Q3: Read the following paragraph and answer the following question

(a) 
Gruesome              
(b) 
Horrible

Ans: (c)
Explanation: Harrowing describes something distressing or painfully upsetting. The antonym is attractive, which means pleasing to the eye or appealing. Options (a) and (b) are close in meaning to harrowing, while (d) 'adorable' is similar to attractive but 'attractive' is the most direct opposite in this context.

Q4: Read the following paragraph and answer the question that follows,
Most of the human history has been the Paleolithic period or the old stone age. There is also a mesolithic period that comes about 20000 years ago. The exponential change in the development of the human civilization, however, came in the recent few centuries.
The word in the bold can be replaced by the following word without changing the meaning of the sentence.
(a) 
Tremendous              
(b) Fast                 
(c)
Great             
(d) 
Increasing

Ans: (a)
Explanation: Here exponential is used to describe a very large, rapid increase. Tremendous conveys a similar sense of very great extent or magnitude and is the best replacement among the options. While (b) 'fast' and (d) 'increasing' indicate speed or growth, they do not fully capture the large-scale intensity implied by 'exponential'.

Q5: What is the most appropriate antonym for the given word?
Extremist
(a) Absolutist
(b) Fanatic
(c) Zealot
(d) Radical
(e) Moderate

Ans: (e)
Explanation: An extremist holds views that are far from the centre and often advocates extreme measures. A moderate holds reasonable, balanced opinions and avoids extreme positions. Thus, 'moderate' is the clear antonym. Example: Extremists pushed for uncompromising changes, while moderates sought gradual reforms.

  • Key Points 
  • "Extremist" is a person who holds extreme or fanatical political or religious views, particularly one who resorts to or advocates extreme action.
    • Example - The extremist views of the group have led to several violent outbursts in the area.
  • "Moderate", on the other hand, is a person who holds views that aren't extreme; they are generally reasonable and balanced.
    • Example - His moderate approach to the situation enabled a smooth negotiation and solution.
  • Hence, the option that is opposite in meaning to "Extremist" is Moderate.

Therefore, the correct answer is 'Option (e)'.

Q6: What is the most appropriate antonym for the word?
Dismantle
(a) Construct
(b) Obfuscate

Ans: (a)
Explanation: Dismantle means to take something apart or to break it down into pieces. Construct means to build or assemble parts together. These two words are direct opposites in the context of building versus taking apart. Example: They dismantled the old shed and then constructed a new one in its place.

  • Key Points
  • "Dismantle" means to take apart, disassemble, or tear down.
    • Example - They had to dismantle the engine to find the problem.
  • "Construct" means to build or form something by putting parts together.
    • Example - They will construct a new school building next year.

Precarity
(a) Lithe
(b) Stasis
(c) Desuetude
(d) Ubiquity
(e) Quiescence

Explanation: Precarity refers to a state of instability, uncertainty or insecure circumstances. Stasis means a stable condition without change or movement and therefore serves as an antonym. Example: The precarity of his job meant constant worry, while stasis would imply steady employment.

  • Key Points 
  • 'Precarity' is the state of being precarious or uncertain.
    • Example - The precarity of his employment meant that he never knew if he would still have a job the following week.
  • 'Stasis' is a state or condition in which things do not change or progress, implying a sense of balance or stability.
    • Example - The nation is currently in a state of economic stasis.

Therefore, the correct answer is 'Option (b)'.

Q8: What is the most appropriate synonym for the given word?
Assailant
(a) Tormentor
(b) Poltroon
(c) Altruist
(d) Philanthropist
(e) Verbose

Ans: (a)
Explanation: An assailant is someone who attacks another person. A tormentor is someone who causes pain or distress to another, often by attacking or harassing. Because both imply causing harm or attack, tormentor is the closest synonym. Example: The police searched for the assailant who had tormented the victim.

  • Key Points
  • "Assailant" is a person who physically attacks another. It implies someone who initiates a hostile action.
    • Example - The police are still on the lookout for the assailant involved in last night's brawl.
  • "Tormentor" is someone who causes great physical or mental pain to others. Just like an assailant, a tormentor instigates harm or suffering.
    • Example - Despite being seen as a friendly face, behind closed doors, he was a tormentor to his family.
  • Hence, the option that is similar in meaning to the given word "Assailant" is 'Tormentor'.

Therefore, the correct answer is 'Option (a)'.

Disconsolate
(a) Mercurial
(b) Despondent
(c) Candid
(d) Frivolous

  • Key Points
  • "Disconsolate" means without any comfort or consolation, extremely unhappy or dejected.
    • Example - The team was disconsolate after losing the championship match.
  • "Despondent" means in low spirits from loss of hope or courage.
