     Tom is seven. He goes to school every day. The school is near his home. So he goes there on foot

and comes back home on time (准时).  But today he is late. His mother asks him, "Why are you late

today?"  "I was in the headmaster's office (校长办公室). "  "Why did you go to the headmaster's

office?" "Because my teacher asked us a question in class, and nobody (没人) could answer it, but me."

"It's good to answer the question." "But the question was 'Who put ink on my chair? "'

某类鸟有两个品种：有冠的和无冠的。经常生活在一个仅有有冠的鸟的群体中的鸟，或者经常生活在一个都无冠的鸟的群体中的鸟，在选择配偶时，倾向于选择与其群体有一致特征的对象。而一只在有冠鸟的群体中长大的鸟，无论它自己有冠或无冠，都会选择一个有冠的配偶。这表明这种鸟选择有冠或无冠的配偶的偏好是后天获得的，而不是由先天的基因决定的。 如果以下哪项陈述为真，能对上文中的论述提供最强的支持

A．其他种类的鸟也倾向于选择具有某种外形特征的配偶。

B．通常情况下，有冠的鸟和无冠的鸟在行为上几乎没有什么差别。

C．如果一只有冠的鸟在笼中独自长大，当它被放人一个既有有冠鸟，也有无冠鸟的群体中时，它倾向于找一个有冠的配偶。

D．一只生长在既有有冠鸟，也有无冠鸟的群体中的鸟，在找配偶时对有冠或无冠的特征没有偏好。
