Article: Why do men die earlier than women? The latest research shows that the reason could be that men's hearts go into rapid decline when they reach middle age. The largest study of the effects of aging on the heart has found that women's longevity may be linked to the fact that their hearts do not lose their pumping power with age. "We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age," "Within the heart there are millions of cells that enable it to beat. Between the ages of 20 and 70 , one-third of those cells die and are not replaced in men," . What surprises scientists is that the female heart sees very little loss of these cells. "This gender difference might just explain why women live longer than men," said Goldspink. The team has yet to find why aging takes a greater toll on the male heart, said Goldspink.. The good news is that men can improve the health of their heart with regular exercise. Question: We can know from the passage that _ . Yes or no, is the answer "scientists are still doing research into why the male heart loses more of the cells"?
No

Article: Just one bite of cake that is made with eggs is enough to make John feel very sick. Susan gets a terrible rash whenever she eats anything containing seafood, and David nearly died when he first ate a cookie that included peanuts. David had trouble breathing after he ate the cookie, but his mother knew what to do and she quickly gave him medicine that helped him feel better almost right away. The body's reaction to certain foods can be quite severe, resulting in breathing problems, as in David's case, or loss of consciousness for some. There are many things we eat may cause our bodies to react badly if we have a food allergy . The most common food allergies seem to be related to milk, soy, eggs, wheat flour, peanuts, nuts, and seafood. In fact, these kinds of foods account for 90% of food allergies. According to some studies, the number of children who have a food allergy is growing. But some people now argue that test results might not actually be accurate, so food allergies are not really as common as they may appear. There are three typical ways that doctors test for food allergies. Probably the most accurate way is for a doctor to give a child a food challenge", For this, the doctor watches the child eat small amounts of certain foods to see if the child has an allergic reaction or not. This method is very time consuming so it is used less often than the other two methods: skin tests and blood tests. In a skin test, a doctor puts very small amounts of the parts of the foods that the child may be allergic to under the child's skin, then watches to see if the child's skin reacts to the allergens . In a blood test, doctors take some of the child's blood and add possible allergens to it and then look for chemicals in the blood that indicate a possible allergic reaction. A problem with both the skin test and the blood test is that neither will show how severe an allergic reaction might be. If a test result is positive, the child may have a severe reaction by eating this food, but the child might just as likely... Question: What do skin tests and blood tests NOT show? Yes or no, is the answer "Whether allergic reactions are severe or not."?

No

Ques: Article: The other day I heard a few local musicians talking: "I hate all the pianos in this town and I hate that rubbish they play on the radio. They cannot even understand rhythm .""Nobody wants to pay musicians anything. I'm sick of all the people who want you to play without paying you."... One younger musician said, "There are a couple of clubs who want me to play for a few nights a month, and I'm trying to find other places to play. I'm also planning to join in several summer festivals this year." I really liked what the younger musician said so I made friends with him. Attitudes are important. Whether they're positive or negative , they're all rubbing off on you. If you're around people who are always complaining or blaming others, it is possible that you will start doing the same as well. If you spend lots of time with people who don't support your dreams, it is time to take a look at the people you call "friends". There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop spending time with the negative people on your list. Set a new standard for yourself and don't become friends with people who fall below that standard. The choice is always yours to make. Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream. Question: We can get the following information from the passage EXCEPT _ . Yes or no, is the answer "one should avoid making friends with people who have lots of difficulties"?
Ans: No

Ques:Article: Traffic Management Traffic lights are key tools for regulating traffic How.They are not, however, perfect.Drivers exchange the traffic jams that would happen at unmanaged crossings for a pattern of stop-go movement that can still be annoying, and which bums more fuel than a smooth passage would. Creating such a smooth passage means adjusting a vehicle's speed so that it always arrives at the lights when they are green.That is theoretically possible, but practically hard.Roadside signs wired to traffic lights can help get the message across a couple hundred metres from a crossing, but such signs are expensive, and are not widespread.Margaret Martonosi and Emmanouil Koukoumidis at Princeton University, and Li-Shiuan Peh at the Massachusetts Institute of Technology, however, have an idea that could make the process cheaper and more effective.Instead of a hardwired network of signs, they propose to use mobile-phone applications. For a driver to benefit, lie must load the team's software , named SignalGuru, into his phone and then put it on a special thing attached to the inside of his car's windscreen, with the camera lens pointing forward.SignalGuru is designed to detect traffic lights and track their status as red, yellow or green.It broadcasts this information to other phones in the area that are fitted with the same software, and --if there are enough of them ?the phones thus each know the status of most of the lights around town.Using this information, SignalGuru is able to calculate the traffic-light schedule for the area and suggest the speed at which a driver should travel in order to avoid red lights. Tests in Cambridge, Massachusetts, where five drivers were asked to follow the same route for three hours, and in Singapore, where eight drivers were asked to follow one of two routes for 30 minutes, revealed that SignalGuru was capable of predicting traffic-light activity with an accuracy of 98.2% and 96.3% respectively, in the two cities.This was particularly impressive because in Cambridge the lights... Question: Roadside signs wired to traffic lights are not the best way to create a smooth passage because _ . Yes or no, is the answer "they are too costly and not widely used"?

Ans:
No
