Article: WASHINGTON -- It is announced Friday that White House visitor records will be opened up on a regular basis for the first time in modern history, providing the public an unusually detailed look at who gets the opportunity to help shape American policy at the highest levels. "Americans have a right to know whose voices are being heard in the policymaking process," the president said in a written statement issued by the White House while he vacationed with his family at Camp David. By the end of the year, the White House will begin posting online every month the names of the people who visited in the last 90 to 120 days. Each person's full name will be listed, along with the date and time they entered and left and the name of the person they visited. About 70,000 to 100,000 people visit the White House each month, and the records will include tourists as well as people conducting business. The White House pointed out several exceptions to the policy: "purely personal guests" of the Obama family; those cases in which the disclosure of visitors' names "would threaten national safety interests"; and those who come for "particularly sensitive meetings," like candidates for a Supreme Court nomination . Officials said only a "small number" will fit in the latter category , and their names would eventually be disclosed after they are no longer secret, like after a nomination is publicly announced. Moreover, they said, the number of undisclosed visitors will be disclosed, to make clear how few they are. Question: From the passage we can learn that _ . - All the visitors' names will be posted online soon after their visits - Not all visitors are allowed to visit the White House - Some visitors' names can be found online until they're not secret - The records of the visitors will be kept for at least 4 months
(A).
Some visitors' names can be found online until they're not secret

Read the following article and select the best answer. Article: In some parts of the United States, farming is easy. But farming has always been difficult in the northeastern corner of the country, which is called New England. New England has many trees and thin, rocky soil. Anyone who has wanted to start a new farm there has had to work very hard. The first job has been cutting down trees. The next job has been digging the stumps of the trees out of the soil. Then the farmer has had the difficult job of removing stones from his land. This work of removing stones never really ends, because every winter more stones appear. They come up through the thin soil from the rocks below. Farmers have to keep removing stones from the fields. Even today, farms which have been worked on for 200 years keep producing more stones. That is why stone walls are used instead of fences around New England fields. The stone walls are not high; a man can easily climb over them. But they keep the farmer's cows from joining his neighbor's cows. Question: According to this selection farming is difficult in New England because _ . - the winter is very long there - the farms are very old - the soil is rocky and thin - the summer is too hot
(A).
the soil is rocky and thin

Read the following article and select the best answer. Article: Many children have a "bug period"--a time of life when bugs are a source of endless fascination and learning. Naturalist Edward O. Wilson jokes that unlike other kids, he never grew out of his bug period. Luckily for this biologist, his lifelong passion for ants has led to a career rich in accomplishments and praise. He is not just the world's foremost expert on the social behavior of ants, but also the receiver of the National Medal of Science and two Pulitzer Prizes for nonfiction. Now, at the age of 80, Wilson has tried his hand at fiction. His first novel, Anthill, combines two of his greatest loves -- his childhood home, Alabama, and the ants that have been his lifelong friends. Described as a "six-legged Iliad," Wilson's Anthill draws parallels between human and ant societies. Though there are no ant bands, secret police, or schools of philosophy, both ants and man conduct wars, divide themselves into specialized classes of workers, build cities, maintain infant nurseries and cemeteries, take slaves and practice agriculture, though ant societies are more energetic, selfless, and efficient than human ones. The book's first and third sections deal with the adventures of an Alabama boy, Raphael Semmes Cody, who goes by the name Raff. The boy grows up knocking around the Nokobee woods; he's drawn to its natural wonders, and uses the forest to escape from his parents' unhappy marriage. In the woods he leaves almost no stone unturned as he discovers the forest's rich flora and fauna . Raff grows up and heads to Harvard to study law, but returns later in life to protect the Nokobee from crazy developers. But fans of Wilson's science will be most interested in the book's middle section, where the author inserts a mini-novel describing the trials and sufferings of the ants living in the endangered forest. Reviews of the book have been mixed. Writing for The New York Review of Books, Margaret Atwood praised Wilson for his first novel, saying that it is highlighted by a diversity of ideas and an imaginative... Question: What can we learn from Edward O. Wilson's joke? - He is unwilling to leave his childhood behind. - He is an excellent naturalist with a good reputation. - He has had a lifelong passion for insects. - He has the same hobbies as many children.
