In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Article: NOT all math skills are learned in the classroom. Some of them come naturally. Consider the split-second calculations you make when you estimate the number of empty seats on the school bus or the number of cookies in a cookie jar. These estimates can often be done without counting. That's because humans are born with the ability to closely guess the number of items in a group. Researchers call this ability a person's "number sense". To see how a person's inborn number sense might be linked to mathematical performance in the classroom, psychologist Justin Halberda and his colleagues from Johns Hopkins University in prefix = st1 /Baltimore,USran some tests. The scientists asked 64 14-year-olds to look at images of yellow and blue dots that flashed on a computer screen for a fraction of a second. Each image contained between 10 and 32 dots that varied in size. Some images contained twice as many blue dots as yellow dots. In other images, however, the number of blue and yellow dots was nearly equal. For each image, the students were asked to estimate which color1 had more dots. The scientists found a wide variation in how well students could pick the color1 with the most dots. The scientists then looked at the students' math scores dating back to kindergarten. Children that performed best in the image test also scored the highest in standard math tests. The same finding held true at the other end of the spectrum . Students who didn't score well on the image test received lower math scores. The study was the first to show a link between a person's inborn number sense and his or her achievement in formal math training. Does this connection mean that one cannot be good in math if they have a weak number sense? Or that having a strong number sense is a guarantee for good grades in math? The answers are not clear. While scientists continue looking at the possible links between a person's number sense and math achievement, one thing is certain: Doing lots of math homework will _ your chances of success.
Answer: Those who have a strong number sense are sure to do well in math.
Which of the following is not true according to the passage?

Article: The tourism business in Hong Kong has been through some very hard times. Ten years ago, with all the economic problems in Asia, far fewer tourists were visiting Hong Kong. However, the SAR was still one of the most popular destinations in Asia, and a favored location for international meetings and exhibitions. The year 1997 was the best year for tourism in the 1990s. However in 1998, the figure was down by 8% from 10.4 million tourist arrivals recorded in the previous year. Tourism was still big business, though. The mainland was Hong Kong's largest source of visitors, making up over a quarter of all arrivals. Travelers from Taiwan Province, South and Southeast Asia and Japan made up the most of other visitors. Tourism remained a major source of foreign exchange, although tourists spending dropped. Tourists often made short visits, staying an average of three to four days. Most tourists came to Hong Kong for business or leisure , or a mixture of both. Shopping was still the favorite thing of tourist activity and spending. The average visitor spent about HK$ 3,000 - not including accommodation and food. Hong Kong Tourist Association officials developed various plans to develop interest in Hong Kong as a tourist destination, and they hoped these policies would work.
Answer: Fewer tourists were visiting Hong Kong than before.
What situation was Hong Kong facing in the passage?

Article: You might not want a holiday in your hometown, but there is probably someone who does. And, in exchange, you could have a cheap vacation anywhere in the world. Just picture the scene: you're watching the sunset from the balcony of a Caribbean island house. It's large. And it's free as long as you don't mind the owners living in your home at the same time. All you need to be a home-swapper is the Internet and a rough idea of when and where you want to go on holiday. When you find someone whose dates match yours, and who wants to visit your area, you're all set to swap. The advantages are numerous: you can save a fortune in accommodation cost. You could get to use the owners' car, boat, bikes, pool or gym. You might even be able to come to an arrangement about looking after each other's pets! You also get to live like a local, and you might be invited around to neighbors' homes for tea, barbecues and tips on the area. People say that these cultural experiences are the memories that last. Plus, instead of one tiny hotel room, you have an entire house where you can make yourself at home. And it's not cold and impersonal like a hotel room. Of course, there are disadvantages. A lot of effort and communication are needed before the arrangements are finalized. Nobody wants a stranger living in their house, sleeping in their bed and using their bathroom, so you have to get to know each other well beforehand. Some people are concerned about theft or property damage, but in reality this is very rare. Most home-exchangers have the view that "If they can trust me with their house, I can trust them with mine." The worse complaint people have is the difference in standards of cleanness. If you're interested in home-exchange for your next holiday, start by contacting a famous agency like homelink.org and intervac,co.uk. These agencies will also have advice about preparing for a home-exchange.
Answer: A gathering in his neighborhood.
What will you most probably remember if you have exchanged your home with another?
