English Grammar and Usage

The word "yesterday" indicates past time, and since Suresh was in the middle of running when he fell, the past continuous tense "was running" is correct. "Is running" is present tense, "has been running" connects past to present, and "has run" is present perfect - none of which fit the past context with an interrupted action.

The clause "Raju (describe) the football match" is a relative clause modifying "the way". Since the main verb "was" is in past tense, the describing action also happened in the past, so "described" (simple past) is correct. "Describe" would be present tense, "describing" would create a continuous form that doesn't fit the sentence structure, and "description" is a noun.

The sentence describes a completed request without specific time context. The simple past tense "asked" is appropriate here as it states what the minister did. "Asking" is a gerund, "was asking" would mean the minister was in the middle of asking, and "is asking" is present tense. The simple past "asked" is the most natural choice for reporting a minister's action.

Case of past perfect continuous tense. When we refer to an action that 'had already been' going on at the occurence of the other action, we use past perfect continuous tense. (Had + been + verb+ing)

The subjective case of the pronoun is to be used here. Hence, option 1.

Whom is the objective case pronoun used as the object of a verb or preposition. In 'Whom do you wish to see?', 'whom' functions as the object of the verb 'see' - you are seeing someone. Who would be incorrect here because who is nominative (subject case), not objective.

Whom is the objective case pronoun. In 'Whom do you wish to visit today?', whom serves as the object of the verb 'visit' - someone is being visited. Who is incorrect because it's the nominative (subject) form, but the person is receiving the action of visiting, not performing it.

Who is the correct choice because it functions as the subject of the embedded clause 'who is best qualified.' The full structure is 'You do believe [who] is best qualified' - in this clause, who is the subject of the verb 'is.' Many people mistakenly use whom in such constructions, but the pronoun case is determined by its role within its own clause, not the main sentence.

The blank is the object of 'have chosen' in the relative clause. You choose someone (whom), and the entire clause 'Whom you have chosen for this task' functions as the subject of the sentence.

The blank is the object of the verb 'hold' in the structure 'hold [someone] responsible'. Whom is used as the object of a verb or preposition.

The blank is the subject of the verb 'robbed'. The phrase 'I believe' is a parenthetical clause that can be removed to see the structure more clearly: 'He is the man ________ robbed the first national bank.'

This is a cleft sentence structure 'Was it _______'. In formal grammar, the subject complement after 'was' uses the subject case: 'It was he'. The same applies in the question form.

Similar to the previous question, this uses a cleft structure 'It was _______'. In formal grammar, the subject complement uses the subject case: 'It was she' who was being thought about.

This is an elliptical comparison: 'Are the Russians freer... than we [are]?' The understood verb 'are' requires the subject case 'we' as the subject of that verb.
