PROBLEM: Article: The round-the-clock availability that cell phones have brought to people's lives may be _ amily life, a new study suggests. The study, which followed more than 1300 adults over 2 years, found that those who consistently used a mobile phone through out the study period were more likely to report negative "spillover" between work and home life--and, in turn, less satisfaction with their family life. Spillover(,) actually means that the line between work and home began to become unclear. Work life may invade home life--when a parent is taking job-related calls at home, for instance--or family issues may start to take up work time. For example, a child may call Mom at work, telling her "the microwave exploded", explained Noelle Chesley, an assistant professor of society at the University of Wisconsin Milwaukee and the author of the study. The problem with cell phones seems to be they are allowing for ever more spillover between work and home. This may be especially true for working women, the study found. Among men, consistent use of mobile phones seemed not to allow more work issues to creep into family time. But for women, the spillover tended to go in both directions--being "connected" means that work cuts into home time, and family issues come into work life. Cell phones seem to be opening more lines for stressful exchange among family members. But there may be ways to control the spillover, according to Chesley. Employers, she said, should look at their policies on contacting employees after working hours to make sure their expectations are "reasonable". For their part, employees can decide that cell phones go off during family time, Chesley said.
Question: What is the main idea of this passage?
Options: (A) Cell phones offer 24-hour availability. (B) Cell phones get life and work mixed. (C) Women don't use cell phones in an effective way. (D) Men are better at dealing with family problems.

SOLUTION: B

PROBLEM: Article: Kids at the Interlake School Division were the first Canadian students to take part in a program to send experiments to the International Space Station.(ISS). Jordan Schott and three other sixth grade students came up with the idea to test royal jelly in space . Their experiment came very close to be tested on the space station. "We were seeing if we could send it to space, and if it would lose its nutritional value" faster and or slower, "said Schott. Schott is one of the 18 students in the Space Knights Club at Woodlands Elementary School, part of the Interlake School Division. Over 450 students from the Division took part in the program. "I thought we were just students and we couldn't do much in the way of that. It's a way to communicate with people up there ," said Braeden Clark, a seventh grade student who is also in the club. The astronauts shared what they learned with their school with a full day of activities all about science and space. Teacher Maria Nickel is the organizer of the club. She said the day was great for students to learn what they could do. "Space is one of those great things that get kids excited, but it also gives them the chance to do so much. They can be an astronaut; they can be an engineer, "She said. The day was held in honour of Chris Hadfield, a Canadian astronaut now in the Internal Space Station. "It gives kids someone more to look up to. Here's a real hero to look up to who's doing it all, doing it through education," said Nickel. Jordan Schott thinks it's really cool. "To me it seems so cool how people can go up to space, and science is something I've always liked," She said. Schott says she wants to follow in the footsteps of Hadfield and be an astronaut when she gets older. One of the winning experiments in the competition was produced by students from Argyle, Manitoba. It will travel to the space station in the fall of 2013.

Options: (A) was carried out by 18 students. (B) was to test royal jelly in space (C) was designed to send experiments to the ISS (D) allowed the first students to connect with the ISS

SOLUTION: C

PROBLEM: Article: Chimpanzees, long considered reluctant to share, apparently can display selfless tendencies, revealing one more key way our closest living relatives are like humans, scientists find. These findings could shed light on the evolution of _ in humans. Previously, a belief was widely held that human altruism evolved only after humans split from their ape cousins about 6 million years ago. In recent years, however, research has revealed just how much chimpanzees have in common with us. They can hunt with spears, play with dolls and mourn their partners' death. "Most of the earlier studies had presented the apes with a complex implement that helped them deliver food to themselves or others, often so complicated that the experiments tested tool skills rather than social tendencies," De Waal told Live Science. "Ours is the first study that uses no such implement at all." In addition to using complex food-delivery systems, past experiments often placed the chimpanzees so far apart that they might not have realized how their actions benefited others. In these new, simplified experiments, two apes were housed next to each other with a screen through which they could see each other. Then, one chimpanzee had to choose between two differently colored tokens from a bin, one of which represented a pro-social option, the other a selfish option. The pro-social option would cause both chimpanzees to receive a piece of banana wrapped in paper. The selfish option only rewarded the ape who made the choice. In a study with seven adult female chimps placed into various pairs, the scientists found all the apes showed a definite preference for the pro-social option. "For me, the most important finding is that like us, chimpanzees take into account the needs and wishes of others," researcher Victoria Horner, said. The chimpanzees behaved especially altruistically toward partners who either patiently waited or gently reminded them that they were there by drawing attention to themselves. They were less likely to reward partners who pressured through making a fuss, begging persistently or spitting water at them. This is opposite to a long-standing view that the chimpanzees only share food under pressure.
Question: Recent researches are performed with less complicated implements mainly to _ .
Options: (A) show that chimps are only good at using implements (B) see whether chimps are willing to share food with others (C) find out if chimps are likely to reward partners (D) test chimps' social tendencies instead of tool skills

D
