  But一词对上文的结论给予了否定,所以其后的内容正是"right-handed" hypothesis的problem所在。故A选项正确。

  A To explain why he prefers to paint left profiles
  B To point out a difference between adult portraits and baby portraits
  C To point out a fact that contradicts the "parental imprinting" hypothesis
  D To provide support for the "parental imprinting” hypothesis
  答案:D
  破题关键词汇:why

  学生说这话之前,教授说“Well, another theory is what’s known as the parental imprinting hypothesis, which proposes that people are more used to seeing….”
  所以学生说的这句话是为了support教授的"parental imprinting” hypothesis,故D选项正确。
