...is active in assisting consumers involved in 13 with businesses or manufacturers.
答案：(D) disputes
disputes with businesses or manufacturers（與企業或製造商的糾紛）表示委員會積極協助與廠商發生消費糾紛的消費者；references／shortages／purchases 均不符合此處語意。
dispute 你大概只記得動詞的「爭論、提出異議」，沒認出它當名詞時是「糾紛、爭議」，而且是消費新聞裡的高頻字——消費糾紛就是 consumer disputes。答對率四成八，多半是這個名詞用法太陌生。
四個選項都是名詞複數，文法上都填得進 involved in ___ with businesses，可見這一格考的是語意。有兩個線索要一起看：一是同句前半的 assisting consumers（協助消費者）——既然需要協助，表示有麻煩要處理；二是 with businesses or manufacturers（與企業或製造商之間的），表示這件事發生在雙方之間。既要有麻煩、又要是雙方之間的，只有糾紛說得通。be involved in a dispute with sb 是很常見的組合。
purchases（購買）最誘人，因為消費者本來就在購買，involved in purchases 文法上也通；但「協助消費者處理與企業之間的購買」語意空洞，接不上 assisting 所暗示的有問題要解決。references（參考資料、推薦函）與 shortages（短缺）都不是消費者與企業之間的關係，套進 with businesses 這個結構就讀不通。鑑別度 60，分開的是有沒有把 assisting 這個字讀進來——它是整句最關鍵的提示，卻很容易被當成無關緊要的背景。
a dispute with sb（與某人的糾紛）、be involved in（涉入、牽涉其中）、settle a dispute（解決糾紛）、raise consumer awareness（提高消費意識）、manufacturer（製造商）、well-being（福祉）
