The New York Times' Christine Negroni reports that engineers and scientists are questioning whether airplane seats are adequately constructed to protect overweight travelers. Government standards for airplane seat strength -first set more than 60 years ago---require that the seats be made for a passenger weighing 170 pounds(77kg).Today, the average American man weighs nearly 194 pounds(88kg) and the average woman 165 pounds(75kg).Negroni reports: "If a heavier person completely fills a seat ,the seat is not likely to behave as intended during a crash,"Robert Salzar,the leading scientist at the Center for Applied Biomechanics at the University of Virginia. "The energy absorption(,) that is built into the aircraft seat is likely to be overpowered and the passengers will not be protected properly". "Nor would the injury be limited to that passenger only," Dr. Salzar said. "If a seat or a seat belt fails,"he said, "those people who are seated nearby could be endangered from the uncontrolled movements of the passenger." Most complaints about airplane seats focus on their lack of comfort and high ticket price, and whether overweight passengers should be made to buy two seats. But The New York Times' article bring up another reason to feel anxious about flying. Investigators of the issue got in touch with the airplane seat and seat belt makers, but they refused to comment on the problem.Experts agreed that crash testing should be done with overweight dummies .Both airplane seats and seat belts should be tested, _ said. Fortunately, however, according to Nora Marshall, a senior adviser at the National Transportation Safety Board, the board's investigators have never seen an accident involving a... Question: What is the article in The New York Times mainly conceerned with? - The size of airplane seats and seat belts - Safety of overweight airplane passengers - Airplane crashes involving commercial planes - A medical problem caused by being overweight
Safety of overweight airplane passengers

Ques: Read the following article and select the best answer. Article: What would we do without humour? How would we enjoy speaking with others if we did not use humour to invite a smile or a laugh? And how would we manage in times when we feel sad and lonely? Using humour we lighten up each day, and we find common ground with others. We build healthy relationships with others by knowing what to say and what to do. When our use of humour is successful, we build trust and cooperation. We discover that we are not alone, we learn to accept our mistakes, and we look for the good in others and in ourselves. Most importantly, we create common ground, as humour is an essential skill needed to communicate well with others. A few well-chosen words get the attention of others and make a serious point without their getting defensive . Whether we prefer to be the centre of attention or to be shy and quiet, humour can be adjusted to suit our personality. However, when we lose our sense of humour, we often get critical or defensive, and we blame others or ourselves for what was said, and how it was said. To ensure that our humour is welcomed by others, we need to combine our humour with speaking clearly and listening effectively.

Read the following article and select the best answer. Article: Plants need green leaves to make food. A plant needs sunlight and carbon dioxide from the air for making food and it also needs water and salts from the soil to make food too. There are certain cells in the leaves which change carbon dioxide and water into sugar. To do this the cells needs energy, which they get from the sunlight. Green leaves make food for the whole plant. A red leaf can make food too because under the red color1ing of the leaf there are food----making cells. There are no leaves which are completely yellow, for they can't make food. The plant makes sugar for its food. In sunlight green leaves make a lot of sugar. The veins can't carry all this sugar away, so the leaves change the sugar into starch , which is kept and so stored in the leaves. At night, the starch changes back to sugar. It is then carried away from the leaves. Some of the sugar is used as food by the plant while the rest is stored as starch. In some plants, food is stored in the roots, in others it is stored in the stem and in leaves, fruits and seeds. Question: To make food, plants need a lot except _ . - the air - the soil - the green leaves - dead leaves
dead leaves
