When people encounter a complex issue and form an opinion, how thoroughly have they 26 all the important factors involved before they make their decisions?
答案：(B) examined
語意「他們有多徹底地『檢視』過所有重要因素」，examined（檢視）符合這種審慎評估的語境；conveyed（傳達）、solved（解決）、implied（暗示）都不合。
examine 在你腦中大概綁在 exam（考試）上，第一個念頭是「考試、測驗」，於是覺得「考試所有重要因素」講不通，就把它放掉了。答對率只有 40%，這個字義落差是主因。examine 的核心意思其實是「仔細檢查、審視」，醫生 examine a patient（為病人做檢查）用的就是這個意思；「考試」那層意思反而是從「檢驗程度」引申出來的。
先看句子在問什麼。how thoroughly（多麼徹底地）這個副詞已經把答案框住了：能被 thoroughly 修飾的動詞，必須是可以「做得徹不徹底」的動作，也就是要花時間逐項檢視的動作。再看受詞：all the important factors involved（所有相關的重要因素）。跟 factors 搭配的動詞，慣用的是 examine、consider、weigh 這一類「檢視、考量、權衡」，而不是 solve。下一句直接把答案講出來：The answer is: not very thoroughly（答案是：並不怎麼徹底）。作者說的是人們沒有把因素看得夠仔細，指的正是「檢視」這個動作。整篇的主旨句也擺在第一行：Most human beings actually decide before they think.（大多數人其實是先做決定才思考）——沒有仔細檢視就下判斷，是本文從頭到尾在講的事。順帶注意 involved 的位置：the important factors involved 意思是「相關的重要因素」，involved 擺在名詞後面，等於 that are involved；擺在名詞前面的 involved parents 是「積極參與的父母」，意思不一樣。
conveyed（傳達）：convey an idea 是把想法傳給別人，句中沒有傳達的對象。solved（解決）：因素不是問題，不會被「解決」；能被 solve 的是 problem、puzzle、mystery。implied（暗示）：暗示是說話的人不把話講明，與考慮得周不周全無關。
take a close look at（仔細檢視…）、weigh the pros and cons（權衡利弊）、the factors involved（相關的因素）、convey a message（傳達訊息）、solve a problem（解決問題）、imply that（暗示…）。
Most human beings actually decide before they think. When people encounter a complex issue and form an opinion, how thoroughly have they 26 all the important factors involved before they make their decisions? The answer is: not very thoroughly, 27 they are executives, specialized experts, or ordinary people in the street. Very few people, no matter how intelligent or experienced, can 28 all the possibilities or outcomes of a policy or a course of action within just a short period of time.
Those who take pride in being decisive often try their best to consider all the factors beforehand. 29 , it is not unusual for them to come up with a decision before they have the time to do so. And 30 an opinion is formed, most of their thinking then is simply trying to find support for it.
