Noisy British fans, after setting off some rockets and fireworks to cheer for 18 team, broke through a thin wire fence and started to attack the Italian fans.
答案：(D) their
their team（他們的隊伍）所有格代名詞，指英國球迷為「自己的」球隊加油，符合語意邏輯。a（不定冠詞，語意應為特定的「自己的」球隊而非任一隊伍）、that（那個，缺乏明確指涉）、each（每一個，語意不合，此處指單一特定隊伍）都不符合。
空格後面是一個單數名詞 team，你會覺得 a 與 each 都放得進去，就憑語感挑一個。
這是指標勾環：空格要的是一個回指前面那群人的所有格。先讀完整句——Noisy British fans, after setting off some rockets and fireworks to cheer for ______ team（吵鬧的英國球迷施放煙火為______球隊加油）。為球隊加油的是英國球迷，他們要加油的當然是自己支持的那一隊，所以空格要的是所有格 their，回頭指向句首的 Noisy British fans。填進去讀成 cheer for their team（為自己的球隊加油）。cheer for 後面要說清楚是為誰加油，而這個「誰」一定要在前後文找得到根據，不能憑空給一個沒有指涉的名詞。
a team 是「某一支球隊」，隨便哪一隊都可以，與「為自己這一隊加油」的情境對不上；each 後面雖然接單數名詞，但 each team 是「每一支球隊」，英國球迷不會為兩隊都加油；that 當限定詞時要指一個前面明確提過的單一事物，這裡前面提到的是兩支球隊，指不清楚是哪一支。
cheer for（為……加油）、set off（施放、引爆）、break through（衝破、突破）、a wire fence（鐵絲網）、each ＋ 單數名詞（每一個）、their（他們的，所有格限定詞）。
