The correct answer is The telephone has been ringing for an hour.

Key Points

• Singular subject agrees with singular verb.
• 'Has' is used with singular subjects while 'have' is used with plural subjects.
• Here, 'telephone' is a singular subject.
• Thus, has is the correct usage.

Thus, option 4 is the correct alternative.

Correct Sentence: The telephone has been ringing for an hour.

The correct answer is "Quick".

Key Points

Let's understand the meaning of the correct word:

• The most appropriate word to fill in the blank is "Quick".
• It means done or occurring with rapid speed or promptness.
  • For Example - The cheetah is known for its quick speed, making it the fastest land animal.

Therefore, the correct answer is "Option 3".

Correct Sentence: Let me have a quick word with you.

Additional Information

Let's understand the meanings of the other given options:

• Fast - Moving or being able to move quickly; having a high rate of motion or speed.
• Prompt - Done without delay; on time; quick to act or respond.
• Swift - Moving or able to move quickly; rapid; fast.

The correct answer is 'She likes ice-cream'.

Key Points

• The original sentence 'Ice-cream is liked by her.' is in passive voice.
• To convert a sentence to active voice, we identify the subject, verb, and object.
  • In this case, 'she' is the subject, 'likes' is the verb, and 'ice-cream' is the object.
• The structure of an active voice sentence generally follows the format of subject-verb-object.
• Only the option 'She likes ice-cream.' correctly transforms the sentence into active voice without changing the meaning of the original sentence.

Therefore, the correct answer is 'Option 1'.

Additional Information

• Option 2) 'She like to eat ice-cream.' is incorrect because it changes the verb tense and adds unnecessary detail not present in the original sentence.
• Option 3) 'She like ice-cream.' is grammatically incorrect due to the verb agreement. It should be 'likes' to match the third person singular subject 'She'.
• Option 4) 'She loves ice-cream.' changes the verb from 'likes' to 'loves', which can imply a stronger preference than originally stated, thereby altering the meaning subtlety.

The correct answer is 'Option 1'.

Key Points

• The error in the sentence is in the phrase "gaze became distinctly coldest".
• In English, we don't often use the superlative form ("coldest") with "distinctly" or any other adverbs of degree. It would be more appropriate to say "gaze became distinctly cold" or "became the coldest", without the adverb.
• In the correct form, "gaze became distinctly cold", the adverb "distinctly" modifies the adjective "cold", intensifying the degree to which his gaze became cold.
• In the other form, "gaze became the coldest", "the coldest" is a superlative adjective, showing that his gaze is at the highest degree of coldness, compared to other references (if any) in the given context.

Therefore, the corrected sentence would be: "Professor Murli's eyebrows rose a little higher and his gaze became distinctly cold" or "gaze became the coldest".

Additional Information

• "Professor Murli's eyebrows" (Option 3): This segment of the sentence contains no grammatical error. It is grammatically correct to refer to a person’s physical features in this way.
• "rose a little higher and his" (Option 4): This segment is also grammatically correct. It means Professor Murli's eyebrows moved upwards to a slightly greater height, which is often a sign of surprise or disbelief.

The correct answer is: 'Option 4: change (alter)'

Key Points

• 'Change' (परिवर्तन/बदलाव) in this context refers to making something different or the act of becoming different.
  • Example: "I decided to change my hairstyle."
• 'Change (alter)' (परिवर्तन/बदलाव), the correct word, essentially conveys the message of modifying or transforming something. An example might be: "She decided to change her diet to feel healthier."

Therefore, the correct answer is 'Option 4: change (alter)'

Additional Information

• 'Change (loose money)' (छुट्टा/छिल्लर) refers to coins as opposed to paper currency.
• 'Change (transfer)' (स्थानांतरण/ट्रांसफर) refers to a shift or move from a particular place.
• 'Change (switch)' (स्विच/बदल) refers to replacing one thing with another.

The correct answer is 'Adversity happens to everyone.'

Key Points

• Among the given options, only in Option 1 the spelling of 'Adversity' is correct.
• It means 'difficulties or problems'. (कठिनाइयाँ, समस्‍याएँ, मुसीबतें; विपत्तियाँ)
  • Example: He thinks he has come through a lot of stress and adversity in his life.

Correct Answer: Adversity happens to everyone.

The correct answer is 'Samay had not wanted to believe that one of his sons betrayed the rest of the Council'.

Key Points

• The sentence uses the past perfect tense correctly with "had not wanted" to express action that happened before a point in the past.
• The verb "betrayed" is consistent with the tense of the sentence – past perfect.
• The noun "sons" is used correctly indicating that Samay has more than one son.

Therefore, the correct answer is Option 3.

The correct answer is "The crime has not been committed by him."

Key Points

• In passive voice, the object of the active sentence becomes the subject of the passive sentence.
  • Example: I am loved by him.
• Now, in the given sentence, 
  • The auxiliary verb "has" changes to "has been" in the passive voice.
  • The past participle form of the main verb "commit" is "committed."
  • The preposition "by" is used to indicate the doer of the action in the passive voice.
• Thus, the sentence in passive voice will be: The crime has not been committed by him.

Hence, the correct answer is option 4.

Here the correct answer is Explanation.

Key Points

• The word "description" refers to the act of providing details, characteristics, or an account of something. It involves giving a verbal or written representation of a person, object, event, or concept. "Description" helps create a clear and vivid image or understanding of the subject being described.
• Examples of using "description" in sentences:
  • She provided a detailed description of the crime scene to the police.
  • The novel was praised for its rich and vivid descriptions of the exotic locations.
• ​Now let's examine the other options and their meanings:
• Obscurity: "Obscurity" refers to the state of being unknown, unclear, or lacking visibility. It is the opposite of clarity and can denote being hidden or difficult to understand.
  • Example: The author's writing style is known for its deliberate obscurity, leaving readers to interpret the meaning for themselves.
• Creation: "Creation" refers to the act of making or producing something new. It implies bringing into existence or forming something that did not previously exist.
  • Example: The artist's latest creation was a stunning sculpture made from recycled materials.
• Madness: "Madness" refers to a state of mental instability or irrational behavior. It denotes a lack of reason, coherence, or sanity.
  • Example: The chaotic scene at the protest descended into madness as clashes between protesters and police escalated.
• While options 1, 2, and 4 have their own meanings, they do not serve as appropriate synonyms for "description" in the given context.
• Only option 3, "Explanation," aligns with the meaning of "description" by emphasizing the act of providing information, clarifying details, or offering an account.
• Therefore, the correct answer is option 3, "Explanation."

The correct answer is: Millennium.

Key Points

• The word "Millennium" means a period of one thousand years, especially when calculated from the traditional date of the birth of Christ. (सहस्राब्दी)
  • Example: The year 2000 was celebrated as the beginning of a new millennium.

Therefore, the correct answer is: Millennium.
