阅读下列短文，从各题所给的A、B、C三个选项中，选出最佳选项。

　　Have you seen Avatar(《阿凡达》)? It's a popular 3D movie, and you may have to wear 3D glasses to see it．The 3D glasses make the images(图像)from the movie look as if they are coming straight at you．

　　More and more 3D movies are coming to theaters．Some say that 3D TV sets will come into our homes in the near future．Three－dimensional technology can make TV and movies more exciting．But people with eye problems may get headaches if they spend too much time watching 3D movies．Why?

　　When we look at an object(物体), each eye sees it at a different angle(角度)．Our eyes send the two images to our brain(大脑), and the brain puts them together．3D technology uses two film projectors(投影机)．One projects a left eye image and the other projects a right eye image．3D glasses allow us to see a different image in each eye．So, when we are watching a 3D movie, our brain can't put together the images sent to our eyes．The brain needs to work harder at “reading” the images．That makes it easier for these people to get dizzy(头晕的)or develop headaches．A famous eye doctor said if your eyes can't focus(聚焦)on the same object at once, you will have trouble watching 3D movies．

　　What do Napoleon, Clinton and Wang Nan have in common? They are all left-handed. Today about 15％ of the number of people are left-handed. But why are people left-handed? The answer is the way the brain works.

　　The brain has two halves－the right half and the left half. The right half controls the left side of the body, and the left controls the right side of the body. So right-handed people have strong left brain, and left-handed people have a strong right brain. The two halves of the brain are about the same size. But each side controls different things. The left side controls language, maths and logic(逻辑). When you remember new words, or when you put things in order, you use your left side. The right side of the brain controls your love of art, colour and music. It is also good at recognizing faces. This does not mean that all artists are left-handed and all accountants (会计)are right-handed. Some right-handers have a strong right brain, and some left-handers have a strong left brain.

(1) The phrase “in common” in the first sentence means ________ .

[　　]

A. the same

B. different

C. strange

(2) People are fight-handed or left-handed is mostly decided by ________ .
