Prepositions

The correct preposition to use with 'pure milk' in this context is 'of', as in 'sweets made of pure milk.' This indicates the sweets are composed from pure milk. 'From' is less appropriate here because 'made from' is used when the original material changes its form, but 'made of' is preferred for ingredients that remain identifiable.

The correct preposition to indicate someone's presence at their residence is 'at'. Therefore, 'He is at home.' is the correct phrase. Other options do not fit the context appropriately.

The correct preposition to use with 'infested' when indicating the presence of insects is 'with'. The phrase 'infested with insects' is the standard and grammatically correct expression.

The correct preposition to use with a specific point in time like 'midnight' is 'since,' indicating the starting point of an action continuing to the present. 'In,' 'for,' and 'on' are incorrect in this context.

The correct preposition to use with 'suffered' in this context is 'from,' as in 'We suffered from your neglect.' This is the standard collocation in English.

The correct preposition to use with 'polite' when referring to people is 'to'. Therefore, 'Always try to be polite to others.' is correct.

The correct preposition to use when indicating blindness in relation to an eye is 'with.' The phrase 'blind with one eye' is the standard and idiomatic expression in English.

The correct preposition to use with 'road' in this context is 'on' because we say someone is walking on a surface such as a road.

The correct preposition to use with 'fond' is 'of'. The phrase 'fond of' means to like or enjoy something, so 'He is fond of mangoes' is correct.

The correct preposition to use with 'good' when referring to a subject or skill is 'at'. Therefore, 'Samra is good at mathematics' is the correct sentence.

The correct preposition to use in this context is 'after' because it indicates pursuing or chasing someone, which fits the sentence meaning. 'On' does not correctly express this action.

The verb 'await' is a transitive verb that takes a direct object without a preposition. Therefore, the correct phrase is 'She is awaiting the result.' The article 'the' is necessary before 'result' because it refers to a specific known outcome. Using a preposition such as 'on' before 'result' is incorrect in this context. Hence, the blank should be filled with the article 'the' (option C).

The correct preposition to complete the phrase 'I have claim ___ you' is 'over,' as in 'I have a claim over you,' meaning a right or entitlement concerning you. 'On' is not typically used in this context.

The correct preposition to complete the sentence 'Take the book _____ the table.' is 'off' because it indicates removing the book from the surface of the table. 'In', 'Into', and 'Out of' do not fit the context of removing something from the top of a surface.

The phrase 'profit from' is the most commonly used and grammatically correct preposition to indicate benefiting or gaining advantage from something, such as a lecture. While 'profit by' can be used to describe the means or method by which profit is achieved (e.g., 'profit by cutting costs'), it is not typically used to express benefiting from an event or source. Therefore, the correct preposition in the sentence 'I'm sure to profit ___ his lecture' is 'from'.

The correct preposition to use when indicating cause of death is 'of'. The phrase 'He died of fever' is grammatically correct and commonly used in English.
