The correct option is (b).

The correct one-word for the given group of words is (b) Scurry.

Explanation: “Scurry” means to move quickly with short, hurried steps, usually because of fear, urgency, or excitement. It suggests fast movement in a slightly panicked or rushed manner. (Hindi meaning: हड़बड़ी में छोटे-छोटे कदमों से तेज़ चलना/भागना)

Example: The mice scurried into the holes as soon as the lights were turned on.

Meanings of the given other options:

• Option A: Squid – a sea animal with a soft body and tentacles (Hindi meaning: स्क्विड/समुद्री जीव)
• Option C: Loiter – to stand or move slowly without purpose; to linger (Hindi meaning: आवारा घूमना/बेकार रुकना)
• Option D: Crawl – to move slowly on hands and knees or close to the ground (Hindi meaning: रेंगना)

So the correct answer is (b)

Correct Answer is: To use disproportionate force or expense to overcome a minor problem

• Given phrase – “A sledgehammer to crack a nut”:

• This phrase means using a very strong, heavy, or expensive method to deal with a very small or simple problem.

• In other words, the action taken is far greater than what the situation actually requires.

• (Hindi meaning: छोटी समस्या के लिए जरूरत से ज्यादा बल/खर्च लगाना; तोप से मक्खी मारना)

• Example: Hiring a full legal team for a minor complaint is like using a sledgehammer to crack a nut.

• Correct meaning – Option (c):

• “To use disproportionate force or expense to overcome a minor problem” exactly matches the sense of the phrase because a sledgehammer is far too powerful for cracking a small nut.

• Other related idioms/phrases:

• Make a mountain out of a molehill – exaggerate a small issue (Hindi: राई का पहाड़ बनाना)

• Overkill – more action than necessary (Hindi: जरूरत से ज्यादा करना)

• To kill a fly with a cannon – excessive method for a tiny task (Hindi: तोप से मक्खी मारना)

• Meanings of other options (why they are incorrect):

• (a) “a lot of options” – unrelated to using excessive force.

• (b) “person of very high stature” – unrelated meaning.

• (d) “performing a task against demeanour” – does not match the idea of excessive measures.

So the correct answer is (c).

Correct Answer is: Authorities thought the suspect had been staying in a remote lodge before they arrested him.

Explanation: The given sentence uses an impersonal passive structure: “The suspect was thought ...”. In active voice, we must introduce an appropriate doer (agent) such as people/authorities/police as the subject, and convert the passive reporting verb into an active reporting verb.

The phrase to have been staying indicates an action that was in progress before another past action (arrest). In active voice, this is best expressed using past perfect continuous: had been staying.

Also, “before being arrested” must become an active clause: before they arrested him.

Structure used:

• Passive reporting: Subject + was/were thought + to have + V3 / to have been + V-ing
• Active reporting: People/Authorities + thought + (that) + subject + had been + V-ing

Why other options are incorrect:

• A: Wrong meaning because it makes the suspect the thinker, which changes the sense.
• B: “stayed” does not correctly match the continuous idea “had been staying” and also misses the arrest clause.
• C: This remains passive/impersonal; it is not converted into active voice.

So the correct answer is (d)

Correct Answer is: QSRP

• Explanation: The opening part is “In August 2013,” which must be followed by a proposal/decision statement (what happened in that time).

• The most logical continuation is the clause that begins the proposal: “it was proposed that…” which is part Q.

• Step-by-step arrangement:

• Q. it was proposed that France may halve the number of Rafales

– This correctly completes the time phrase “In August 2013,” and introduces the main idea.

• S. to be delivered over the next six years for a total of 26 aircraft

– This gives the delivery plan and total number, directly linked to “the number of Rafales”.

• R. to be delivered during this period

– “this period” clearly refers back to “over the next six years”, so R must come after S to maintain reference clarity.

• P. procurements have been viewed as critical to maintain production

– This is an explanatory concluding statement giving the reason/importance of procurements for maintaining production, hence it fits at the end.

So the correct answer is (c).

Correct Answer is: go functional

Detailed explanation of error:

· The time expression “last Monday” requires Simple Past.

· With a singular subject “schedule”, the verb must agree and reflect the past: “went (or became) functional” / “went into effect”.

· The phrase “go functional” is ungrammatical; correct forms: “went functional,” “became functional,” or more idiomatically “went into effect.”

Grammatical rule used:

· Simple Past (V2) is used for completed actions at a definite time in the past (e.g., yesterday, last week/Monday, in 2023).

· Subject–Verb Agreement: singular subject → singular verb form (in past, use V2).

Example:

· The policy went into effect last Monday.

· The system became functional yesterday.

Information booster:

· In formal English, “come/come into force” and “go into effect” are common legal/administrative collocations for rules, schedules, and policies.

Correct Answer is: were discussing the presentation

In this sentence, the subject is "The group". The word group is a collective noun and is treated as singular when the group acts as a single unit.

The phrase "along with the principal" is only an additional phrase and does not change the number of the subject. Therefore, the verb must agree with the singular subject group.

Hence, "were discussing" is incorrect here; it should be "was discussing".

Correct form: The group of students, along with the principal, was discussing the presentation for the annual function.

Grammatical rule used: When the main subject is singular, phrases like along with, together with, as well as, in addition to do not affect subject-verb agreement.

Example: The captain, along with his teammates, is ready for the match.

So the correct answer is (c)

Correct Answer is: Offer something to someone who already has plenty of it

The idiom “Sell ice to an Eskimo” refers to trying to sell something to a person who already has an abundance of it or does not need it, which highlights an unnecessary or absurd sales attempt. (Hindi idiom meaning: जिसके पास पहले से बहुत है, उसे वही चीज़ बेचना).

Explanation:

• Eskimos (Inuit people) are associated with extremely cold regions where ice is naturally abundant.
• Selling ice there would be pointless because the buyer already has plenty of ice.
• Hence, the meaning matches option (A): offering something to someone who already has plenty of it.

Example: Trying to sell umbrellas during a drought is like selling ice to an Eskimo.

Other related idioms and meanings:

• Carry coals to Newcastle – to take something to a place where it is already plentiful.
• Preach to the choir – to give advice or information to people who already agree or know it.
• Teach fish to swim – to try to teach someone something they already know well.

So the correct answer is (a)

Correct Answer is: Resplendent

Luminous means giving off light, shining, or glowing brightly; it can also mean intellectually bright or clear. (Hindi meaning: चमकीला / प्रकाशमान)

Example (given word): The luminous moon lit up the entire landscape.

The best synonym among the options is resplendent, which means shining brilliantly, dazzling, or splendidly bright. (Hindi meaning: दीप्तिमान / अत्यंत चमकदार) It directly matches the sense of “luminous”.

Example (correct word): She appeared resplendent in her traditional attire under the stage lights.

Synonyms of luminous: radiant, shining, brilliant, resplendent.

Antonyms of luminous: dark, dim, gloomy, opaque.

Meanings of other options:

• Option (A) Gloomy: dark; depressing (Hindi: उदास / अंधकारमय).
• Option (B) Murky: dark and dirty; unclear (Hindi: धुंधला / मटमैला).
• Option (C) Opaque: not transparent; not letting light pass through (Hindi: अपारदर्शी).

So the correct answer is (d)

Correct Answer is: RPSQ

Correct sequence: R → P → S → Q

• (R) is the best opening sentence because it introduces the main idea: people are focusing on reducing their carbon footprints.
• (P) logically follows because it gives one way to reduce carbon footprints (using public transportation instead of private cars).
• (S) must come after (P) because the phrase “This shift” clearly refers to the shift mentioned in (P), i.e., shifting from private cars to public transportation. It also adds the benefit of reducing traffic congestion.
• (Q) comes at the end because it begins with “Additionally”, which adds another supporting method (renewable energy) after already giving one method and its benefit.

Thus, the coherent paragraph first states the global focus, then provides one method, explains the benefit of that method, and finally adds another method.

So the correct answer is (a)

The correct option is (a).

To form a coherent paragraph, we must start with the definition of the topic and then proceed from the general concept to specific components and finally to benefits.

• Sentence (2) should come first: It introduces the topic “Object-Oriented Programming (OOP)” and defines it as a paradigm built around objects. This is the proper opening for the paragraph.
• Sentence (1) follows: After introducing OOP and objects, it explains a core concept of the paradigm—the “class”—which is essential to creating objects. This is a natural next step because it expands the concept.
• Sentence (3) comes next: The pronoun “This” refers back to the concept just explained (OOP using objects/classes). It states the consequence/utility: developers can define structure and behavior in an object-based manner.
• Sentence (4) should be last: It provides a concluding benefit: mirroring real-world entities makes large systems easier to maintain and debug. Benefits typically appear after explanation.

Therefore, the correct sequence is 2, 1, 3, 4, i.e., option (A).

So the correct answer is (a)
