Read the following article and select the best answer. Article: "One thing I enjoy about my job is that I can work on something that is actually active," says Game McGimsey, an American volcanologist . Part of his job includes keeping an eye on Alaska's many active volcanoes and giving people a heads-up when a volcano might erupt . Like most jobs in the science, volcanology requires a lot of education. McGimsey received an undergraduate degree in geology at the University of North Carolina, then landed an internship with a geologist at the USGS whose work field was about volcanoes. After earning a graduate degree at the University of Colorado, McGimsey accepted a job with the USGS and has been with the Alaska Volcano Observatory for 25 years. Volcanoes can influence the world in ways we might not think about. For example, on Dec.15 1989, a 747 jetliner (a large airplane) flew through a thick ash cloud produced by Mount Redoubt, an Alaskan volcano that hadn't erupted in 25 years. The ash caused all four engines to die, and the plane's electronics went dead. "The plane was within several thousand feet of flying into the mountains below when the pilots got a couple of engines restarted and landed safely in Anchorage," McGimsey says. It cost nearly $80 million to repair the damage to the plane. Such situations show just how dangerous volcanoes can be. However, volcanologists know the risks and are prepared to protect themselves. McGimsey admits, "There is certainly a higher danger level in volcanology than some other jobs. We understand how serious the danger is, and we don't like taking unnecessary chances. We avoid getting too close to an erupting volcano, because it is not worth injury or death simply to get a rock or a photograph." Question: Before working for the USGS, McGimsey _ . - had been a pilot for 25 years - knew nothing about the organization - had taught at the University of North Colorado - had studied at the University of Colorado
**Answer**
had studied at the University of Colorado

Read the following article and select the best answer. Article: The baby monkey is much more developed at brith than the human baby. Almost from the moment it is born,the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large,warm, and soft object in its environment , particularly if that object also gives it milk. After a week or so , however, the baby monkey begins to avoid newcomers and focuses its attentions on "mother"-----the real mother or the mother-substitute . During the first two weeks of its life warmth is perhaps the most important psychological thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother-substitutes ----one covered with cloth and one make of bare wire. IF the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after brith the baby monkeys picked the warm wire mother-substitutes as their favorites. Thereafter they switched and spent most of their time on the more comfortable cloth mother. Why is cloth preferable to bare wire? Sometime that the Harlows called contact comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers' skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire does n't "rub"as well as does soft cloth. Prolonged "contact comfort" with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk. According to the Harlows, the basic quality of a baby's love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no... Question: It can be inferred that when the baby monkey feels secure, _ . - it frequently rushes back for a deep embrace when exploring the toys - it spend more time screaming to get rewards - it is less attracted to the toys though they are interesting - it cares less about whether its mother is still around
**Answer**
it cares less about whether its mother is still around

Read the following article and select the best answer. Article: WASHINGTON - Barack Obama swept to victory as the first black president in the US history Tuesday night in an electoral college landslide that overcame racial barriers as old as America itself. "Change has come," he told a huge group of cheering supporters. In his first speech as victor, Obama catalogued the challenges ahead. "The greatest of a lifetime," he said, "two wars, a planet in danger, the worst financial crisis in a century." He added, "There are many who won't agree with every decision or policy I make as president, and we know that government can't solve every problem. But I will always be honest with you about the challenges we face." The son of a black father from Kenya and a white mother from Kansas, the Democratic senator from Illinois sealed his historic triumph by defeating Republican Sen. John McCain in a string of wins in hard-fought battleground states -- Ohio, Florida, Virginia, Iowa and more. In his speech, Obama invoked the words of Lincoln and echoed John F. Kennedy. "So let us summon a new spirit of patriotism, of service and responsibility where each of us resolves to pitch in and work harder," he said. He and his running mate, Joseph Biden of Delaware, will take their oaths of office as president and vice president on Jan. 20, 2009. Obama will move into the Oval Office as leader of a country that is almost certainly in recession , and fighting two long wars, one in Iraq, the other in Afghanistan. Obama has said his first order of presidential business will be to tackle the economy. He has also pledged to withdraw most US combat troops from Iraq within 16 months. Question: According to the passage, Obama's attitude toward the challenges he faces is _ . - positive - negative - ambiguous - worried
