English

The correct verb form after 'let' is the base form without 'to'. Therefore, 'let me take time off work' is grammatically correct.

The correct word is 'Preserving' because it means protecting something from harm or destruction, which fits the context of preventing extinction of flora and fauna in rain forests.

A numismatist studies or collects coins, just as a philatelist studies or collects stamps. This analogy shows the relationship between a specialist and their subject of study or collection.

The analogy COOL : FROZEN shows a relationship of degree or intensity, where 'frozen' is a more intense state of 'cool.' Similarly, WARM : HOT follows the same pattern, with 'hot' being a more intense state of 'warm.' The other options do not show this degree/intensity relationship.

Sensitization leads to an allergic reaction, just as habituation leads to becoming inured (accustomed or desensitized) to a stimulus. Both pairs show a cause-effect or process-result relationship.

An agenda is a list or plan for a meeting, just as a programme is a plan or schedule for a function. Both pairs show a relationship where the first item is a plan or outline for the second event.

The phrase 'I promise to stand by you in all circumstances' is the correct idiomatic expression meaning to support someone consistently. 'Stand with' is less commonly used in this context and does not convey the same meaning as 'stand by.'

The analogy COMPLAIN : CARP is based on synonyms or near-synonyms, as 'carp' means to complain or find fault. Similarly, 'argue' and 'debate' are related as forms of discussion or disagreement, making option B the correct analogy. Option D (drink : guzzle) is also a synonym pair but does not match the style of the original pair as closely as B does.

The analogy compares 'RELEVANT' to 'CRUCIAL', where 'crucial' is a stronger, more important form of 'relevant'. Similarly, 'peripheral' means less important or marginal, and 'central' means most important or crucial, making option D the correct analogy.

The sentence is a third conditional, which refers to a hypothetical past situation and its possible past result. The correct form is 'would not have drowned' to indicate that if the help had been given, drowning would have been avoided.
