[Q]: 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.
Answer: Some factors cause indoor air pollution.
[A]: What is the main idea of the passage?

[Q]: Article: Despite organized anti-bottled-water campaigns across the country and a noisy debate about bottled water's environmental effect, Americans are buying more bottled water than ever. --------------------------------------------------------------------------------------------------- Why do so many people seem to think they should have any input on what other Americans choose to buy or do? If they want to buy bottled water, let them. If they want to eat fast food, let them. If they want to smoke pot, let them. ----Barackalypse People just get tired of paying for others' bad behavior. If many people eat too much fast food, you pay higher insurance bill. If many people frequently buy bottled water, your trash bills go up and landfills fill up quickly. It's about personal responsibility, which really should be a basis of our society. ----Bdbr So? This is the price you pay to live in a free society. You want to control the life of another just so you can save a little money? What would you say when someone do the same to you? ----Norman619 I'm just glad there are still people who still believe personal responsibility is a good thing. We make your life cheaper and less bothersome. ----Yoyo What a waste of money. It's fine when you're on the road and you need a cold drink, but people who buy cases of bottled water for home are completely crazy. ----Agmlauncher I wish we all can find a way to improve things and benefit from this. The environment needs a lot of help but businesses will always work on what people would need and demand. Is this part of the trade-off? Hope we can find better ways. ----Skipweis

[A]: Which of the following is TRUE about bottled water in America?

[Q]: Article: Our children grew up on peanut butter and jelly sandwiches. Even my husband and I sometimes ate one secretly at late night with a glass of milk. It was too delicious and tasty. My mother-in-law was the jelly maker in this family. The jelly was made of either grape or blackberry. The only job I did to the jelly making was to save baby food jars , which my mother-in-law would fill with the tasty gel , pack them up and send back to our home. For the past 22 years of my married life, whenever I wanted to make a peanut butter and jelly sandwich for ourselves, all I had to do was reach for one of those little jars of jelly. It was always there. This past December, my mother-in-law passed away. Among the things in the house to be divided by her children were the remaining canned goods in the pantry . When my husband brought his jars home, we carefully put them away in our pantry. The other day I reached in there to get jelly for a quick sandwich, and there _ was. Sitting all alone on the far side of the shelf was a small jar of grape jelly. As I picked up the jar, I suddenly realized something that I had failed to see earlier-this was the last jar we would ever have from my mother-in-law. Although she had been dead for nearly a year, so much of her had remained with us. Our children had never known a day without their grandmother's jelly. It seems like such a small thing, and most days it was something that was ignored. But today it seemed a great treasure. No longer was it just a jar of jelly. It was the end of a family tradition. I believed that as long as it was there, a part of my mother-in-law would always live on.
Answer: Because it was very delicious and nice.
[A]:
Why did the couple eat the jelly secretly at late night?
