Therefore, the statement saying that force is proportional to momentum is incorrect.

Therefore, the correct answer is Option 4.

Calculation

Initial temperature, T₁ = 310 K

Final temperature, T₂ = 340 K

Increase in temperature = T₂ − T₁ ⇒ 340 − 310 = 30 K

Temperature difference remains the same in Kelvin and Celsius.

Initial temperature in Celsius ⇒ 310 − 273 = 37°C

Final temperature in Celsius ⇒ 340 − 273 = 67°C

Increase in Celsius ⇒ 67 − 37 = 30°C

Thus, the temperature increase is 30°C.

Calculation

Work done by gravity depends only on the vertical displacement.

Work = m × g × h

⇒ m is the mass of the body

⇒ g is acceleration due to gravity

⇒ h is the vertical distance between initial and final positions

Gravity is a conservative force.

⇒ Work done is independent of the path followed ✔

⇒ Work done depends only on vertical separation ✔

⇒ Work done does not depend on the path ✔

⇒ Work done is zero for horizontal displacement ✔

The statement saying that work done depends on the path followed is incorrect.

Therefore, the correct answer is Option 3.

Calculation

Pressure is a scalar quantity.

⇒ It has magnitude only, not direction.

Pressure in a liquid increases with depth.

⇒ It does not decrease as we go deeper.

According to Newton’s third law:

⇒ Action and reaction forces act on different bodies, not on the same object.

The SI unit of pressure is pascal.

⇒ 1 pascal = 1 N/m².

Hence, the statement that pascal and N/m² represent the same unit is correct.

Therefore, the correct answer is Option 4.

Calculation

X-rays have wavelengths in the range of about 0.01 nm to 10 nm.

1 nm lies within this X-ray wavelength range.

10 nm lies at the boundary and generally falls in the ultraviolet region.

100 nm and 300 nm correspond to ultraviolet radiation, not X-rays.

Hence, among the given options, 1 nm represents X-ray radiation.

Therefore, the correct answer is Option 1.

Explanation:

In a telescope, the objective lens is meant to collect light from distant objects.

To gather sufficient light, it must have a larger aperture.

To properly focus nearly parallel rays from distant objects, it requires a larger focal length.

The eyepiece, in contrast, has a smaller focal length and smaller aperture for magnification.

⇒ Compared to the eyepiece, the objective lens has both a larger focal length and a larger aperture.

Therefore, the correct answer is Option 1.

Calculation:

The energy of a photon is given by the relation E = h × f.

Here, E represents energy, f represents frequency, and h is Planck’s constant.

The dimensional formula of energy is [M L² T⁻², while the dimensional formula of frequency is [T⁻¹].

From the relation h = E / f

⇒[h] = [M L² T⁻²] / [T⁻¹]

⇒ [h] = [M L² T⁻¹]

Angular momentum also has the dimensional formula [M L² T⁻¹], which matches that of Planck’s constant.

Therefore, the correct answer is Option 2.

Calculation:

Work done by a force depends on the relative direction of force and displacement.

The relation for work done is W = F × d × cos(θ), where θ is the angle between force and displacement.

When the displacement is perpendicular to the direction of force, θ = 90°.

cos(90°) = 0

⇒ W = F × d × 0

⇒ W = 0

This shows that no work is done when force acts perpendicular to the displacement.

Therefore, the correct answer is Option 3.

Explanation:

The magnetic field inside a very long current-carrying solenoid is considered.

According to Ampere’s circuital law, the magnetic field inside a solenoid depends on the current and the number of turns per unit length.

The relation is B = μ₀ × n × I.

Here, μ₀ is the permeability of free space, n is the number of turns per unit length, and I is the current.

For a very long solenoid, end effects are negligible.

⇒ The magnetic field remains the same at all points inside the solenoid.

This shows that the magnetic field inside a very long solenoid is uniform.

Therefore, the correct answer is Option 1.

Explanation:

The temperature to be measured is −250°C, which lies in the extremely low temperature range.

Mercury thermometers are unsuitable because mercury freezes at about −39°C.

Clinical thermometers are limited to human body temperature ranges and cannot measure extreme cold.

Alcohol thermometers are also unsuitable since alcohol freezes near −114°C, which is much higher than −250°C.

Thermocouple-based thermometers are designed to measure very wide temperature ranges, including extremely low temperatures.

⇒ Only a thermocouple can reliably measure −250°C.

Therefore, the correct answer is Option 4.

Explanation:

The quantity of heat required to change the state of a substance without any change in temperature is considered.

When unit mass of a liquid changes into vapour at constant temperature, the heat supplied does not raise temperature but is used for phase change.

This heat is defined as specific latent heat.

Specific heat relates to temperature change, thermal capacity refers to total heat required for a body, and heat energy is a general term.

⇒ The given definition matches specific latent heat.

Therefore, the correct answer is Option 2.

Explanation:

The condition described refers to the temperature at which a liquid’s vapour pressure equals the surrounding atmospheric pressure.

At this stage, bubbles of vapour form throughout the liquid and rise to the surface.

This characteristic temperature is defined as the boiling point.

Melting point relates to solid–liquid change, while the other options do not describe vapour pressure equality.

⇒ The given definition corresponds to the boiling point.

Therefore, the correct answer is Option 2.

Explanation:

Surface tension depends on the cohesive forces between molecules at the surface of a liquid.

With an increase in temperature, molecular kinetic energy increases.

This weakens the cohesive forces acting at the surface.

⇒ Surface tension decreases as temperature increases.

It does not remain constant, nor does it increase with temperature.

The change is not symmetric for both increase and decrease in temperature.

Therefore, the correct answer is Option 2.

Explanation:

The sinking or floating of a body in water depends on the comparison of densities.

If the density of a body is greater than the density of water, the buoyant force is insufficient to support it.

Density condition for sinking is expressed as:

ρ_body > ρ_water

⇒ When the density of water is less than the density of the body, the body sinks.

If densities are equal, the body remains suspended, and if the body’s density is lower, it floats.

This directly matches the stated condition.

Therefore, the correct answer is Option 2.

Explanation:

When a fielder catches a fast-moving ball, the ball’s momentum must reduce to zero.

According to the impulse–momentum relation, impulse equals change in momentum.

Impulse = Force × Time

For a fixed change in momentum, increasing the time of contact reduces the force.

⇒ Lower force results in smaller acceleration of the ball.

By pulling the hands backward, the fielder increases contact time.

This reduces impact force and prevents injury while catching the ball safely.

Therefore, the correct answer is Option 1.

Explanation:

The apparent raising of the bottom of a water-filled tank is an optical effect.

When light travels from water to air, its speed changes.

This causes the light rays to bend at the boundary between the two media.

⇒ The bending of light leads to an apparent shift in the position of the tank bottom.

This phenomenon is known as refraction of light.

Hence, the bottom appears raised due to refraction.

Therefore, the correct answer is Option 2.

Explanation:

The term SONAR is an acronym related to the use of sound waves.

SONAR stands for Sound Navigation and Ranging.

It is used to detect, locate, and determine the distance of objects under water.

⇒ The name reflects its function of navigation and ranging using sound.

Other expansions do not match the accepted scientific meaning.

Therefore, the correct answer is Option 3.

Explanation:

Electromagnetic waves can be arranged in order of increasing wavelength.

The general order is: Gamma rays < X-rays < Ultraviolet < Visible light < Infra-red < Microwaves < Radio waves.

From this sequence, X-rays and ultraviolet have much shorter wavelengths.

Infra-red has a longer wavelength than visible light but is still shorter than microwaves.

⇒ Among the given options, microwaves possess the longest wavelength.

Therefore, the correct answer is Option 3.

Explanation:

Static conditions refer to a situation where electric charges remain at rest.

In an insulator, charges are not free to move and hence remain localized where they are placed.

This allows an insulator to retain electric charge under static conditions.

In a conductor, charges are free to move and redistribute themselves, making it difficult to maintain localized static charge.

⇒ Under static conditions, an insulator can be charged.

Therefore, the correct answer is Option 1.

Explanation

A person can see nearby objects clearly but cannot see distant objects distinctly.

This visual behavior corresponds to Myopia.

In Myopia, light rays focus before reaching the retina ⇒ distant objects appear blurred while near objects remain clear.

The given condition matches this characteristic.

Therefore, the correct answer is Option 3: Myopia.

Explanation

The energy of a system is always conserved when no exchange of energy or matter occurs with the surroundings.

An isolated system satisfies this condition.

In such a system, total energy remains constant over time ⇒ energy conservation is guaranteed.

Non-isolated systems may exchange energy, so conservation is not ensured for the system alone.

Therefore, the correct answer is Option 1: Isolated only.

Explanation:

A ball of mass M is thrown upwards from point A, reaches the highest point B, and returns to A.

At point A, the ball has kinetic energy due to its velocity.

At point B, the velocity becomes zero ⇒ kinetic energy is zero, and the ball has only potential energy due to height.

According to conservation of energy:

Total energy at A = Total energy at B

⇒ K.E. at A = P.E. at B

This energy relation is correct for the motion.

Therefore, the correct answer is Option 1.
