Newspapers, radio and TV stations, and websites have participated in the April 1 tradition of making 20 reports in order to fool their audiences.
答案：(A) fictional
語意「製作『虛構的』報導來愚弄觀眾」，fictional（虛構的）符合愚人節惡作劇的語境；essential（必要的）、ancient（古老的）、subjective（主觀的）都不合。
fiction 你記得是「小說」，所以 fictional 容易被讀成「小說的」，一配上 reports（報導）就覺得搭不起來。其實 fiction 的核心意思是「虛構的內容」，小說只是其中一種形式；fictional reports 就是「虛構的、捏造的報導」。
同一句句尾已經把答案講白了：in order to fool their audiences（為了愚弄觀眾）。要騙人，報導當然是假的。下一句的例子也在示範同一件事：The BBC once reported that Swiss farmers were experiencing a spaghetti crop（BBC 曾報導瑞士農民迎來義大利麵大豐收），還播出人們從樹上採收麵條的畫面。
essential（必要的）、ancient（古老的）、subjective（主觀的）都不是「假的」。其中 subjective 最需要留意：一篇主觀的報導講的可能仍是真事，只是帶了個人觀點，和「刻意捏造」是兩回事，這個差別正是這一格的關鍵。
fictional（虛構的）、fictitious（捏造的、假的，語氣更強調刻意造假）、fiction（虛構作品；虛構的事）、non-fiction（非虛構作品）、fool sb into Ving（騙某人去做……）、in order to V（為了……）、play a trick on sb（捉弄某人）、hoax（惡作劇、騙局）、make up a story（編造故事）。
