It was carried on sailing ships around the world because it was found to help prevent scurvy, a disease that often 25 sailors on long voyages.
答案：(A) bothered
bother 在此是「困擾、折磨」，主詞是疾病：壞血病常折磨長途航行的水手；suffer 的主詞必須是受苦的人（sailors suffered from scurvy），主客顛倒，contacted（聯絡）、wounded（使受外傷）也都不合。
bother 你記得的大概是「打擾」，而且主詞一定是人（Don't bother me. 別煩我／Sorry to bother you. 抱歉打擾了）。這裡的主詞卻是一種疾病，意思也轉為「困擾、折磨」——疾病、疼痛、傷勢都可以當 bother 的主詞：My back has been bothering me lately.（我的背最近一直在困擾我）。
四個選項均為及物動詞的過去式，填入關係子句後文法上都能成立，因此判斷的依據在主詞與受詞的方向。空格所在的關係子句以 a disease 為先行詞，主詞是疾病、受詞是 sailors，需要一個能表示「疾病使水手受苦」的動詞；bother 用於疾病、疼痛、傷勢時即「使不適、折磨」，方向相符。作答線索在同一句前半 because it was found to help prevent scurvy（因為人們發現鳳梨有助於預防壞血病），空格所在的同位語進一步說明壞血病對水手造成的影響。凡是四個選項均為及物動詞、文法上都填得下的題目，判斷步驟相同：先確認主詞與受詞各是動作的發出者或承受者，再檢查各選項要求的方向是否與句子一致。
suffered 的方向與本句相反：suffer 的主詞須是承受痛苦的一方，表示罹患疾病時後接 from，如 Sailors often suffered from scurvy.（水手常罹患壞血病）；本句主詞是疾病，不能作 suffer 的主詞。contacted 是「聯絡」，主詞須是人；表示「染上疾病」的動詞是 contract，與 contact 形近義異，宜一併分辨。wounded 指刀槍或外力造成的外傷，不用於疾病。
bother sb（困擾某人）、be bothered by（受…困擾）、suffer from a disease（罹患疾病）、contract a disease（染病）、prevent scurvy（預防壞血病）、on long voyages（在長途航行中）。
