It conveys the sense that “if it had not snowed, the plane could have taken off”. Hence, (2) is the correct answer.

The given sentence is a mixture of complex and compound sentence, it must have the same tense at all the places of the transitive verbs and “milked” is one of them. Hence, (1) is the correct answer.

As per the system of sequence of tenses, the past tense must be followed by the past tense and since there is reference “to the van” only “drone” can be used. Hence, (2) is the correct answer.

It is a proverb and a proverb usually has a fixed set of words. In the given sentence, “flock” is the most appropriate word for the said proverb. Hence, (2) is the correct answer.

It is a triple preposition and it means “from the side of”.

“Among” is used for more than two persons/places/things . 'Amidst' meaning in the middle of is incorrect.  Hence, (2) is the correct answer.

It is a regular action. So, (4) is the correct option.

'Are you' is the correct option here. Were/are is used with you. Since the sentence is negative, the question tag should be positive.

Watch out means ‘be attentive or careful’.

We should use ‘in’ for lab here as it refers to a room or enclosed space.

'Isn’t it' is the correct option here. Also, as the sentence is positive, question tag should be negative.

'Many' is the correct word as 'ways' is countable and use of ‘few’ would not make sense here as the sentence implies a positive meaning and ‘few’ does not fit with it.

'Might buy' shows probable future action. 'Buys' cannot be used as it is not a regular action.
