Online shopping is becoming more and more popular for a number of reasons: prices are often lower online, you don't have to queue up in busy shops and you can buy almost any product imagin- able with just a few clicks of your mouse.

Article: It seems like every day there's some new research about whether our favorite drinks are good for us.  One day,  science says a glass of red wine a day will help us live longer. The next day, maybe not.  It seems journalists are pretty interested in wine research and the same might be said for coffee.  Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed",admits Neal Freedman who led the coffee study and published his findings in a medical journal recently.   "There's been some evidence that coffee might increase the risk of certain diseases and there's also  been  maybe  more recent evidence that coffee  may protect against other diseases as well". Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health.  They analyzed data collected from  more than  400,000 Americans ages 50 to 70 participating in the study.  "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers, he said.  Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the  risk  of  dying from  heart  disease, lung  disease injuries,  accidents  and infections. Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship.  All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.

 Options: (A) Freedman and his colleagues hired 400,000 Americans to collect date. (B) People who took part in Freedman's research are about 50 to 70 years old. (C) About 400, 000 Americans worked for Freedman's team for 13 years. (D) People who are 50 to 70 years old seldom drink wffee.

Article: My parents moved to Mississippi when my brother and I were small children, and we were separated from our Oklahoma grandparents by some 600 miles. This long distance allowed us to only visit our grandparents once a year, either at Christmas or during summer vacation. Most of my classmates lived near their grandparents, and I would often hear stories of big families regularly spending time with one another, fishing at "grandpa's" house or going over to "grandma's" for her famous fried chicken. We were disappointed that we did not get to spend more time with our grandparents, but our love for them remained deep and strong. We always expected a road trip to Oklahoma. We would count the days, and when the day came, the entire family would pile into our car at four o'clock in the morning. Crossing the Mississippi River into Louisiana, the scenery changed. Crossing the Red River in Oklahoma, we were in a foreign world. Every trip to see my grandparents can't be without bringing delight. We jumped out of the car in their driveway to be met with bear hugs. My grandparents wanted to know everything about their grandchildren, and we would sit for hours and tell story after story. Grandma had a meal planned, and you could guess she prepared her grandsons' favorite foods. Of course the best part of the visit was that we were able to do whatever we wanted without punishment from our grandparents. Grandma and Grandpa always had presents for us, short trips planned and lovely surprises, such as the time we got to a local restaurant and ate the world's largest hamburger. 
 Question: Why didn't the family visit their grandparents often? 
 Options: (A) Because they seldom had a vacation. (B) Because they had a bad attitude to them. (C) Because they were all busy with their work. (D) Because they lived far away from each other.
