For instance, people who have a 23 sense of self-esteem usually act with confidence. 24 they have self-assurance, they do not need constant praise and encouragement from others to feel 25 about themselves.
答案：(A) positive
「正向的自尊」才會有自信，positive（正向的）呼應後面 act with confidence 的因果邏輯。common／normal（一般的/普通的）因果連結不夠緊密，weak（微弱的）則與「有自信」矛盾。

四個選項都是形容詞，而 common 與 normal 讀起來都很安全，如果沒把後半句一起讀，會覺得都說得通。
四個選項都是形容詞，可見這一格考的是語意，那就往後讀。整句是 people who have a ___ sense of self-esteem usually act with confidence（擁有……自尊感的人，通常表現得很有自信）。後半句給的是 act with confidence（表現得有自信），而能導出自信的自尊當然是正向的，填 positive。再往後讀一句更確定：Because they have self-assurance, they do not need constant praise and encouragement from others.（因為他們有自信，所以不需要別人不斷的讚美與鼓勵。）整段都在描述一個心理健康的人，方向一致。順便記一下 self-esteem 的常見搭配：high self-esteem（高自尊）、low self-esteem（低自尊）、positive self-esteem（正向的自尊）。
weak（微弱的）：方向相反，自尊薄弱的人不會表現得有自信。common（常見的）、normal（正常的）：兩個意思相近，依「同義的選項不可能只有一個對」可以一起砍掉；而且「常見的自尊」與「表現得有自信」之間沒有必然的因果。
