題目

According to the passage, which of the following hypotheses is made by scientists from Cornell University? A. The mediocrity principle rules out the possibility of life forms on other planets. B. Aliens from Earth-like planets might use light waves to communicate. C. Extraterrestrials from 8,500 planets might have translated signals from Earth. D. Aliens might need to interpret about 3,000 languages to understand Earth.

官方答案

• 答案：D. Aliens might need to interpret about 3,000 languages to understand Earth.

解析

文中明確記載所羅門尼德斯的主張：外星人須把光波解讀成聲音、分析約三千種人類語言，才能看懂地球訊息，故 D 正確。A 錯，mediocrity principle 是說既然地球有生命，類地行星通常也可能有生命，並未排除其他星球的生命；B 錯，文中說外星人要把「光波」還原成聲音才能理解，並非以光波溝通；C 錯，8,500 是地球訊號已到達的恆星數量，不是已翻譯訊號的外星行星數。
