Article: Researchers continue to show the power behind our sense of smell.Recent studies have found,among other things,that the smell of foods like pizza can cause uncontrollable anger in drivers on roads. The review explains that smell is unique in its effects on the brain.According to Conrad King,the researcher who carried out the review,"more than any other senses,the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings.This is why the smell of baking bread can destroy the best intentions of a dieter." Smell,which dictates the unbelievable complexity of food tastes,has always been the least understood of our senses.Our noses are able to detect up to 10,000distinct smells.Our ability to smell and taste this extremely large range of smells is controlled by something like 1,000genes ,which make up an amazing 3% of the human genome.Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004for their ground-breaking research on the nature of this extraordinary sense.These two scientists were the first to describe the family of 1,000olfactory genes and to explain how our olfactory system works. According to one study in the research review,smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users.They are then more likely to speed and experience uncontrollable anger on roads.The most reasonable explanation is that these can all make drivers feel hungry,and therefore desperate to satisfy their appetites. In contrast,the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers'impatience.Similarly,the smells of lemon and coffee appeared to promote clear thinking and mental focus. However,the way genes regulate smell differs from person to person.A study by researchers in Israel has identified at least 50olfactory genes which are switched on in some people and not in others.They believe this may explain why some of us love some smells... Question: What is the passage mainly about? Yes or no, is the answer "Smell and its influence."?
(Answer)
No

"Now you can write the book you have always wanted to write.""But I have no job and no prospect (hope) of a job," he objected , completely without hope . "If I struggle to be an author, then what will we live on? Where will the money come from?" Sophia took her husband by the hand and led him to the kitchen, opening a drawer; she took out a box that was full of cash . "Where on earth did you get this?" Nate gasped. "To whom does it belong?"

Article: Picture this scene, a 6-year-old girl is alone on a raft, with no lifejacket, 200 yards from the shore with the winds whipping up the water. She is pointing at her cousins, and yelling out, "They are drowning!" Your eyes scan left only to see a three-year-old above the surface of the water and you realize two hands are holding her up, the hands of 14-year-old Mallory, who is struggling below the surface of the water. Three seventeen-year-olds from Salt Lake City, Tiana Skeen, Caitlin Caldwell and Jessica Osterloh, were on the lake for fun in the sun at Bear Lake when they heard the cry for help and saw this terrifying scene. The teens witnessed the three young girls in this very dangerous situation. The teens reacted quickly and swam out to save the girls while crying out toward jet skiers and people on the beach for help. Fourteen-year-old Mallory was struggling to hold her little cousin Rylee above water. The teens rescued Rylee just in time but couldn't find Mallory. Meanwhile, 6-year-old Sydney was floating away on the raft with no lifejacket. The girls flagged down a jet ski to get her and bring her back to the beach. The three teen heroines saved the 3-year-old and the 6-year-old, but they feel Mallory is the real heroine, as she held her 3-year-old cousin above the water until the teens were able to rescue Rylee. Mallory was finally found, but she died on the way to the hospital. Now, the teen heroines strongly remind everyone to wear a life jacket when on the water. Question: What was Mallory doing, when the accident happened? Yes or no, is the answer "She was trying to help her cousin survive."?
(Answer)
No
