Idioms and Phrases

(1) Because I developed high fever overnight . Since a reason is stated in the first part so correct conjunction “because” should be stated and pronoun I makes it clear about whom we are talking about.

(1) His thirst being satisfied. Past Indefinite tense is used in the sentence.

The idiom 'a close shave' means a narrow escape from danger or a difficult situation, barely avoiding something bad. It originates from shaving - if you have a 'close shave,' you narrowly miss cutting yourself. 'Shaving daily' and 'not hygienic' are literal interpretations, while 'real encounter' doesn't capture the idiom's meaning of escaping harm.

The idiom 'egg on' means to urge, encourage, or prompt someone to do something, often something foolish or risky. It doesn't relate to eggs literally - it comes from 'edge on' meaning to push or spur. 'Shrewd' (clever), 'renounce' (give up), and 'trivial' (unimportant) don't capture the meaning of encouraging or instigating action.

The idiom 'eat one's heart out' means to suffer in silence, often from envy, longing, or unfulfilled desire. It doesn't mean being hungry ('voraciously hungry'), taking action ('decisive step'), or providing insight. The expression comes from the idea of consuming oneself with emotion. Note: the question uses 'one`s' with a backtick instead of a proper apostrophe, but this is a minor typographical issue that doesn't affect comprehension.

The idiom 'end in smoke' means to come to nothing, produce no results, or end in failure - like smoke that vanishes without a trace. It doesn't mean victory ('finished victorious'), hostility ('openly hostile'), or getting rid of something ('dispense with'). The imagery is of something insubstantial and disappearing.

The idiom 'fly in the face of' means to openly defy, contradict, or go against conventions, authority, or accepted wisdom. It doesn't mean embarrassment ('feel embarrassed'), influence ('influence somebody'), or progress ('make progress'). The imagery suggests something flying directly into or against something else, openly opposing it.

The idiom 'show the white feather' originates from the belief that a white feather in a gamecock's tail indicated cowardice. Thus, it means to display fear or act cowardly, particularly when facing danger or difficulty.

'Go haywire' refers to wire used in hay baling that sometimes tangled or snapped. When something goes haywire, it becomes chaotic, disorganized, or stops functioning properly. Option A correctly captures this meaning of becoming disordered.

'Fish in troubled waters' means to exploit a confusing or difficult situation for personal gain. Just as fish might be easier to catch in disturbed waters, some people take advantage of chaotic circumstances. Option B correctly identifies this exploitative meaning.

'Cut no ice' means to be ineffective or fail to impress someone. Option D correctly states it means having no effect or influence. The idiom likely comes from ice cutting not working when conditions aren't right, signifying futile effort.

'Make a clean breast of' means to fully confess or reveal something, often a wrongdoing or secret. Option C is correct: the phrase suggests baring oneself completely, holding nothing back, similar to revealing a clean breast without concealment.

'Make head or tail of something' means to understand or comprehend it. Option A is correct. The idiom suggests that if you can't distinguish the top (head) from the bottom (tail) of something, you can't make sense of it at all.
