Read the following article and select the best answer. Article: CHICAGO (AP) On Jan. l,an order went into effect requiring that every checked bag at more than 400 of the nation's commercial airports be screened for bombs and weapons. Sunday was expected to the heaviest travel day since Jan. l. Yet spot checks on Sunday at several of the nation's airports showed no major delays caused by the new security measures. At the international terminal for Northwest Airlines at John F. Kennedy International Airport inprefix = st1 /New York, passengers waited up to 30 minutes longer than usual. Their bags were sent through giant screening machines and workers tore open taped boxes and searched through their contents before closing them up again. Most travelers simply accepted stricter screening developed since the terrorist attacks on Sept. 11,2001,before which only 5 percent of the roughly 2 million bags checked each day were screened for bombs. The U. S. government has put an additional 23,000 people into airports to carry out the new order. Sonny Salgatar, a 23-year-old college student flying home to San Diego fromChicago, was told by an airport officer after the first pass that one of his bags was "hot", meaning there was something he couldn't identify and he wanted to open the bag for an inspection. The "hot" item turned out to be Salgatar's clothing iron. "Listen, anything they want to do for security is OK for me," Salgatar said. But not all of the passengers hold the same viewpoint as Salgatar's, complaining that they had to arrive at the airport too much time ahead of their schedule. Question: The best title of the passage might be - . Fear of Terrorist Attacks - Latest Screening Technology - . New Security Measures Adopted - Inspection of Bombs and Weapons

Read the following article and select the best answer. Article: Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing .Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others. Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma , Jane Bums at the Harvard School of Public Health found. Based on these findings.Bums said that current recommended dose of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs.Teens who eat less fruit and don't take in enough fatty acids are more likely to have asthma and the signs of breathing difficulty. Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers.Fatty acids are also found in some nuts as well as some green vegetables'.Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm . More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks."I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said. Burns added that there are several different ways to get the necessary nutrients."I think vitamin supplements are fine.I think adding vitamin D to orange juice is fine.But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said.The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings. Question: What is the best title for the passage? - Poor nutrition hurts teens' health. - Teens lack proper nutrition. - Teens are easy to suffer from diseases. - More fruit help keep teens healthy.
Poor nutrition hurts teens' health.

Question: Read the following article and select the best answer. Article: People with less education suffer fewer stressful days,according to a report in the current issue of the Journal of Health and Social Behavior. However,the study also found that when lesseducated people did suffer stress it was more severe and had a larger impact on their health. From this researchers have concluded that the daytoday factors that cause stress are not random .Where you are in society determines the kinds of problems that you have each day,and how well you will deal with them. The research team interviewed a national sample of 1,031 adults daily for eight days about their stress level and health.People without a high school diploma reported stress on 30 percent of the study days,people with a high school degree reported stress 38 percent of the time,and people with college degrees reported stress 44 percent of the time. "Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health."lead researcher Dr.Joseph Grzywacz,of Wake Forest University Medical Center,said in a prepared statement."The downward turns in heBaptistalth were connected with daily stressors and the effect of daily stressors on their health is much more devastating for the less advantaged." Grzywacz suggested followup research to determine why lesseducated people report fewer days of stress when it is known that their stress is more acute(severe)and chronic (lasting). "If something happens every day,maybe it's not seen as a stressor"Grzywacz says."Maybe it is just life." Question: Which group reported the biggest number of stressful days? - People without any education. - People without high school degrees. - People with high school degrees. - People with college degrees.
Answer: People with college degrees.
