In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

[Q]: Article: When a caterpillar feeds on a tomato leaf , the plant moves rapidly to meet with a defensive response , systematically releasing " proteinase inhibitors " -- proteins that interfere with the caterpillar's digestion -- throughout the plant , especially in the leaves . But how does the message get from the wounded leaf to the rest of the plant ? Most scientists believed the alarm was spread by chemical messengers until a team of researchers headed by David Weldon-- a biologist at the University of East Anglia in Norwich , England -- made a shocking discovery . An injured leaf , the researchers found , sends an electrical signal to warn neighboring leaves of upcoming danger . It's a " terribly tiny current " driven by an electrical potential difference of only 20 millvolts , says Weldon , who measured the voltage after electrodes were attached to the plant's surface . " Right now , all we can say is that there is a correlation , " Weldon notes . " If you wound the plant , you'll see an electrical signal accompanied by a biochemical response . " To learn more about the reaction , Weldon's team plans to insert electrodes within the pant tissue ( rather than on the surface ) to determine what's going on at the cellular level . The findings may help explain other mysteries surrounding plants . For example , many plants start to flower in springtime , as days grow longer , but plants sense the change in the day length through their leaves , while flowers begin to bloom at the buds . " There must be a signal from the leaf to the growing points , " Weldon says . " So far , no one has come up with a convincing chemical mechanism . Maybe an electrical signal is involved . "
Answer: They cure diseases by changing chemicals
[A]: What is the function of the " proteinase inhibitors " in tomato plants ?

[Q]: Article: I'm a Chinese student studying in Canada. I have been a boarder with the Carsons for more than a year and a half. The Carsons live in their own house, which has four bedrooms including the one in the basement which I live in. Judy does all the work in the house and Andrew is responsible for the work in the garden. When they go out in they evening, they often ask me to look after their children. Judy's parents, Mr. and Mrs. Morris, lived in another city. Judy was their only child and naturally they doted on Judy's children. They often sent the children presents. Last April Mr. Morris died. Now that Mrs. Morris was quite alone, I expected that Judy would want her to come and live with them. One day, Margaret, Judy's daughter, told me grandma was coming to live with them and her daddy and mummy would want my room back. The news didn't surprise me and the next day I went to Judy and asked her about it. I said I couldn't think of living in their basement room any longer if it was needed for Mrs. Morris. Judy seemed surprised at first. Then she told me there was no deed for me to move, for they hadn't yet come to any decision about her mother coming to live with them. "Naturally I'm worried about my mother. She has been in poor health." She smiled sadly and added. "To be honest, Andrew and my mother have never got on well. We'll wait a bit and see what happens. Perhaps Mohter will be all right living herself, or perhaps they will both change their minds." That was six months ago. During this time I've heard that Mrs. Morris has had two illnesses and that her health has got worse. A nursing home was mentioned once but Mrs. Morris refused to go there. So up to now she's still living alone and I'm still living in the basement room.
Answer: He is a student who pays to live and have meals at the Carsons' house.
[A]: What is the relationship between the speaker and the Carsons?

[Q]: Article: Glynis I piled on the pounds and I couldn't lose them. Then I joined a slimming club. My target weight was 140 pounds and I lost 30 pounds in six months. I felt great and people kept saying how good I looked. But Christmas came and I started to slip back into my old eating habits. I told myself I'd lose the weight at slimming classes in the next year, but it didn't happen. Instead of losing the pounds, I put them on. I'd lost will power and tried to believe the saying that fish and chips didn't make any difference but the scales don't lie. Roz To be honest, I never weigh myself any more. I've leant to be happy with myself. It seemed to me that I would feel sorry about every spoonful of tasty food that passed my lips. My idea is simple. You shouldn't think too much about food and dieting. Instead, you should get on with life and stop dreaming of a super-thin body. This is obviously the size I'm meant to be and, most of all I'm happy with it. Lesley I was very happy about winning Young Slimmer of the Year. I'd look in the mirror, unable to believe this slim lady was me! That might have been my problem-perhaps from then on I didn't pay any attention to myself. Winning a national competition makes everything worse, though because you feel the eyes of the world are fixed upon you. I feel a complete failure because I've put on weight again. Ros Before moving in with my husband Gavin, I'd always been about 110 pounds, but the pleasant environment went straight to my waist and I put on 15 pounds in a year. Every so often I try to go on a diet. I always do well in the first few days, then end up having the children's leftovers or eating chocolate happily-my weakness. I'd like to be slim. I decided to take more exercise when my kids are older.
Answer: Their figure.
