MAMMA MIA! has become a 22 entertainment phenomenon.
答案：(B) global
語意「MAMMA MIA已成為一個『全球性』的娛樂現象」，global（全球的）符合後文「全世界超過3000萬人愛上這部劇」；worthy（值得的）、sticky（黏的）、physical（身體的）都不合。
這一格四個形容詞語意差很遠，多數人都挑得掉。比較容易分心的是 worthy，因為「值得一看的娛樂現象」在中文裡聽起來也通順。
答案就在下一句：More than 30 million people all over the world have fallen in love with the characters, the story and the music.（全世界超過三千萬人愛上劇中的角色、劇情和音樂）。all over the world 正是 global 的換句話說。再往下 has been performed in more than nine languages（以九種以上的語言演出）也在支撐同一件事：這個現象是跨國的。克漏字常把形容詞的線索藏在下一句的具體數字裡，讀到 all over the world 就能定案。順帶注意 phenomenon 這個字，它是「現象」，前面用形容詞說明它的規模或性質，global entertainment phenomenon 就是「全球性的娛樂現象」。
worthy：值得的，常見的用法是 be worthy of something 或 a worthy cause（有意義的目標），直接拿來修飾 phenomenon 語意空泛，也對不上後文的數字。sticky：黏的，與語境無關。physical：身體的、實體的，這裡談的不是身體層面的現象。
a global phenomenon（全球性的現象）、all over the world（全世界）、fall in love with（愛上…）、be worthy of（值得…）、be performed in（以…演出）、more than（超過…）。
