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。
答對率 28%。
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）。
很多人選 suffered，因為「水手受苦」的畫面很直覺——但方向剛好顛倒。suffer 的主詞必須是「受苦的那一方」，而且表示罹患疾病時要用 suffer from：Sailors often suffered from scurvy.（水手常罹患壞血病）。本句的主詞是 a disease（疾病），疾病不會「受苦」，所以 suffer 放不進來。判斷這類題目，先問「主詞是施加的一方還是承受的一方」。
contacted 是「聯絡」，疾病不會聯絡水手（若要說「染上疾病」是 contract a disease，注意是 contract 不是 contact，這兩個字也常被混淆）；wounded 是「使受傷」，專指刀槍、外力造成的外傷，疾病不用這個字。
前半句 it was found to help prevent scurvy（鳳梨被發現有助於預防壞血病）已經說明壞血病是水手的大敵，空格所在的關係子句只是進一步描述這種病「常折磨」長途航行的水手。
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）。
