English

The correct idiomatic phrase is "Better late than never," meaning it is better to do something late than not at all. Option A "Late" completes the phrase correctly.

The correct preposition to use with 'ignorant' when indicating what someone lacks knowledge about is 'of'. The phrase should be 'He is ignorant of what he pretends to know.' However, since 'of' is not provided as an option, none of the given options (to, with, on, from) are correct. The question is flawed because the correct preposition 'of' is missing. The best correction would be to replace option A with 'of' and mark it as the correct answer.

The correct preposition to use with 'feel' in this context is 'about,' making the phrase 'How do you feel about their coming.' This is a common English expression to ask someone's opinion or feelings regarding an event or action.

The word 'portent' means a sign or warning that something, especially something momentous or calamitous, is likely to happen. 'Omen' is a synonym that also means a sign or warning of a future event, making it the correct answer.

Excessive admiration or praise is best described by the word 'Adulation,' which means high praise or flattery beyond what is normal or sincere.

The word 'caress' means to touch or stroke gently and affectionately. Among the options, 'fondle' is the closest synonym, as it also means to touch gently, often with affection. 'Adore' and 'kiss' are related but not direct synonyms, and 'hate' is an antonym.

The correct preposition to complete the sentence 'Someone was having a party in the flat ______.' is not 'Under', 'Below', or 'Into'. None of these options fit naturally. The sentence typically requires a preposition like 'above', 'next door', or 'upstairs'. Therefore, 'None of the above' is the best choice among the given options.

Influenza is caused by a virus, so the analogy asks for the causative agent of typhoid, which is caused by bacteria. Therefore, the correct answer is 'Bacteria'.

The correct phrase is 'should unitedly undertake' because 'undertake' is the base verb form required after 'should,' and 'unitedly' correctly modifies the verb to indicate joint action. Option C is incorrect because 'undertaken' is the past participle, which does not fit here.

The correct spelling of the word referring to a military unit is 'Battalion', which matches option B. The other options are misspellings.
