Write a multi-choice question for the following article: Article: Spending just a few hours a week online may make people feel more socially isolated , lonely and downhearted , according to a two-year study of nearly 100 families with the Internet. "We were surprised to find that social technology has such bad effects on social communications," the lead author, Dr. Robert Kraut of Carnegie Mellon University in Pittsburgh, Pennsylvania, said in a statement to the news. The findings suggest that "Rather than encourage students to use the Internet alone for research, teachers might give pupils online group homework to complete with classmates. Local groups might build websites that allow neighbors to discuss local affairs ." "Before the technology develops and can be really more _ , people shouldcontrol their wishes to use much of the Internet," Dr. Kraut and other experts advise. In order to control their children and encourage family activities, parents might think of putting the computer in the living room rather than in a child's room, they suggest. Dr. Kraut also suggests that when surfing on the net, especially when chatting with strangers on the net, children should not use their real names, and that they should not tell the addresses, telephone numbers to the strangers.

Q: Write a multi-choice question for the following article: Article: Getting too little sleep or not spending enough time in rapid eye movement(REM) sleep is connected with being overweight among children, according to a new study. For three nights, researchers studied the sleep patterns of 335 young people, aged 7 to 17. They looked at total sleep time, time spent in REM, time it took to fall asleep. Body-mass index was checked at the start of the study, and 45 persons in the research were overweight, while 49 were at risk of becoming overweight. Compared to normal-weight children, those who were overweight slept about 22 minutes less per night and didn't sleep as well as them, which means shorter REM sleep, less eye activity during REM sleep, and a longer wait before the first REM period. After more research, the researchers concluded that one hour less of total sleep was connected a double increased risk of being overweight. One hour less of REM sleep was connected with a three times increased risk. Although the reasons are still being researched, the relationship between short sleep duration and overweight may be the result of behavioral and biological changes, which are caused by sleep loss, wrote Dr. Xianchen Liu of the Western Psychiatric Institute and Clinic in Pittsburgh and his colleagues. They explained that sleep loss causes changes in hormone levels that may have an effect on hunger, and less sleep also means a person has more waking hours in which to eat. Sleep loss also leads to tiredness the following day, which may lead to less physical activity and fewer calories burned.
