判断正（A）误（B）
 
Do you use your right hands more or left hands more? Very few of us use both of our hands well. Most people use right hands. Only about five people of a hundred use left hands. New-born babies can take things with either of their hands, but in about two years, they like to use their right hands. Scientists don't know why this happens. They've studied it. They think our animal ancestors used their right hands, this may not be true. Monkeys are our closest relations in the animal world. 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 the left-handed ones. Next time you visit the zoo and watch the monkeys carefully. You'll see that some of them will use their right hands and others will use their left hands. But men use their right hands better and this makes life difficult for the left-handed ones. We live in a right-handed world.
 
Some scientists have found out that more of successful people are left-handed, but they don't know why. But they are working hard to discover the secret.
