✅ The correct answer is 'She is not reading a book.' because we place 'not' right after the auxiliary verb ('is') without changing the main verb form.
The dog barks at strangers. (change into negative)

They had a large collection of antique books. (change into negative)
✅ The correct answer is 'They did not have a large collection of antique books.' When had expresses possession in the past, it functions as a main verb. To form the negative of a main verb in simple past tense, we use did not followed by the base form of the verb.

When transforming a statement with 'have to' into a question, we use the auxiliary verb 'do' (for plural subjects or I/you) or 'does' (for singular third person subjects).

I have a beautiful garden at home. (change into negative)
✅ The correct answer is 'I do not have a beautiful garden at home.' When have expresses possession or ownership, it functions as a main verb, not an auxiliary. Therefore, we use do not to form the negative, just as we would with any other main verb in simple present tense.
They have to attend the meeting every Monday. (Change into negative)
✅ The correct answer is 'They don't have to attend the meeting every Monday.' When transforming sentences with 'have to' into negative form for plural subjects, we use 'do not' or 'don't' followed by 'have to.' The structure is subject + don't + have to + rest of sentence. This follows the rule that 'have to' requires the auxiliary 'do' to form negatives.
Not many people understand quantum physics. (Change into equivalent with 'few')
✅ The correct answer is 'Very few people understand quantum physics.' When transforming 'not many' into an equivalent expression using 'few,' we use 'very few.' Both phrases express the same idea of a small quantity, but they use different grammatical constructions to achieve this meaning.

Any of these methods will work for solving the problem. (change into negative)
✅ The correct answer is 'None of these methods will work for solving the problem.' When transforming 'any of' to negative, we use 'none of' to indicate that not a single one of the methods will work. With modal auxiliaries like 'will', the verb form remains the same regardless of whether the subject is singular or plural.

The transformation follows this pattern: 'some of' → 'none of' with appropriate verb agreement.
Most of the participants have completed the survey. (change into negative)
✅ The correct answer is 'None of the participants has completed the survey.' When changing 'most of' to negative, we use 'none of' to completely negate the statement.

They always arrive on time for meetings. (change into negative)
✅ The correct answer is 'They are never late for meetings.' When transforming sentences with 'always' to negative, we use 'never' and often need to restructure the sentence using antonyms. Here, 'always arrive on time' becomes 'never late' to maintain the same basic meaning.
We had lunch at the new restaurant yesterday. (change into negative)
✅ The correct answer is 'We did not have lunch at the new restaurant yesterday.' When had refers to consuming a meal, it functions as a main verb. To form the negative of a main verb in simple past tense, we use did not followed by the base form of the verb.

✅ The correct answer is 'She doesn't have to complete the assignment by tomorrow.' When transforming sentences with 'has to' into negative form, we use the auxiliary verb 'does' + 'not' + 'have to.'
