Article: When an ant dies, other ants move the dead insect out. Sometimes, the dead ant get moved away very soon--within an hour of dying. This behavior is interesting to scientists, who wonder how ants know for sure--and so soon--that another ant is dead. One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist. Choe found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, "I'm dead--take me away." But there's a _ to Choe's discovery. Choe says that the living ants--not just the dead ones--have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it's telling other ants that it's dead. What keeps ants from dragging away the living ants?Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, "Wait--I'm not dead yet." So Choe's research turned up two sets of chemical signals in ants: one says, "I'm dead," and the other set says, "I'm not dead yet." Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, for example, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive. Choe suspects that when an Argentine ant dies, the chemical that says "Wait-I'm not dead yet" quickly goes away. Once that chemical is gone, only the one that says "I'm dead" is left. "It's because the dead ant no longer smells like a living ant that it gets carried to the graveyard, not because its body releases new unique chemicals after death," said Choe. When other ants detect the "dead" chemical without the "not dead yet" chemical, they drag away the body. Understanding this behavior may help scientists figure out how to stop Argentine ants from invading new places and causing problems. Choe would like to find a way to use the newly discovered chemicals to spread ant killer to Argentine ant nests. The ants' removal behavior is important to the... Question: The result of the research can be used to _ . Yes or no, is the answer "prevent further expansion of the ants' territory"?

Article: While they were almost unknown twenty years ago, it seems that mobile phones these days are part of everyone's life. However, as with other inventions such as the television and the computer, they are a double-edged sword, inviting both supporters and opponents, especially in regard to their use in public places like restaurants and cinemas. One of the strongest arguments in favor of forbidding mobiles in public places is the trouble they cause to other people. For example, although we are often asked to turn off our phones when in a cinema, the film that we are watching is often interrupted by the sound of at least five rings. To make it even worse, some people insist on continuing their conversation, even though hundreds of people can hear what they say, which often drowns out the voice from the film. As a result, many people would welcome a ban on mobile phones in places where they might disturb other people. On the other hand, there are a number of arguments against such a ban. It is difficult to stop people bringing with them their mobile phones in public places, making it almost impossible to call for a ban. Some people would see this as an infringement of their rights, while other people would say they need them in case of an emergency. Despite being asked to silence their phones, some people insist on leaving them on. It seems to me that a ban on mobile phones would not have any result in the end. People will find a way to escape a ban. Nevertheless, people should be discouraged from using them in public places, unless it is highly necessary. They should be made to know that it is bad manners to use them in certain places or at certain times. Of course, there will always be someone who thinks their call is more important than others' peace and quiet! Question: Among those who are against a ban, some believe that _ . Yes or no, is the answer "it is their right to use their mobiles in public places"?
**Answer**
No
