Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: We often consider plants as the furniture of the natural world. They don't move; they don't make sounds;they don't seem to act on anything. But as is often the case, plants talk to each other all the time. And the language is a chemical . Over the years, scientists have reported that different types of plants, from trees to tomatoes, give out chemicals into the air to help neighbouring plants. These chemical warnings can spread information about one plant's disease or infestation ,so other plants can protect themselves. But how plants receive and act on the information exactly is still mysterious . In this week's Science Magazine, researchers in Japan offered some explanations. They have found out one chemical message and traced it all the way from beginning to end. The scientists looked at tomato plants infested by a common pest . To start out,they grew plants in two separate plastic spaces connected by a tube . One plant was infested and placed upwind and the other was uninfested and placed downwind. The downwind plants were later exposed to the pest. The results showed that plants near sick neighbours before were able to protect themselves better against the pest. They found one chemical appeared more often in the exposed plants. The chemical is called HexVic. The scientists discovered where HexVic came from, and put it over healthy plants. Those plants were then able to produce HexVic. Researchers made sure that uninfested plants could fight off bugs and diseases. How do they know when to protect themselves? They are warned first by their friendly plant neighbours. It is not a simple story , and it may be happening in many other plants besides tomatoes. It may also be happening with more chemical signals that are still unknown to us. In a word, we know that plants not only communicate, but also look out for one another.
