[EX Q]: Article: A new report says only about half of all students in the main school systems of America's largest cities finish high school. The report notes higher rates of graduation -- over 70% --in areas surrounding the cities. Researchers studied high school graduation rates from the 2003, 2004 school year. They also identified the nation's fifty largest cities. The largest, New York City, had a population of more than eight million. The smallest city was Wichita, Kansas. It had about three hundred and sixty thousand people. Researchers used a system of measurement called the cumulative promotion index to find graduation rates. School officials in many of the cities studied said the resulting numbers were too low. That is because different areas use different methods to find graduation rates. Critics say many methods do not give a true _ of the number of students who leave high school before finishing. Other studies have put the national graduation rate at about 70%. But experts agree that too many students are not completing high school. They estimate the number at more than one million each year. The report was prepared for America's Promise Alliance. The private group aims to help children receive services they need to succeed. General Colin Powell was chairman of America's Promise Alliance when it was formed in 1997. He attended the press conference Tuesday where the report was released. He said studies have shown that the US must do more to educate the leaders and work force of the future. Secretary of Education Margaret Spellings also spoke. She said the government will propose that states use the same methods when reporting graduation rates. Alliance officials also announced the start of a nationwide campaign to improve graduation rates. It is to include a series of meetings to be held in every state over the next two years. The meetings will bring together elected leaders, business owners, students, parents and education officials. They will develop plans to increase the number of Americans who finish high school.

[EX Q]: Article: Ever tried taking smart drugs to perform better in exams? They certainly work. Before last summer's exam, a few of my mates, merely out of curiosity, took a considerable amount of Modafinil, a drug normally used for narcolepsy . Guess what? While I was feeling sleepy, bored by revision, my mates were more focused. Modafinil is a smart drug that gives a user a feeling of staying awake for hours. It also sharpens the mind, improves memory and helps problem-solving. But it does more than just keeping you awake. It disturbs your mental system, making you desperate to do what you are doing. You just don't want to do anything else but revise all the time non-stop. A recent study discovers that healthy people use smart drugs, like Modafinil, to get down to and complete tasks they have been putting off, because these tasks seem more enjoyable when taking these drugs. This might sound like what a stressed student desires. However, the pills have a range of side-effects. "At present no evidence shows that these drugs are safe in healthy people," as a medical expert puts it, "Ordering online, though easy, is a dangerous way to obtain drugs. You never know what you're actually purchasing. " In my experience, Modafinil changes people's behaviour too. Over those weeks my friends became different people--in turn aggressive, cold. Even eating became "a waste of time" and so did conversation. A BBC survey found that of those who had tried smart drugs before, 92% would do so again. My friends say they'd happily do so without considering the practice a form of cheating. I admit I was curious--but not enough to try it. Seeing the strange behaviour of other users, I feel a little bit upset and scary. Modafinil may promise to change your grades, but it might also change the way you act. Don't say you haven't been warned!
Question: According to the author, his mates took Modafinil for the purpose of _ .
Options: (A) escaping from reality (B) getting better exam results (C) curing their narcolepsy (D) leading an active life

[EX Q]: Article: There are plenty of different parks to visit in the UK. All theme parks in Britain have cafes, restaurants, picnic areas and gift shops, so you'll still have plenty to see and do when you and the kids have been on enough rides. There are usually smaller "funfair" rides and games as well, so younger children won't get bored. Several theme parks also have other attractions next to them, e.g. water parks often open all year round, unlike the theme parks. Wherever you are in Britain, there's likely to be a theme park within one or two hours' drive, bus ride or train journey. Several theme parks even have accommodation so you can stay for a day or two if you want to make a trip into a short holiday. Prices for UK theme parks vary considerably; some have an entrance price which allows you to go on all the rides, while in others you have to pay for every ride individually. It can also make a difference whether you go during peak time or not. For example, tickets always cost more during school holidays and weekends than they do during the weekdays. Theme parks always get very busy during the summer months, so if you don't like crowds, it's usually a good idea to go earlier or later in the year! If you're thinking of visiting a UK theme park, it's worth having a look for special offers on tickets. Products such as chocolate bars and cereals sometimes have "buy one get one free" offers on theme park tickets, so keep a look out in shops and supermarkets.
Question: This passage mainly talks about all the following EXCEPT _ .
Options: (A) things to do (B) prices for theme parks (C) rules to obey (D) special offers
