Article: TOKYO, JAPAN--What do you do when you see a cockroach ? Do you hit it with a newspaper? Do you step on it? When researchers at Tokyo University see a cockroach, they take the remote control and make the cockroach turn around, run left or right, or go forward. These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has in it a microprocessor .Then researchers can send signals from the remote control to the pack. The signals control the movements of the cockroaches. Why does anyone want to control a cockroach? "Insects can do many things that people can't," says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble to look for people or move under doors to find information about someone. This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $ 5 million for this research. First, the researchers breed hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae . They put small packs where the antennae were. The packs weigh about three grams, or about two times the weight of the cockroaches themselves. "Cockroaches are very strong," says Ralph Holzer, who is a researcher at Tokyo University. "They can lift 20 times their own weight. " With a remote control, the scientists send signals to the packs. When a cockroach gets the signal, it moves. The problem is that the cockroaches don't always move in the right direction. Question: What can cockroaches do to help people? Yes or no, is the answer "They can search for those people in rubble after an earthquake."?
(Answer)
Yes

Ques: Article: Never go into a supermarket hungry! This is a good piece of advice. If you go shopping for food before lunchtime, you'll probably buy more than you plan to. Unfortunately, however, just this advice isn't enough for shoppers these days. Modern shoppers need an education in how and how not to buy things at the store. First, you check the weekly newspaper ads. Find out the items that are on sale and decide if you really need these things. In other words, don't buy anything just because it's cheaper than usual! Second, never let "New and Improved!" or "All Natural" on the front of a package influence you. Instead, read the list of contents on the back. Third,compare prices: that is, you should examine the prices of both different brands and different sizes of the same brand. Another suggestion for shoppers is to buy ordinary items instead of famous brands. Ordinary items in supermarkets come in plain packages. These products are cheaper because producers don't spend much money on packing or advertising. However, they are still of high quality. In the same way, in buying clothes, you can often find high quality and low prices in brands that are not famous. Shopping in discount clothing stores can help you save a lot of money. Although these stores aren't very attractive, and they usually do not have individual dressing rooms, not only are the prices low, but you can often find the same famous brands that you find in high-priced department stores. Wise shoppers read magazine ads and watch TV commercials ,but they do this with one advantage: knowledge of the psychology behind the ads. In other words, will-informed shoppers watch for information and check for misinformation. They ask themselves questions: Is the advertiser hiding something in small print at the bottom of the page? Is there any real information in the commercial, or is the advertiser simply showing an attractive image? With the answers to these questions, shoppers can make a wise choice. Question: The author gives _ suggestions to the shoppers in the passage. Yes or no, is the answer "Six"?
Ans: No
