input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: In nature, you may see many insects and animals of different colors. Have you ever wondered why? Locusts are super delicious food for birds,but it is not always an easy job for birds to catch them.It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops . When crops are young,locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do. Brown bears,tigers and other animals move quietly through forests. They can't be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to _ they have to hide themselves in the daytime and appear only at night. Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over , its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all. Options: A Some insects and animals have different skills. B Some insects and animals are clever than we think. C Some insects and animals use colors to protect themselves. D Some insects and animals can get used to the environment easily.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Is there intelligent life on other planets? For years, scientists said "no." or "we don't know." But today this is changing. Seth Shostak and Alexandra Barnett are astronomers . They believe intelligent life exists somewhere in the universe. They also think we sill soon contact these beings(;). Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. "This is long enough for other planets to have intelligent life," say Shostak and Barnett. The second reason is size--the universe is huge. "Tools like the Hubble Telescope have shown that there are at least 100 billion galaxies," says Shostak. "And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth." In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes allow scientists to discover smaller planets--the size of Mars or Earth--in other solar systems. These planets might have intelligent life. Have beings from space already visited Earth? "Probably not," says Shostak. "It's a long way away. However, intelligent beings may contact us in other way, such as radio signals . In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other." Options: A astronomers B farmers C singers D drivers Answer: A astronomers Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: If you ask me to tell how to get along in the United States, I think the following "do's" and "don'ts" would be helpful. Generally speaking, it isn't easy to find anyone to talk to in a busy city, so you should try to do the following. First, get or borrow a dog! Walk him several times a day! Americans love dogs and cats and usually stop to talk to anyone with a dog. Then, try to eat in a restaurant. People generally share the same table and will sometimes talk to you if they see you are new there. Next, take your dirty clothes to a laundry ! It takes about an hour to wash and dry them and people there often pass the time talking with each other. Always ask for information from a woman if you are a man, and from a man, if you are a woman! Learn to say, "Please" "Thank you" and "You're welcome" and use them all the time! There are some things you shouldn't do. Don't tell the truth when people ask, "How are you?" The only answer they want is "Fine". Never ask people their age--especially women! Everyone wants to be young. Don't tell heavy people they are fat. Tell them they are losing weight. Everyone wants to be thin. Don't be late when meeting people! When someone says six o'clock, be sure to be there by six. Americans respect time and want everyone to be "on time". Options: A can be there at any time B may be there a little late C had better arrive every early D should be there at the right time Answer: D should be there at the right time Question:
