Question: Read the following article and answer the question. Article: It's a time when school,homework,active social lives and pare-time jobs keep teenagers busy from early in the morning until late at night.They are likely to try to make up for a lack of sleep by "sleeping in" on the weekends.Unfortunately,this causes irregular sleep and actually makes the problem worse. Most teenagers are not able to fall asleep until late at night.Since many teens aren't sleepy until around 11 pm.but need to be at school by 7:30 or 8:00 am .They cannot get enough sleep .During puberty ,the biological clock in the brain naturally re-sets to a later time ,and this causes teens to fall asleep later.Then ,when it's time to get up ,a teen's body clock is likely to still be producing the night-time hormones .This makes it hard for them to feel active and energetic in the morning. A growing body of research suggests that starting high school later improves attendance,achievements and grades.A few years ago in an important study ,test scores on the SAT college entrance exams in Edina,Minnesota jumped more than 100 points on average,when the morning school bell rang an hour later.Unfortunately,most schools are not set up to start later and fail to satisfy teen's sleep needs. Question: The text helps us to know more about teenagers' _ . Answer:
OPTIONS:
- daytime activities

Question: Read the following article and answer the question. Article: An American woman Anna Jervis was the first person to decide that mothers should have a holiday in their honor each year. Miss Jarvis started her campaign in 1906 in her home city Philadelphia. She wrote thousands of letters to congressmen ,city officials, teachers and newspaper publishers, proposing an official holiday for mothers. She traveled all over America, trying to get support for the idea. Her battle went on for years. In 1914 the Congress declared the second Sunday in May each year as Mother's Day. Anna Jarvis wanted Mother's Day to be a simple event. She thought children could honor their mothers by spending some time with them as an act of love and respect. However, the holiday turned out to be a major event for department stores, flower shops and greeting card industry, which Miss Jarvis didn't like. Americans spend millions of dollars on gifts for their mothers on this day. Younger children often try to prepare and serve breakfast for their mothers. Fathers may offer to take care of children so that mothers can enjoy themselves. The holiday becomes an important time for family fathering. Question: On Mother's Day, department stores, flower shops _ . Answer:
OPTIONS:
- are closed
- have fewer customers
- are full of people
- only have women customers
Answer: are full of people

Question: Read the following article and answer the question. Article: Who Owns the Moon? Within the next ten years, the U. S., China, Israel, and a crowd of private companies plan to set up camp on the moon. So if and when they plant a flag, does _ give them property rights? A NASA working group hosted a discussion this week to ask: Who owns the moon? The answer, of course, is no use. The Outer Space Treaty, the international signed by more than 100 countries, states that the moon and other celestial bodies are the province of all mankind. No doubt that would annoy all of the people throughout the ages, like monks from the Middle Ages, who have tried to claim the moon was theirs. But ownership is different from property rights. People who rent apartments, for example, don't own where they live, but they still hold rights. So with all of the upcoming missions to visit the moon and beyond, space industry thought leaders are seriously asking themselves how to deal with a potential land rush. " This is a very relevant discussion right now. We've got this wave of new lunar missions from around the world," said William Marshall, a scientist in the small-spacecraft office at NASA, but who spoke this week at an event hosted by NASA's Co Lab, a collaborative public-private working group. He was speaking from his personal interest and not on behalf of the agency. To be sure, the United States aims to send astronauts back to the moon by as early as 2015, in a mission that would include a long-term settlement. China and Israel, among others, are also working on lunar projects. And for the first time, several private groups are building spacecraft to land on the moon in an attempt to win millions of dollars in the Google Lunar X Prize. Some participants say that they plan to gain some property rights in the mission. Question: We can infer from the passage that _ . Answer:
OPTIONS:
- it's a waste of time to work on the lunar project
- " The Outer Space Treaty" forbids private groups to land on the moon
- all mankind has the right to land on the moon
- whenever you come to the moon, you'll get some property rights on it
Answer:
all mankind has the right to land on the moon
