English Grammar and Usage

Angle for means to try to get something indirectly. 

General truths and habitual actions use the simple present tense. The sun rising in the east is a universal fact, so "rises" is correct.

Present continuous tense is used to express the idea that something is happening now, at this very moment.

Without specific time markers, the simple present "washes" indicates a habitual action - something he does regularly. This is the most neutral choice.

Has just finished uses present perfect tense with "just" to show an action completed very recently with connection to the present. This fits the context perfectly.

Case of present perfect contnuous tense.  'For the last two hours' suggests part completion and part continuation.

For repeated actions in the past that have relevance to the present, we use present perfect tense with 'has been'. 'He' is third-person singular, so 'has' is correct, not 'is', 'am', or 'will be'. The phrase 'many times' indicates repeated action, making present perfect the appropriate tense.

The sequence of events requires past perfect tense for the earlier action. 'Had left' shows the train's departure occurred before 'I reached' (simple past). This is a classic case of past perfect for the earlier of two past actions. 'Is leaving' is present continuous, 'has been leaving' is present perfect continuous, and 'has left' is present perfect - all incorrect for this sequence.

The time marker 'last September' indicates a specific completed past action, requiring simple past tense 'left'. 'Leaving' is not a complete verb form, 'had left' is past perfect (used for earlier of two past actions), and 'has left' is present perfect (for past actions with present relevance). Simple past is correct here.

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.
