Hence, option C is the correct answer.

The underlined part is grammatically incorrect. The given sentence does not need any modal, thus ‘could’ should be eliminated. Also, the tense used is simple past (did + V1 or only V2), thus ‘did’ should be used which is given in option B.

Hence, option B is the correct answer.

The underlined part is grammatically incorrect. When two dependent actions are mentioned, the first action is mentioned in simple present tense (v1), and the second action is in simple future tense (will/ shall + v1).
In the given sentence the second action is already in ‘simple future tense’ but the verb of the first action ‘blow’ should be replaced with ‘blows’ in order to make the sentence grammatically correct as the subject ‘the wind’ is singular.
Hence, option C is the correct answer.

The underlined part is grammatically incorrect. Since space inside the box is mentioned, ‘of’ preposition will be used, which is only mentioned in option B.

Hence, option B is the correct answer.

The underlined part is grammatically incorrect. ‘Brush past’ is a widely used phrase in English which means ‘to walk quickly past someone, usually because you do not want to speak to them’. The object of the sentence is usually placed after verb. Here ‘brushed past’ indicates the verb and ‘her’ is the object. Thus, the correct sequence is ‘brushed past her’ which is mentioned in option A.

Hence, option A is the correct answer.

 The question tag for a positive sentence is always negative. Thus, ‘does’ is the incorrect form and should be replaced with ‘doesn’t’ which is given in option A. Hence, option A is the correct answer.

 The use of “the most” shows that it is a superlative degree sentence. The use of ‘other’ in the underlined part is incorrect (as it is used in the case of comparison), the most relevant option to improve the sentence is option B, as ‘painter’ will be grammatically correct to represent a simple case of superlative degree of adjective. Hence, option B is the correct answer.

 The underlined part contains wrong use of tense, and should be improved by using the helping verb ‘are’ which is given in option B, Hence, option B is the correct answer.
