[EX Q]: Article: What a great project this is, building your own greenhouse! If you're a gardener, then a greenhouse is necessary no matter where you live. As long as you've got some good plans, it's possible to build a backyard greenhouse within just a few days. It's a great way to impress the neighbors! Metal greenhouses are practical, I agree, but they look ugly. If you build your own backyard greenhouse from wood, you'll end up with a lovely looking Victorian-style greenhouse, which will last very long if you treat it with the correct wood protection. Of course you'll save a lot of money in the process too. How much exactly? It's difficult to say as it depends on how much glass costs where you live. After all, there isn't much wood required, as it's only the actual frame that is wooden. To make sure you save the most money, it's best to take your plans to wherever you plan to buy your materials. That way you won't end up wasting any money on unnecessary materials. To be honest, saving money is not the main reason for building your own greenhouse. It's the fun you'll get from building it and the pleasure you'll get from showing it off to your friends and family that makes the project worth doing. Nothing beats the feeling when someone asks you where you bought something and you turn around and say "Oh, actually, I built it myself!" That feeling is priceless! You'll never feel like that over something you've bought!

[EX A]: C

[EX Q]: Article: What if it isn't a dog-eat-dog world? What if caring for a dog or for a mom with Alzheimer's makes you stronger and allows you to live longer? Researchers at the University of California, Berkeley are challenging our long-held belief that humans are born to be selfish. Darwin's theory of evolution by natural selection was misunderstood by his male followers, the researchers say. Rather than "every man for himself", Darwin believed that humans are successful as a species precisely because of our educational, selfless and sympathetic characteristics. Why has it taken so long for Darwin's central revelation to be properly understood? "We've had too many men in social science," Berkeley psychology professor Dacher Keltner told me in an interview. "Female scientists acknowledge that caring for people is part of human nature according to the research, which shows the human ability to care exists in our brains and nerve systems." In my bookPassages in Caregiving, I urge women who take the whole responsibility for taking care of an elderly parent or a sick relative to build a "Circle of Care". Reach out to your brothers and sisters, friends, neighbors and community volunteers to help you care, because no one can perform this overwhelming role alone. You will be as shocked as I to learn how the most selfless caregivers are rewarded with longer life. Sympathy is not a woman's word. In fact it makes all of us stronger under stress and more highly respected by our peers. For so long we have repeated the false saying "Nice guys finish last". But the 40 richest Americans committed to doing good by donating half their fortunes are _ . So here is my new explanation:Nice guys die last.
Question: InPassages in Caregiving, women are advised to _ .
Options: (A) share the responsibility of caring with others (B) take good care of themselves (C) learn how to live a longer life (D) help as many people as possible
[EX A]: A

[EX Q]: Article: Getting in touch with nature can help keep people fit, reducing the burden of sickness on the health service, conservation experts say. Natural England is starting a campaign to get people to spend more time outside among the country's wildlife and natural environment. The aim of the campaign is to get people to have more contact with nature by promoting green spaces and encouraging health professionals to incorporate (......) the thought into the advice and care plans that they give to patients. Being close to nature can cut stress and increase physical activity. Dr. William Bird from Natural England said: "Increasing evidence suggests that both physical and mental health are improved through contact with nature. Yet people are having less contact with nature than at any time in the past. This has to change. Children with attention disorders have been shown to improve when they have contact with nature. People recovering from operations have been shown to need fewer painkillers if they look out at green fields." He also said people were more likely to keep up with their regular exercise in natural settings, rather than in a gym or leisure centre. Natural England is working with the BBC and more than 300 partners to promote its campaign, which will be the first of four campaigns to get people more involved in nature. Liz Cleaver, from the BBC, said: "These campaigns now provide the public with the opportunity to get outside and to get actively involved in nature close to where they live. That's great for wildlife --but it's also fantastic for everyone's health and well-being." The campaign has also received support from the government. Dr. Fiona Adshead, England's deputy chief medical officer, said: "I welcome Natural England's commitment to encourage and enable people to make use of the country's outdoor space for physical activity."
Question: The purpose of the campaign is to _ .
Options: (A) give people more chances to be close to nature (B) ask health professionals to offer useful advice (C) protect the country's wildlife and environment (D) encourage people to keep regular exercises
