Q: Read the following article and answer the question. Article: My 11-year-old son and I rides bikes to and from his school every day. I accompany him on the 20-minute ride through Manhattan, drop him off and return at the end of day to pick him up. We always ride together; sometimes he leads; sometimes I do. And as we ride, we communicate the ways to minimize   the dangers: Don't go too fast, and watch out for doors suddenly swinging out from parked cars and jaywalking pedestrians, etc. Some friends worry about the risk of riding in traffic, but is there a better way to let my son know how to deal with traffic dangers? But recently he requested me to start hanging back a half block or so. This way he could enjoy the feeling of riding on his own, with the security of knowing that I was nearby in case he needed me. This is healthy, of course, as my son needs space to develop independence in preparation for his inevitable (,) departure from home. However, that means soon he will want to ride to school on his own, and I will no longer have this wonderful routine. "Let your children go if you want to keep them." I understand this and am trying to let my son go in age-appropriate phases, but I still suffer. It's one of the most troubling experiences of parenthood -- recognizing that your presence is becoming less welcome. My dilemma as a husband mirrors the concern I feel as a parent. My wife has just left on a six-month mission to cover the situation in Libya. In the days leading up to her departure, we spoke openly about the possibility, however unlikely, that she might be killed. But while I influence her decisions, I do not control them. Finally, it was her decision. I know that letting go is the wisest path in this case too. As we travel through life's phases, we must let go of so much. And I don't think it gets easier with practice. But maybe just accepting that eventually we will have to let go is the secret to living a full life. Question: What would be the best title for the passage? Answer:
Answer: Letting go.

Q: Read the following article and answer the question. Article: The creation of a Chinese Green Card in 2004 was a milestone in the country's immigration law. Five years on, the card is an increasingly sought-after document. On August 15, 2004, the Regulations on Examination and Approval of Permanent Residence oAliens in China created a Green Card system granting qualified foreigners the right to live in China permanently. Liu Lili, who works in the Exit and Entry Administration of Beijing Municipal Public Security Bureau, has watched the Green Card system develop since its inception. She said nearly all applications received by the Bureau are approved. So far, 323 people have been granted a "Green Card" qualifying them for permanent residence in Beijing. Another 15 are awaiting final approval. It takes around 6 months to process each application. Of the 323 Green Card holders, 94 are wives or husbands of Chinese citizens; 50 are minors dependent on their parents; 20 are senior citizens returning to live with relatives; 114 are individuals who have made outstanding contributions or are of special importance to China (another 7 are their family members); and 23 are high-level foreign personnel who hold posts in businesses (another 15 are their family members). Liu said the authorities had been granting residence to returning senior citizens for some time before the Green Card system was formally launched .The government has approved permanent residence for over 3,000 foreigners since the implementation of the Law on Control of the Entry and Exit of Aliens which was adopted by the Standing Committee of the National People's Congress in November 1985. Four groups of people are eligible for permanent residence: high-level foreign personnel who hold posts in businesses that promote China's economic, scientific and technological development or social progress; foreign citizens who make large  direct investments in China; persons who have made outstanding contributions or are of special importance to China; and people who come to China to be with family, such as husbands and...

Q: Read the following article and answer the question. Article: Thousands of dead red-winged blackbirds fell from the sky in an Arkansas town on New Year's Eve after massive injuries, tests by Arkansas officials concluded on Monday. Some 5,000 birds mysteriously fell from the sky in Beebe, Arkansas after dark on New Year's Eve. "The birds suffered from acute physical injuries leading to internal hemorrhage  and death. There was no sign of infectious disease," the Arkansas Game and Fish Commission said in a statement. The birds were otherwise healthy, it said. One theory is that birds were frightened by New Year's fireworks and flew into buildings or other objects. "Loud noises were reported shortly before the birds began to fall from the sky," the statement said, adding that blackbirds have poor night vision and seldom fly at night. Another theory was that severe weather such as lightning accounted for the loud noises but this was  _ because the violent weather had already left the area. "We're leaning more toward a stress event," said Arkansas Game and Fish Commission spokesman Keith Stephens. The commission also is trying to determine what caused the deaths of up to 100,000 fish over a 20-mile stretch of the Arkansas River near a dam in Ozark, 125 miles west of Beebe. The fish were discovered on December 30. Stephens said the commission expected results on the fish tests in probably a month. Since almost all the fish were one species -- bottom-feeding drum, Stephens said, the test was very important. Stephens also said: "The events do not appear related." Both that section of the river and the air at the site of the bird deaths were tested for toxins . Beebe is a town of about 4,500 people located 30 miles northeast of the state capital. Question: According to Stephens, we can infer the probable cause of the dead fish is   _  . Answer:
Answer:
