Read the following article and select the best answer. Article: Over thousands of years, human beings have been learning about more and more about this world, and have figured out many ways to avoid risks and make our lives easier. Even in ancient times, we used fire to frighten away animals, built simple boats to cross waters, and armed ourselves with sharpening stones and sticks. Nowadays, with advanced technology and instrument, people know the world better than ever. It's surprising how much people already know about this world and how much we've changed our lives by using the knowledge we have. But if you think we know everything, that's wrong. I guess sometimes we have to accept the limitation on our understanding of the world. No matter how much we're already known about the world, there are things that remain mysterious. I learned this from my pregnancy which ended in the 6th month, due to a placental abruption . I started to see my OB/GYN every month, taking vitamins regularly, doing all the lab tests to make sure we were expecting a healthy baby. All the results looked promising, and we thought we would have a healthy baby girl in January next year. Even in the week before placental abruption, when I was in hospital because of a sudden bleeding, doctors didn't believe there were any bad possibilities after reading my blood tests. Unfortunately it still happened. Later, I asked my doctor "So what caused this?" She said, "I don't know. We probably will never know." After leaving the hospital, I sometimes do feel frustrated for what happened. But I already accept the fact that there are simply things that we do not know. No matter how well you plan and monitor your life there are uncertainties that can not be predicted and thus can not be avoided. _ Her name was Janet. She came to the world in April, and left us 6 months later. Though we never had the chance of meeting her, she is always our beloved daughter. In the late May 2013, during our first OB visit, we saw a little heart beating happily inside its mother. We couldn't even tell that was a baby, but we... Question: What happened to the baby girl? - She died six months after birth - She died in a medical accident. - She died before she was born - She died from lack of equipment.
She died before she was born

Read the following article and select the best answer. Article: On countless mornings over the past year, I stood with my son, James, in our driveway, watching our neighbor hurry off to kindergarten.My wife and I wanted to give James the best education, but that meant we'd have to change our jobs and spend less time with our kid.I asked myself, "Would this trade-off be worth it?" When I look at the research on child development, I think it might not.Where our kids go to school might matter less than most American parents think. Social scientists have long tried to determine why some children grow up to be successful.In a 2001 study, Greg Duncan, a professor of education at the University of California, measured the influence that the people in a child's life have on how well the child does in school.Duncan and his team found almost no relationship between how students did on the test and whom they sat beside in class, whom they hung out with after school and who lived in their block.The only meaningful link they found was between siblings and twins in particular. For a long time, scholars thought that a family's income heavily affected how well kids did in life.But that might not be the case.When Susan Mayer at the University of Chicago looked at the relationship between family income and lifetime achievement, she ran a series of experiments to measure it, finding such outcomes weren't caused by income.She argued that the things that make a difference are relatively inexpensive: the number of books a kid has or how often his family goes to museums. Lareau, another scholar began one of the most in-depth observations of American parenting.He concluded that success is much more related to the amount of time parents spend with their children.He said "Many parents I interviewed are anxious about their children's futures.But they have exaggerated the sense of the risks involved if they don't give their children 'the best' of everything." So at last, we decided to leave things as it were.More time with our kid is the best we can provide. Question: From the passage we know that most American parents _ . - spend a lot of time with their children - like to buy a variety of books for their children - think children's achievement largely depends on schools - believe their income cannot afford children's education
think children's achievement largely depends on schools

Read the following article and select the best answer. Article: The Attack on September 11th New York: When the first jet struck Tower 1 at World Trade Center at 8: 48 am on Tuesday, the people in Tower 2 at World Trade Center with a view of the instant damage across the divide had the clearest sense of what they too must do : get out fast. Katherine Ilachinski, who had been knocked off her chair by the blast of heat exploding from the neighboring tower, was one of those. Despite her 70 years of age, Ms Ilachinski, an architect working on the 91st floor of Tower 2 at World Trade Center, the south tower, went for the stairs. Twelve floors above her, Judy Wein, a manager, screamed and set off too. But others up and down the 110 floors, many without clear views of the damage across the way and thus unclear about what was happening, were not so sure. And the 18 minutes before the next plane would hit were ticking off. Among the uncertainty about what was the best thing to do, formal announcements inside the south tower instructed people to _ , assuring them that the building was sound and the threat was limited to the other tower. Some left, others stayed, some began to climb down and, when met with more announcements and other warning to stop or return, went back up. The decisions made in those instants proved to be of great importance, because many who chose to stay, were doomed when the second jet crashed into the south tower killing many and stranding (...) many more in the floors above where the jet hit. One of those caught in indecision was the manager at Fuji Bank USA. Richard Jacobs of Fuji Bank left the 79th floor with the other office workers, but on the 48th floor they heard the announcement that the situation was under control. Several got in the lifts and went back up two minutes or so before the plane crashed into their floor. Question: Few people would have died if _ - more announcements had been made - people hadn't used the lifts - the incident had happened on a weekend - people chose to stay
(Answer)
the incident had happened on a weekend
