Article: More than 700 business leaders, government officials and investors gathered in Mountain View, California in December,2012 to attend the Social Innovation Summit. It is an invitation-only conference aimed at finding new ways to deal with old problems. Traffic jam is a problem that Bruggemann hopes to solve."Traffic is really bad in most countries and we thought there must be some way of doing something about it."Last week, his team, winning the prize for its"nunav"traffic management system, received a Microsoft Imagine Cup Grant of $100,000."Everyone that's using our system sends his present position as well as the destination to our servers every 30 seconds. And with that information our central system can reroute all of the cars in a way that everyone gets his individual best possible route." Bruggemann says early research with the system has been promising."We found out that it could be possible to save up to 20 percent of the fuel consumption. Even more interesting, it can save up to 50 percent of the time you spend in traffic so you could get to your destination twice as fast." Team Cypher256 from Uganda also was invited to the Social Innovation Summit. They developed a device ,called WinSenga, aimed at improving health care for pregnant women in Africa. It measures the early baby's heart sounds to help test the heart rate, age and position of the baby in the mother. The device is similar in operation to an ultrasound test, but is far less costly and very practical in Africa. This is the third year for the Social Innovation Summit. The event is held twice a year, once in New York and once in California. The first one in 2012 was held in May. The United Nations'Office for Partnerships helped to organize the event. Question: The device WinSenga is intended to _ . - improve the health care for pregnant women - promote the heart rate of pregnant women - measure the size of the early babies - help the operation on women
improve the health care for pregnant women

(Question)
Read the following article and select the best answer. Article: Baekeland and Hartmann report that the " short sleepers" had been more or less average in their sleep needs until the men were in their teens. But at about age 15 0r so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to regard their nightly periods of unconsciousness as bothersome interruptions in their daily routines. In general, these "short sleepers" appeared ambitious, active, energetic and cheerful. They stuck to their opinions, and were very sure about their job choices..They often held several jobs at once, or worked full-or part-time while going to school. And many of them had a strong urge to appear "normal" or " acceptable" to their friends and colleagues. When asked to remember their dreams, the " short sleepers" did poorly. More than this, they seemed to prefer not remembering. Similarly, their usual way of dealing with psychological problems was not to admit that the problem existed, and then to keep busy in the hope that the trouble would go away. The sleep patterns of the " short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic . The "long sleepers" were quite different indeed. Baekeland and Hanmann report that these young men have been lengthy sleepers since childhood. They seemed to enjoy their sleep, protected it, and were quite concemed when sometimes they didn't have their desired 9 hours of nightly bed rest. They tended to remember their dreams much better than the " short sleepers". Many of the "long sleepers" were shy, anxious, quiet, nervous, passive, mildly depressed, and unsure of themselves ( particularly in social situations) . Several openly stated that sleep was an escape from their daily problems. Question: It can be learned from the passage that the"short sleepers" _ . - do not know how to relax properly - are more unlikely to run into mental problems - are full of energy even under the pressures of life - often pay little attention to the consequences of inadequate sleep
(Answer)

The interesting part is how builders managed to create this genius idea, but the house is a fact and everyone admires their creativity!
