The correct answer is option 1 i.e. A.

The error is in part (A) "Some students must bring."

The use of "some" implies that not all students are required to bring their textbooks to class, which could be incorrect. The sentence should indicate that all students are required to bring their textbooks.

So, the correct sentence would be "All students must bring their textbooks to class every day, and they should make sure that they are in good condition."

The correct answer is option 2 i.e. 2.

• The error is in part 2.
• The correct order of determiners for adjectives in English is "opinion - size - age - shape - colour - origin - material."
• Therefore, the correct order of determiners in this sentence should be "a beautiful antique wooden French chair."

So the correct sentence is: She had just bought a beautiful antique wooden French chair at the auction.

The correct answer is option 4 i.e., No improvement required.

• There is no error in the given sentence, thus, no improvement is required.
• Past perfect tense, used to indicate an action that was completed before another point in time (even if unstated).
• 'Herself' is the reflexive pronoun, correctly used here.

The correct answer is option 4 i.e. Jyoti has forgotten the keys.

• To convert the given sentence into the active voice, we need to identify the subject and the object of the sentence, and then rearrange the sentence to make the subject the doer of the action, and the object the receiver of the action.
• In the given sentence, the subject is "keys" and the object is "Jyoti".
• The sentence is in the passive voice, which means that the object is the doer of the action, and the subject is the receiver of the action.
• To convert it to the active voice, we need to make 'the subject' the doer of the action.

Thus, the most appropriate active form of the given sentence is:

Jyoti has forgotten the keys.

The correct answer is option 4 i.e. Grievance

Incorrect spellings: Greivance, Grievanse, Grievence

Correct spelling: Grievance

Meaning: A complaint or protest

Example: The workers aired their grievance to the manager.

Hence, the chosen option is correct.

The correct answer is option 3 i.e. Entrepreneur.

The CORRECTLY spelt word is Entrepreneur which means a person who makes money by starting or running businesses, especially when this involves taking financial risks.

Hence, the chosen option will be correct.

The correct answer is option 1 i.e. Mysterious.

• The word 'Uncanny' means 'strange or mysterious, especially in an unsettling way'.
• The most appropriate synonym of the given word is 'Mysterious' which means 'strange, not known, or not understood'.

Hence, the correct answer is Mysterious.

The correct answer is option 1 i.e. Insult.

• "Flatter" means to praise or compliment someone excessively.
• An "insult" is a disrespectful or offensive remark or action intended to harm someone's feelings, dignity, or self-esteem.

The correct answer is option 2 i.e. Exclude.

"Encircle" means to surround or form a circle around something, while "exclude" means to leave out something.

Therefore, "exclude" serves as an appropriate antonym to "encircle" because it represents the opposite action of deliberately keeping something out or not surrounding it.

The correct answer is option 4 i.e. Terminal.

"Initial" refers to something that occurs at the beginning or introductory stage of a process, while "terminal" refers to something that occurs at the end or final stage.

Meaning of the other options:

Trivial: insignificant or unimportant.

Fractional: very small or relating to a fraction.

Inaugural: marking the beginning or first of a series.
