答案：(B) eliminating
eliminate 是「根除、消滅」，用於疾病、貧窮、問題這類抽象事物，本句指蚊帳是遏止瘧疾擴散的最大希望；expanding（擴大）語意相反，deleting（刪除，用於文字資料）、assisting（協助）都不合。
答對率 32%。
eliminate 與 delete 的中文都能翻成「消除」，你大概把兩個字當同義字。使用對象完全不同：delete 用於文字、檔案、資料這類能按刪除鍵的東西（delete a file／a message）；eliminate 用於抽象事物——疾病、貧窮、危險、對手（eliminate poverty／malaria）。瘧疾的擴散不可能用 delete。
These nets are recognized… as the best hope for ___ the spread of malaria——既然是 the best hope（最大的希望），空格必然是正面的、對抗疾病的動作。expanding（擴大）剛好站錯邊。
eliminate 在競賽裡是「淘汰」，多用被動：Our team was eliminated in the first round.。
eliminate poverty／disease（根除貧窮／疾病）、be eliminated from a competition（在競賽中被淘汰）、delete a file（刪除檔案）、the spread of（…的擴散）。
