Article: Every year gray whales swim a 10,000 miles round-trip, from the cold waters near Alaska, down the coast of North America to the warm waters near Mexico, and back again. It is one of the longest migrations of any mammal. All day, all summer long, in the cold waters near Alaska, gray whales eat and eat. Instead of teeth, gray whales have baleen, they are used to getting food from ocean water. They get big mouthfuls of muck from the ocean floor, then push that muck right back out through their baleen. The mucky water flows through, but tiny animals get trapped in the baleen and _ . When the water starts to freeze, the whales begin their long trip south. They swim night and day, without stopping to eat or rest. During the long journey, migrating whales may push their heads out of the water to see where they are. Two months later, the whales reach Mexico. Babies are born here in warm, shallow waters called lagoons. Ocean lagoons have no food for the adults, but the babies are safer here than in the open seas. All winter the babies grow big and strong. In spring first the dads and teenagers leave the lagoons, then the moms with babies. Migrating gray whales swim close to shore, especially moms with babies. The ice is melting up north, and it's time for the hungry whales to make the long journey back to their summer feeding grounds. Question: During their long journey to Mexico, gray whales _ . Yes or no, is the answer "always swim under the ocean"?
No

Q: Article: A wise man once said that the only thing necessary for the victory of evil is for good men to do nothing. So, as a police officer, I have some urgent things to say to good people. Day after day my men and I struggle to hold back a tidal wave of crime. Something has gone terribly wrong with our once-proud American way of life. It has happened in the area of values. A key ingredient is disappearing, and I think I know what it is: accountability. Accountability isn't hard to define. It means that every person is responsible for his or her actions and liable for their consequences. Of the many values that hold civilization together --- honesty, kindness, and so on --- accountability may be the most important of all. Without it, there can be no respect, no trust, no law --- and, ultimately, no society. My job as a police officer is to impose accountability on people who refuse, or have never learned, to impose it on themselves. But as every policeman knows, external controls on people's behavior are far less effective than internal restraints such as guilt, shame and embarrassment. Fortunately there are still communities --- smaller towns, usually --- where schools maintain discipline and where parents hold up standards that declare: "In this family certain things are not tolerated --- they simply are not done!" Yet more and more, especially in our larger cities and suburbs, these inner restraints are loosening. Your typical robber has none. He considers your property his property; he takes what he wants, including your life if you annoy him. The main cause of this breakdown is a radical shift in attitudes. Thirty years ago, if a crime was committed, society was considered the victim. Now, in a shocking reversal, it's the criminal who is considered victimized: by his underprivileged upbringing, by the school that didn't teach him to read, by the church that failed to reach him with moral guidance, by the parents who didn't provide a stable home. I don't believe it. Many others in equally disadvantaged... Question: Compared with those in small towns, people in large cities have _ . Yes or no, is the answer "less self-discipline"?
A: No

*Question*
Article: When you choose a freezer, remember it's probably going to be with you for a long time. So it's important to know which freezer is right for your needs. First, decide if you want an upright or chest model. Uprights are more convenient. Their storage space is more accessible and they take up less floor area. However, chest models are more energy-efficient because less cold air escapes when they are open. If you are buying an upright, you'll have to choose between frostless or manual defrost . Chest freezers are always manual. Frostless freezers automatically defrost at present intervals and remove the water. Manual models must be defrosted by hand every few months or whenever frost pile up to about a quarter of an inch. To help your freezer reach a ripe old age, try to find a spot that's cool, dry, and away fromdrafts . Drafts and heat will raise the freezer's cabinet temperature, which makes it work harder to keep cool. That means wasted energy. That means wasted energy and a shortened life. Dry air is important because highhumidity can cause the freezer to rust outside and frost up inside. With proper care, a freezer can serve you for 15 years or more. Regular cleaning and simple maintenance will help it maintain a zero-degree temperature and keep it smelling fresh and looking almost new. Frostless models requires less care than manual defrost freezers. The inside of a frostless unit should be washed periodically with warm water and baking soda or a mild soap, rinse, and dried. Good habits go a long way toward a freezer that runs efficiently. To get the most from your freezer, check regularly to make sure it's providing a true zero-degree temperature. Keep the freezer at least three-quarters full. The emptier it get, the more energy is wasted. If more than three pounds of food per cubic foot of storage space is added every 24 hours, the resulting high or low temperature can damage the food. Question: In order to get the best results, you should _ . Yes or no, is the answer "keep the freezer at least 75% full"?
**Answer**
Yes
