Passage Five 5
Which of your two hands do you use more Very few of us can use both hands equally well. Most of us are right-handed. Only about five people out of a hundred are left-handed. New-born babies can take hold of things with either of their hands, but. in about two years they usually use their right hands. Scientists have found that monkeys like to use one of their hands more than the other, but it can be either hand. There are as many right-handed monkeys as there are left-handed ones. Next time when you visit a zoo, you’ll see that some of them will use their right hands and others will use their left hands. But most of the people use their right hands better and this makes life difficult for those left-handed people. We live in a right-handed world.

Monkeys （　）
A. are left-handed
B. can use both hands equally well
C. are right-handed
D. like to use one hand more than the other
