Sentence Completion

'The state of affairs' is a singular noun phrase requiring a singular verb. 'Is' correctly agrees with this singular subject. 'Are' and 'were' are plural verbs, while 'has' is grammatically incorrect in this context as a main verb.

'Slow and steady' is a singular collective phrase (one approach or strategy), so it requires the singular verb 'wins'. This refers to the proverb 'Slow and steady wins the race.' Plural verbs like 'win' would be grammatically incorrect.

A carpenter and a goldsmith are two different persns . zhence, it will take plural verb

Since subject is singular i.e. "intrduction". Hence, it will take singular verb

'Ago' is used to indicate time elapsed before the present moment ('I saw him two months ago'). 'Before' typically requires a reference point or event ('two years before that'), 'since' implies from a past time until now, and 'for' indicates duration. With simple past tense and a time reference from now, 'ago' is correct.

The structure 'adjective + enough + to-infinitive' expresses sufficient degree ('foolish enough to listen'). 'Too' would mean excessive ('too foolish to listen' would mean he was so foolish that he would not listen). 'Also' and 'as well' are not grammatically correct in this construction.

'Though' introduces a concessive clause meaning 'despite the fact that' (Clever though he was = Although he was clever). This construction emphasizes the contrast between cleverness and inability to solve. 'As' creates a different meaning (reason), 'as though' means 'as if', and 'even though' requires the subject after it ('even though he was clever').

"Unless" is appropriate

The sentence uses 'hardly...when' to show one action immediately followed another. The first action (finishing lunch) occurred before the past moment of knocking, so past perfect 'had' is required. 'Was' is simple past and incorrect for this sequence. 'Did' and 'would' do not fit the grammatical structure.

 I wish you would keep to the subject instead of digressing like this.

'For' is used with a duration of time ('for three years'). 'Since' requires a specific starting point (since 2020), not a duration. 'From' and 'before' are not correct for showing how long an action has continued up to the present with present perfect continuous.

'Though' introduces a concessive clause showing contrast (Despite being clever, he could not solve). This is the standard way to express unexpected opposition. 'As' would imply causation, 'Even' is incomplete, and 'In spite of' requires a noun phrase following it, not a clause.

The 'such...that' correlative conjunction connects the degree of quality (such beauty) with its consequence (princes came to woo her). 'As' creates different constructions, 'for' is a conjunction meaning 'because', and 'so' requires 'that' in the correlative 'so...that', not 'such'.

 "Strong though" or "though strong" means same 

'Would rather' is always followed by 'than' in comparative structures (would rather be X than Y). This expresses preference between two options. 'To' is incorrect, 'but' changes the meaning to contrast, and 'none of these' doesn't fit the grammatical structure.

 "so as to" is the correct usage.

In time clauses introduced by 'when', we use the present simple tense to refer to future time, not the future tense. This is a standard grammar rule in English. 'Will arrived' is grammatically incorrect (double future markers), while 'will be arriving' and 'will have arrived' are future forms that don't belong in time clauses.

Past perfect continuous tense will be used. We use the Past Perfect Continuous to show that something started in the past and continued up until another time in the past.

The subject "father" is singular. Hence, we will use singular verb

 This is the case of present perfect tense

Die is correct, because the sentence is in the present tense.

 This is the case of present perfect tense. In the above sentence 'who' relates to the 'players'. So, 'have been' will be used. 

The perfect participle 'having applied' is used here to show that one action (not applying in time) happened before another (could not get scholarship). The structure 'Not having done X, subject could not Y' is the correct construction. 'Being applied' is passive voice with wrong tense, 'applied' lacks the perfect aspect needed, and 'applying' doesn't convey the completed action.

Option (3) is correct.

After prepositions like 'of', we use gerund forms. Since the torture happened before the complaint, we need the perfect gerund 'having been tortured'. The passive voice is essential because he was the recipient of the action, not the doer. 'Tortured' is a past participle, 'torturing' is active voice, and 'having tortured' is active perfect gerund.
