In the following sentence, out of the given alternatives choose the one which…

Answer: cool — meaning very cold, distant, or unfriendly.

Explanation: In the sentence "Relations between the two states have become glacial," the word 'glacial' is used metaphorically to describe relations that are icy or emotionally distant. Therefore, the choice that best matches this meaning is the one that conveys distance or lack of warmth.

• cool — Correct. Here 'cool' means distant or unfriendly, which matches the metaphorical sense of 'glacial' when applied to relationships.

• friendly — Incorrect. This is the opposite of the idea conveyed by 'glacial.'

• confused — Incorrect. 'Glacial' does not refer to confusion; it refers to a cold or distant quality.

• warm — Incorrect. 'Glacial' implies lack of warmth, so 'warm' contradicts the intended meaning.

Tip: Some words like 'glacial' can mean either physically very cold or metaphorically very slow or emotionally distant; use the sentence context (here, describing relations) to choose the correct sense.
