English Grammar and Usage

The narrative describes a background continuous action in the past, requiring past continuous tense 'was hunting'. This sets the scene for the main event 'there was a storm'. 'Is hunting' is present continuous, 'has been hunting' is present perfect continuous, and 'has hunted' is present perfect - all incorrect for this past narrative context.

The sentence structure 'It was clear that' indicates we need a past tense form. 'Had worked' (past perfect) shows he worked very hard before that past moment of observation. The other options are all present tense forms: 'have worked', 'are working', 'am working' - none fit with the past observation context established by 'was clear'.

The phrase 'ever since his boyhood' indicates an action starting in the past and continuing to the present, requiring present perfect continuous 'has been reading'. This tense emphasizes the ongoing duration from past to present. 'Reads' is simple present habit, 'is reading' is present continuous for now, and 'has read' is present perfect without the continuous aspect.

The adverb 'usually' indicates a regular habit, so we use simple present tense 'sleeps' with third-person singular subject 'child'. 'Sleeping' is not a complete verb form, 'has been sleeping' is present perfect continuous for temporary situations, and 'slept' is simple past. Simple present correctly expresses this habitual action.

The context suggests a current ongoing action, and option A 'is now trying' in present continuous tense best fits this. While the sentence alone is ambiguous without more context, 'is now trying' indicates an active current effort. 'Tried' is simple past, 'was trying' is past continuous, and 'has now been trying' would suggest longer duration. Present continuous is most likely.

The first clause needs simple present 'answers' for a habitual action, and the result clause needs 'won't write' for a future decision based on that habit. This creates a logical cause-effect relationship. Other options either don't show the habitual nature or use incorrect tenses for the future consequence.

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.
