The author's hypothesis concerning the cold prehistory of life would be most
weakened if which of the following were true?
A. Cosmic rays are unlikely to trigger the formation of simple molecules.
B. Tunneling occurs only in a narrow band of temperatures around zero degrees
Kelvin.
C. The synthesis of interstellar formaldehyde can be activated by means other
than cosmic rays.
D. Simple molecules can be synthesized by means of tunneling.
E. Classical chemical reactions do not occur at temperatures close to absolute
zero.
答案是A，解釋是從原文第三段 Cosmic rays (high-energy protons and other
particles) might trigger the synthesis of simple molecules 而來。 (取其相反)
但我覺得formation跟synthesis並不等價，formation指的是形成simple molecule
而synthesis指的是simple molecules互相結合後，生成的混合物
我個人覺得C比較合適，不知道有沒有大神能夠幫我解惑呢? :)
