Does a drink a day keep heart attacks away? Over the past 20 years, numerous studies have found that moderate alcohol consumption, that's to say, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease. Last week a report in the New England Journal of Medicine added strong new evidence in support of that theory. More important, the work provided the first solid indication of how alcohol works to protect the heart. In the study, researchers from Boston's Brigham and Women's Hospital and Harvard Medical School compared the drinking habits of 340 men and women who had suffered recent heart attacks, with those of healthy people of the same age and sex. The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are. The apparent source of the protection:those who drank alcohol had higher blood levels of high-density lipoproteins , the so-called good cholesterol , which is known to prevent heart disease. As evidence has mounted, some doctors have begun recommending a daily drink for patients of heart diseases. But most physicians are not ready to recommend a regular happy hour for everyone. The risks of teetotalling are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles--not to mention violent behavior and traffic accidents. Moreover, some studies suggest that even moderate drinking may increase the incidence of breast and colon cancer. Until there is evidence that the benefits of daily dose of alcohol outweigh the risks, most people won't be able to take a doctor's prescription to the neighborhood bar or liquor store. Experiments showed that nondrinkers had _ . A) larger amounts of good cholesterol B) smaller amounts of good cholesterol C) higher blood pressure D) lower blood pressure

Motorists over the age of 75 face compulsory tests of their eyesight and ability to drive under proposals being considered by ministers. The biggest _ of motoring law in a generation could also lead to all drivers having to give assurances of their fitness to get behind the wheel every 10 years. Other changes under consideration include issuing daylight driving licenses for motorists with night blindness, together with stricter checks on all drivers whose medical condition brought a threat to other road users. It is understood that the proposals will be part of a review of the law governing the medical fitness of drivers that will be announced publicly by the summer. The Driver and Vehicle Licensing Agency is dealing with a rising number of motorists who are concerned that they have conditions---from failing eyesight to epilepsy---that could affect their driving. In 2006, the DVLA dealt with 600,000 motorists whose physical ability to drive needed to be recertified , a 20 per cent rise on the previous year. With an ageing population, the biggest challenge is dealing with the rising number of elderly motorists. By 2021, there will be an estimated three million drivers over the age of 70 on Britain's roads. Drivers must renew their licenses at the age of 70 and every three years thereafter. The applicant is legally required to tell the DVLA of any conditions that could weaken their ability behind the wheel. Ministers have ruled out a compulsory maximum age for driving but will instead rely on tightening up the checks on motorists over the age of 75. The most likely option would be tests to ensure motorists were fit to drive. They would include an eyesight test and a cognitive test that would prove a driver's ability to react to road signs, driving conditions, pedestrians and vehicles. However, checks are likely to be tightened at all ages. The strictest controls are expected to be imposed on motorists of any age who have had a heart attack or stroke. They could have to produce a doctor's approval to resume... Which of the following statements is TRUE according to the passage? A) The new motoring law will come into effect by the summer. B) Drivers over the age of 75 must renew their licenses every three years. C) Doctors will decide whether one can get their driving licenses. D) Drivers at all ages will be expected to provide their medical condition.

Ques: Nowadays women appear to have a positive image of themselves as safer drivers than men. In a survey done for insurer MetLife, 51% of women said they drive more safely. The evidence is on their side: Men are 3.4 times more likely than women to get a ticket for careless driving and 3.1 times as likely to be punished for drunk driving. "Women are on average less aggressive and more law abiding drivers, which leads to fewer accidents," the report says. However, not all male drivers share the same opinion. Of the men surveyed by MetLife, 39% claimed male drivers were safer. The findings did back them upon one point: automotive knowledge. The report showed that more men are familiar with current safety equipment such as electronic stability control,which helps prevent rollover accidents. Auto safety unavoidably matters to Money. Insurance companies focus on what classes of drivers have the lowest dollar amounts of claims, and for now, that mainly includes women. In general, women pay about 9% less for auto insurance than men. A study by the website Insweb also showed that auto insurance rates are lower for women in most states. Among individual states, women get the greatest, advantage in Wyoming (where they pay 20% less), South Dakota and Washington, D.C, where their insurance costs are 16% lower. "More than 11,900 male drivers died in US traffic accidents in 2009,compared with just under 4,900 women drivers" according to the study. "Based on miles traveled, men died at a rate of 2.5 deaths per 100 million miles traveled, vs.1.7 deaths for women." According to the study,female drivers _ . A) are more aggressive while driving B) are more interested in auto knowledge C) are more likely to stick to driving laws D) are more familiar with safety equipment
Ans: C
Recently I was asked,"Are we anywhere near the day when you can climb into a car on Long Island, program it to take you to your niece's house in Chicago, hit enter, and after the first hundred yards, once you hit a main road, the car takes over automatically and you just sit back and enjoy the ride?" It is a question I worry. But I had to answer truthfully:"Absolutely. We are without a doubt near that day."Look, we're already doing it with airplanes. Northrop Grumman's Global Hawk takes off at an air base in the U.S., climbs to 50,000 feet, flies to Australia, and lands at an Australian air base, where there is a grandstand filled with military officials=with no human pilot. The necessary technology is already here. We have radar technology that can be tied to cruise control and brakes, which automatically adjusts your speed based on following distance and preprogrammed settings. It's still a little bit raw, but it does work great. The technology can allow cars and trucks to follow each other in very closely spaced roads. GPS can also change speed with location. Let's say you're in a state with a 75-mph limit and you cross into a state with a 65-mph limit. GPS knows that and adjust your speed accordingly. It's not out of the question to imagine that someday soon you'll be able to start the car, make proper settings, then turn the front seats around and play cards and eat lunch as if you're riding on a train. All in perfect comfort and safety, all the way to that niece's place inprefix = st1 /Chicago. If asked to estimate just how far time is, I'd say a working system is ten years out, practice maybe 20 years. Which of the following may be the best title for this passage? A) Driving is dead? B) Cars in the future C) New technology will change cars? D) Comfortable car driving
