Q: Read the article and select the best answer. Article: About ten men in every hundred have the trouble of color blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all ,it is safer to be driven by a woman. There are different kinds of color blindness. For example, a man cannot see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can't tell the difference between blue and green. Only a few unlucky men may see everything in shades of green-- a strange world indeed. Color blindness in human beings is a different thing to explain. In only one eye there are millions of very small things called "cones " . These help us to see in the bright light and to tell differences between colors. These are also millions of "rods" ,but these are used for seeing when it is nearly dark. They show us shapes but not colors. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky. With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of the rods we can see shapes at night. Question: With the help of the "cones", we can _ . Options: A: tell different shapes B: kill insets C: see in the dark D: tell orange from yellow
A: D

Q: Read the article and select the best answer. Article: Many people think the dinosaurs were the biggest animals that ever lived. They are wrong. The world's biggest animal is still living and it lives in the ocean . It is the blue whale . Blue whales can be as long as 30 meters and weigh as much as 1,000 kilos. The largest dinosaurs weighed only 500 kilos. The whale is not only the world's biggest animal; it is also one of the cleverest. We know that whales can talk with each other, but we do not know what they are saying. Maybe one day we will learn how to talk with whales, and then they will be able to tell us about themselves. Whales live in the ocean, but they don't _ eggs like fish do. They are mammals . They give birth to babies and have milk inside their own bodies to feed them. Humans are also mammals. Sadly, there are not many kinds of whales left. People have killed them for food and other things for a long time. Now there are laws to stop people killing most kinds of whales. So maybe there will be more of them in years to come. Question: The article mainly talks about _ Options: A: the world's biggest animal B: lots of stories about whales C: laws to stop people killing whales D: the differences between dinosaurs and whales
A: A
