English Grammar: Sentence Completion

The verb 'advanced' means 'moved to an earlier time.' When indicating time changes, 'by' shows the amount of shift. 'On' is used for specific dates, 'of' shows possession or belonging. The sentence means the visit was moved earlier by a duration of three months, so 'by' is correct.

'Beside' means 'at the side of' or 'next to,' which perfectly describes the murderer's position relative to the dead body. 'Front' would require 'in front of,' and 'behind' would mean the murderer was positioned behind the body. 'Beside' is the standard preposition for adjacent positioning.

I hear that... is a fifurative expression. When you say 'I hear that 'you imply that it's common knowledge.

But is used to stress contradiction between the halves of the statement.

An is used before word beginning with a vowel/vowel sound.

The subject 'the parrot' is singular, so 'sit' is grammatically incorrect. 'Was sat' is non-standard English, and while 'is standing' is grammatically possible, 'will be sitting' is the most natural and grammatically correct option among the choices.

Otherwise is used to connect two clauses where the second clause shows the bad thing that would happen if the first clause doesn't happen.

The sentence requires the present perfect tense 'has given' to indicate an action completed in the past with relevance to the present. 'Give' is present tense, 'gave' is simple past, and 'giving' is a participle that doesn't fit grammatically.

The correct preposition after 'congratulated' is 'on'. We congratulate someone ON their achievement or success. 'Of' and 'for' don't fit with this verb in this context.

The word 'lest' introduces a clause showing purpose or fear of something happening, and it requires the subjunctive mood - the base form of the verb. 'Fall' is the correct base form, while the other options are tensed forms that don't work with 'lest'.

'Since' here means 'because' or 'given that'. The structure 'Since you say so, I must believe it' is a logical deduction meaning 'because you claim it is true, I'm compelled to accept it'. 'From' and 'For' don't establish this causal relationship.

This is a first conditional structure: If + present simple, will + base verb. 'If you go' (present) leads to 'you will see' (future result). Option A is present tense, C is present perfect, and D is past perfect - none fit the conditional pattern.

'No doubt that' is the correct construction when stating a fact with certainty. The word 'that' introduces the clause following 'doubt'. 'If' would suggest uncertainty, 'because' changes the meaning, and 'those' is grammatically incorrect.

The verb 'overflow' is irregular like 'flow' - its past participle is 'overflown'. Present perfect 'has overflown' is correct. 'Overflow' is base form, 'been overflowing' is continuous, neither fits grammatically.

'Books' are countable nouns, so they require 'many' not 'much'. 'Much' and 'so much' are used with uncountable nouns like water, time, or information. 'Many' is the correct quantifier for countable items.

The phrasal verb 'broke into' means to enter forcibly or illegally. 'Broke in' means to interrupt, 'broke at' and 'broke on' are not standard phrasal verbs in this context of entering a building.

'Had learnt' is past perfect tense, showing an action completed before another past time. 'Has learnt' is present perfect (wrong), 'will learnt' is grammatically incorrect (should be 'will learn'), and 'is learning' is present continuous. Past perfect fits with a past narrative.

The past perfect tense 'had left' is correct because her leaving happened BEFORE she came. Past perfect shows the earlier of two past actions. 'Left' is simple past, 'has left' is present perfect (wrong timeframe), and 'leave' is base form.

The subject 'ships' is plural, requiring a plural verb. Since the action happened 'six month back' (past time), we need the past tense 'were stolen'. Option A correctly uses the plural past tense to match the subject and time reference.

The sentence refers to a specific past year (1961), which requires the simple past tense 'passed'. Present perfect 'has passed' would be used for unspecified time, and past perfect 'had passed' would need another past event reference. 'Will pass' is future tense.

This is reported speech where Ramanujan's original statement would have used 'will'. In reported speech, 'will' changes to 'would' to backshift the tense. The original direct speech would be 'I will return next day'.

The phrase 'as you please' is a fixed idiomatic expression meaning 'in whatever way you want' or 'however you wish'. It gives complete freedom to the listener to choose their action or approach.

When referring to a specific person holding a particular title or position in an organization, we use the definite article 'the'. 'Shri Devi' appears to be a specific designation or title held by Kumari Sunena in the office.

The sentence describes a completed past action with a specific duration. Simple past 'spent' is appropriate here as it refers to a finished event. 'Spend' would be present tense, and 'are spending' is present continuous, neither of which fits a completed past event.
