Question

【题目】阅读下面的短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。

D

Most people around the world are“righthanded”. This also seems to be true in history. In 1979, scientists studied works of art made at different times from 1500 B．C. to the 1950s. Most of the people shown in these works are righthanded so the scientist guessed that righthandedness has always been common through history. Today, about 10% of 15% of the world's population is lefthanded.

Why are there more righthanded people than lefthanded ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hand and eyes work together, controls the left hand. The left side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists and doing problems. These findings show that more artists should be lefthanded, and studies have found that lefthandedness is twice as common among artists as among people in other jobs. No one really knows what makes a person become righthanded instead of lefthanded. Scientists have found that almost 40% of the people become lefthanded because their main brain is damaged when they are born. however, this doesn't happen to everyone, so scientists guess there must be another reason why people become lefthanded.

One idea is that people usually get righthanded from their parents. If a person does not receive the gene(基因)for righthandedness, he/she may become either righthanded or lefthanded according to the chance and the people they work or live with. Though righthandedness is more common than lefthandedness, people no longer think lefthanded people are strange or unusual. A long time ago, lefthanded children were made to use their right hands like other children, but today they don't have to.
