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.

[Q]: Article: The United States covers a large part of the North American continent. Its neighbours are Canada to the north and Mexico to the south. Although the United States is a big country, it is not the largest in the world. In 1964, its population was over 185,000,000. When this land first became a nation, after winning its independence from England, it had thirteen states. Each of the states was represented on the American flag by a star. All these states were in the eastern part of the continent. As the nation grew toward the west, new states were added and new stars appeared on the flag. For a long time, there were 48 stars. In 1959, however, two more stars were added to the flag, representing the new states of Alaska and Hawaii. Indians were the first people of the land which is now the United States. There are still many thousands of Indians now living in all parts of the country. Sometimes it is said that the Indians are "the only real Americans". Most Americans come from all over the world. Those who came first in greatest numbers to make their homes on the eastern coast of North America were mostly from England. It is for that reason that the official language of the United States is English and that its culture and customs are more like those of England than those of any other country in the world.
Answer: Mexico is to the north of Canada.
[A]: Which of the following is TRUE according to the passage?

[Q]: Article: An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry's success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.
Answer: To arouse the American public's interest.
[A]: Why may Justin Bieber be sent into suborbital space?

[Q]: Article: Encouragement and praise can come in many forms, and some ways are better for child development than others. Researchers at the University of Chicago who studied mother-child interactions found that the type of praise children receive affects their attitudes towards challenges later in life. Specifically, praise that focused on their behavior and the choices that kids made helped them deal with difficult experiences better five years later, compared with praise that focused more on the child himself, like "You're a good boy." The study, which appears in the journal Child Development, is the first major study of praise and child development done outside of a lab setting. "It's exciting to see _ play out in the real world," said Elizabeth Gunderson who led the study. "Praising the efforts, actions and work of kids is going to be more beneficial in their long-term persistence and desire to be challenged and work hard in the future." Such "process praise" includes comments such as "You worked really hard", which emphasize a child's actions. "Person praise" includes comments like "You're so smart", which focus on a child's personal qualities. These distinctions aren't new in the field of psychology, but exactly how they affect children's development over the years hasn't always been clear. As part of the study, the researchers visited the homes of more than 50 kids between the ages of 1 and 3, and filmed their daily interactions with their parents during 90-minute sessions. Five years later, the researchers followed up with the families, measuring the children's attitudes towards challenges and problem solving. The children who grew up with more process praise were more open to challenges. Though person praise didn't seem to have any negative effect on the children, the study suggests that process praise teaches children that their talents and abilities can be developed and improved, while person praise sends the message that their abilities are fixed and therefore not easily changed.
