The Louvre's Tactile Gallery, targeted at the blind and visually 17 , is the only space in the museum where visitors can touch the sculptures, with no guards or alarms to stop them.
答案：(C) impaired
過去分詞 impaired 作形容詞，visually impaired（視覺受損的）是描述視障人士的常見固定用語，與 the blind 對等並列，共同修飾這個藝廊的服務對象。impair（原形動詞）、impairs（限定動詞）、impairing（現在分詞，主動語意不合，視障是被動狀態）皆不合。
四個選項是同一個字 impair 的四種形態，你會直覺開始分主動被動、找意義主詞。
先看它跟誰並列：targeted at the blind and visually ______，and 連的是 the blind（視障者）與空格這一串，兩邊都是這個展廳服務的人。空格前的 visually 是副詞，副詞修飾的是形容詞或分詞，所以空格填的是被它修飾的那個字。再判方向：視覺是「受到損害」的一方，不是自己去損害別人，所以用過去分詞 impaired。visually impaired 是講視障最常見的說法，整組記起來就好。填進去讀成 the blind and visually impaired（視障與視覺受損的人）。鑑別度只有 35，但它本身不難：副詞後面接分詞、加上「受損」要用被動這兩層，各種程度的人都答得出來，題目自然分不出高低。
impair 與 impairs 都是限定動詞，前面沒有主詞可以搭；impairing 是現在分詞、表示主動去損害別人，方向相反。
visually impaired（視覺受損的、視障的）、hearing impaired（聽覺受損的）、impair（損害、削弱）、be targeted at（針對……而設）、the ＋ 形容詞（表一群人，the blind 視障者）、sculpture（雕塑作品）。
