Read the following article and select the best answer. Article: Scientists are closely concerned with the structure of buildings and with the quality of building materials. The World health Organization (WHO) observes that the introduction of air conditioning and energy conservation measures have been accompanied by growing problems of indoor air quality. Some pollutants arise from insulation products, some from moving cars, and others from modern housing materials. As many Europeans spend up to 90% of their lives in buildings, the health effects of the indoor climate are very important. Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde . Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes. Paint, lacquer, etc. can also release dangerous gas into indoor air. Construction materials can cause serious damage, especially when they contain asbestos . Asbestos is naturally present in rock formations worldwide. It belongs to a family of mineral substances made up of solid, non-combustible fiber. These properties make asbestos a highly sought-after construction material. As early as 1931, however, public health officers in the prefix = st1 /United Kingdomrevealed the connection between breathing in asbestos dust and such diseases as lung cancer. The land on which a building is sited may also contribute to pollution. Some kinds of granite or similar rocks contain traces of radium. As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms. The better the homes are insulated, the more is the dangerous gas in indoor air. The main effect of this dangerous gas on health is to increase the risk of lung cancer. Question: Why is asbestos a sought-after building material? - It is a kind of insulation foam. - Asbestos will not give out dangerous gas. - This material is not easy to catch fire. - It is rarely present in rock formations.
This material is not easy to catch fire.

Steve has just lost his wife to cancer and everything they had is gone due to the treatment. He now lives in the shelter for the homeless. So we know each other. Just like other homeless people, he didn't think he needed anything. But once he mentioned to me he needed eye glasses. His voice hesitated a bit, he looked down, and it appeared like he thought such a request was just a dream. Too much to hope for? It was as if his wish were known by me only. I submitted an application for him to a program that is supposed to provide a free eye examination and glasses. Three months later, I phoned to ask what was up with the appointment but they told me there was a cash flow problem until late summer. Steve showed disappointment, thanked me and started to walk away. I said, "Hold on, I will figure out a way to get you an eye examination and glasses." His face lit up a tiny bit. He had seen some of the things I have done for other people in our shelter and to me it looked like he might have a line of hope. I took a picture of him and posted his picture and his story in the Twitter. In about 4 days, eight people from around the world donated $25 each and one person donated $40 and I made up the rest to get him an eye exam and glasses. Steve picked up his glasses on Wednesday: May 11th, 2011. Today Steve has returned to a previous job he had in a nearby car wash. Because he now has glasses he will be able to see what he is doing while cleaning the vehicles. He is starting a second job at a pet center next week! Question: The program failed to satisfy Steve because _ . - it was already out of business - it had some trouble in finance - Steve didn't submit the application himself - it's not designed for people like Steve
it had some trouble in finance

Q: Read the following article and select the best answer. Article: A close friend of mine lives with six hundred wild animals on the Greek Island of Kyklos.Ever since he left school (where I first knew him),he has travelled all over the world collecting animals for his very own zoo.He hoped to collect at least two examples of every sort of animal on his island before the Great Flood. But the flood that my friend was afraid of was a flood not of water, but of people. I expect you have heard of my friend: he writes books about his travels,and about the wild and wonderful animals that he collects. The money from the books helps to pay for all the food that these animals eat. My friend told me that when he was out looking for water last week,(there is not enough water on the island,though there is plenty all round it,)he found oil.He needs money for his travels,and for his zoo,and a little oil would buy enough water for a lifetime;but he knows that if he tells anybody else about it,it will be the end of his zoo, and his life's work. So,if I know my friend,he will not tell anybody (but you and me)about what he found--because oil and water do not mix. Question: Since he left school _ . - he has collected books about every sort of animal - he has lived in zoos all over the world - he has lived all the time on a Greek island - he has travelled all over the world collecting animals
A: he has travelled all over the world collecting animals

Q: Read the following article and select the best answer. Article: When Dr Jane Goodall was a kid growing up in England, she dreamed of one day living among wild animals.
