For the question seeking a synonym of Bolster, the correct answer is B: Support. The word bolster means to support or strengthen, or to improve something, often by providing encouragement or material aid. It implies an action that provides reinforcement, making something more firm, resilient, or effective. Support directly aligns with this meaning, referring to holding up, reinforcing, or providing assistance to something or someone. Both terms are commonly used to describe actions that add strength, stability, or confidence to a person, idea, or structure. Recognizing this function of reinforcement is key to identifying 'support' as the most appropriate synonym for 'bolster'.
Let's consider why the other options are incorrect. Option A: Weaken means to make or become weak. This is the direct opposite of bolstering, which aims to strengthen. Thus, 'weaken' is an antonym. Option C: Destroy means to put an end to the existence of (something) by damaging or attacking it. This action is antithetical to bolstering, which aims to preserve and strengthen rather than annihilate. Lastly, option D: Break means to separate into pieces as a result of a blow, shock, or strain, or to render something inoperative. Similar to 'destroy' and 'weaken', 'break' implies damage or failure, which is the inverse of the strengthening action of bolstering. Therefore, 'support' is the only option that accurately conveys the sense of reinforcing or strengthening implied by 'bolster'.
