An "empty" drinking glass and an "empty" room, to give two examples, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass. Air, as a gas, has no definite shape, but, because it is matter, it takes up space. It is easy to prove that air is something that takes up space. _ a dry handkerchief into the bottom of a glass so that it will not fall out when the glass is turned upside-down. Push the upside-down glass; hold it straight into a jar of water till the glass is completely covered. When the glass is taken out of water, the handkerchief will be dry. The air inside the glass takes up space and keeps the water from coming in.

Read the following article and select the best answer. Article: Almost 80% of the Americans have stated their opposition to cloning pet animals such as cats and dogs, yet companies still try to make a business out of selling cloned pets. Pet cloning has been promoted as a way to "bring back" or "copy" a beloved companion animal. However, studies have shown that cloning remains an experimental technology with many failures. Behind each lovely picture of a cloned cat or dog lie hundreds of animals that were kept in lab cages, receiving bad treatment to produce just that one cloned animal. For all that, you end up with a cloned animal who is unlikely to appear like the original physically or behaviorally and may experience serious health problems. Also, while pet cloning companies are charging customers up to $150,000 for a cloned pet, millions of homeless animals of the same species are available in US animal shelters for around $100. Unfortunately, most of these animals are killed for lack of adopting homes. With No Pet Cloning campaign, the American Anti-Vivisection Society (AAVS) tries to protect both animals and people from harm. They campaigned until the US companies that sold cloned animals closed their doors. First it was Genetic Savings & Clone Inc. and then it was BioArts International. When BioArts was closed, its owner, Lou Hawthorne, finally had to _ the problems of pet cloning. According to Hawthorne, he has seen numerous failures during his pet cloning attempts, "One clone----which was supposed to be black and white----was born greenish-yellow where it should have been white (we still have no good explanation for how that happened)." The AAVS is educating the public about the animal suffering and is seeking regulation of cloning activities. They will continue to take the lead in protecting animals from the threats of pet cloning. Question: According to the passage, companies keep on selling cloned pets to _ . - carry on scientific studies - get economic interests - protect pet animals - comfort animal lovers
(Answer)
get economic interests

But he still felt cold and uncomfortable. The man was on his way to a camp near Henderson Creek. His friends were already there. He expected to reach Henderson Creek by six o'clock that evening. It would be dark by then. His friends would have a fire and hot food ready for him. A dog walked behind the man. It was a big gray animal, half dog and half wolf. The dog did not like the extreme cold. It knew the weather was too cold to travel. The man continued to walk down the trail. He came to a frozen stream called Indian Creek. He began to walk on the snow-covered ice. It was a trail that would lead him straight to Henderson Creek and his friends. As he walked, he looked charily at the ice in front of him. Once, he stopped suddenly, and then walked around a part of the frozen stream. He saw that an underground spring flowed under the ice at that spot. It made the ice thin. If he stepped there, he might break through the ice into a pool of water. To get his boots wet in such cold weather might kill him. His feet would turn to ice quickly. He could freeze to death. At about twelve o'clock, the man decided to stop to eat his lunch. He took off the glove on his right hand, opened his jacket and shirt, and pulled out his bread and meat. This took less than twenty seconds. Yet, his fingers began to freeze. He hit his hand against his leg several times until he felt a sharp pain. Then he quickly put his glove on his hand. He made a fire, beginning with small pieces of wood and adding larger ones. He sat on a snow-covered log and ate his lunch. He enjoyed the warm fire for a few minutes. Then he stood up and started walking on the frozen stream again. A half hour later, at a place where the snow seemed very solid, the ice broke. The man's feet sank into the water. It was not deep, but his legs got wet to the knees. The man was angry. The accident would delay his arrival at the camp. He would have to build a fire now to dry his...
