It 20 stress and creates calmness and confidence.
答案：(C) reduces
語意「它『減少』壓力，創造平靜與自信」，reduces（減少）符合正面效果的描述；imposes（施加，語意相反）、offends（冒犯）、disturbs（干擾，語意相反）都不合。
這一格多數人能對，但有一個陷阱值得提醒：impose 很常跟 stress、pressure 一起出現（impose pressure on sb，對某人施壓），所以背過 impose 的人反而可能因為「看到熟悉的搭配」被拉走。背搭配不能只背「哪兩個字常一起出現」，還要記住方向。
靠 and 後面那半句定方向，這是很好用的一招。整句是 It {20} stress and creates calmness and confidence.，and 連接兩個並列的動作，方向必須一致。後半的 creates calmness and confidence（帶來平靜與自信）明顯是正面的，所以前半對 stress 做的事也必須是正面的 —— 對壓力做正面的事，只能是「減少」。連接詞兩邊同向，一邊讀不懂就看另一邊，這個技巧在克漏字非常好用。再往下一句確認：Relaxation and a feeling of joy are among the first noticeable differences（放鬆與愉悅感是最早能察覺到的改變），整段都在鋪陳正面效果。
imposes（強加、施加）方向是「加上去」，例 impose a tax on imports（對進口品課稅）、impose one's views on others（把自己的看法強加於人），與後半的 creates calmness 語意矛盾。offends（冒犯）受詞要是人，例 offend the audience（冒犯觀眾）。disturbs（打擾、擾亂）方向也是負面，例 disturb the peace（擾亂安寧）。三個誘答選項有兩個是負面動詞，把 and 兩邊的方向對齊，就能一次刷掉。
reduce stress（減輕壓力）、relieve stress（紓解壓力）、under stress（在壓力之下）、impose A on B（把 A 強加於 B）、build confidence（建立自信）、be among the first to V（是最早……的其中之一）、noticeable（明顯的、看得出來的）。
