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.

Ex Input:
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 . "

Article: I had lunch with a friend of mine the other day and she said something that I found surprising: "Work is paid slavery." My friend wanted more control over her work hours, income, etc., but you can imagine that if "work is serving someone," she won't have much luck until that belief changes. When I asked her where that belief came from, she said her father. Most of us spend many of our waking hours at work. How we think about those hours will determine how good or bad we feel about our lives. How would you complete the sentence: "Work is...."? How many of us say that work is fulfilling? How many say work is fun? Changing Limiting Beliefs Almost everyone I talk to has limiting beliefs about money or work. I worked with my friend using the walking belief change described in Debug Your Mental Software. When it came time to come up with a new belief, she struggled. She even asked me: "What's the opposite of slavery?" So strong was the old belief that she couldn't think of the opposite. What's Your Work Belief? If you think work is bad, you'll end up working in an unfulfilling job regardless of how much it pays. If you think work is freedom, you'll enjoy your work because it fulfills you. I call it "soul work." If you're doing the work you love, it will be energizing, freeing. Much of our work ethic starts in childhood by watching our parents. How did they talk about work? Did they hate it, or did they love it? The truth is probably somewhere in between. Many of us say we don't want a job "like my parent had" or a job where they're stuck inside a small room. But many of us end up with jobs like that. Sometimes it's how we approach the tasks of our jobs that make the difference. It's possible to make even the most ordinary job meaningful and fulfilling. If it isn't possible for you to do that, then it is time to think about "evolving out of the job". Sometimes just quitting a job because it's boring is the wrong thing to do, but thinking about where you want to be and if you need more education is a good idea. Some young people seem to have trouble starting jobs or finishing college. Has our economy discouraged them? A recent movie I saw had a grown man (over thirty) telling his friends that he's a "stay-at-home-son." Truth is sometimes stranger than fiction. I had breakfast at my local Perkins yesterday. Kristin took my order. She was bubbly and full of energy compared to the other waitresses. I watched as she remembered everything a family of four staying at a neighboring hotel had ordered the day before. Kristin loved people and loved her job. She has the kind of attitude and work ethic that employers crave. What's your work belief? Does it limit you? Could you tune it up to live a better life right now? If most of us are going to spend 30 years working, shouldn't we try to make it enjoyable? Could it be that work is freedom or right work is energizing or something even better?

Article: *What prevents depression:tea,coffee or hot chocolate? Women who drink for or more cups of coffee a day are a fifth less likely to become depressed.Drinking two or three cups reduces the risk by 15 percent. This is the result of a study of 51,000 women over ten years, published in the Journal of the American Medicine Association. One theory is that caffeine reduces the effect of the chemical adenosine in the brain, which can make us feel sleepy by slowing down nerve cell activity. Some anti-depressants also work by blocking the adenosine receptors. Coffee was found to be far more influential on depression levels than hot chocolate or tea due to the high caffeine content. *How many eggs can we healthily eat: one a day or two a day? Neither-eat them freely. We've long been warned to stick to two or three eggs a week because of their high cholesterol content. But according to the Food Standards Agency, there is no recommended limit to how many eggs we can healthily eat, unless you have been told to cut down by your doctor. There is no evidence that eating eggs raises cholesterol levels, and researchers found that eggs contain less cholesterol than in the past because hens are no longer given bone meal, which was banned in the 1990s after the BSE cresis. Research by the British Egg Council found that a medium egg gives you around 100 mg of cholesterol, a third of the 300mg recommended daily limit.
Answer: Coffee.
