Write a multi-choice question for the following article, with the given choices and answer: Article: After a fortnight of extraordinary type, the much-feared computer virus that was supposed to strike the globe's hard drives last Friday simply fizzled. So many warnings were sounded that most computer owners either fed anti-virus programs into their systems or refused to turn the power on during the dreaded M-day. They dodged one disease, but more strains are on the way. The eponymous Friday-the-13th virus is due to strike this week, and the Maltese Amoeba may detonate on March 15. Who creates these things? A disproportionate number seems to originate in Bulgaria or Russia, where writing the smallest, most elegant virus programs has become a matter of quirky pride. Viruses are transmitted either by shared disks (as was Michelangelo) or over telephone lines. The virus program hides in a computer until, activated by a date, time, or some other trigger, it springs to life. The most common virus, Stoned, makes your screen announce: "Your computer is now stoned. Legalize marijuana. " (Regardless of your politics, you don't want this one around; it can damage your files inadvertently.) Solution: either keep your computer isolated--no trading disks, no on-line communication--or else install one of a dozen or so commercially available anti-virus programs that detect and delete the little time bombs. If they can come up with a virus that is hidden, will they next try to extort a business?--as in, pay me $1 million or my virus will destroy your system. In the meantime, money is being made by firms selling anti-virus programs. Egghead software stores logged a 3,000 percent jump in anti-virus sales. Was the threat overblown by the companies that make millions selling anti-virus software? Thanks to the media blitz, no one will ever know what might have happened--an unallied number of computer owners discovered and deleted Michelangelo before it was supposed to strike--on the artist's birthday. Options: A diseases spread from one computer to another by shared disks B viruses hidden in a computer's instructions by the designers C little time bombs hidden in a computer waiting to be triggered D just those computer programs created by malevolent designers Answer: D just those computer programs created by malevolent designers Question:
Ans: Computer viruses are _ .

Lyman can control the audio levels and activate speakers in various parts of his home as well as access different music services.

Write a multi-choice question for the following article, with the given choices and answer: Article: Among rich countries , people in the United States work the longest hours. They work much longer than in Europe. This difference is quite surprising because productivity per hour worked is the same in the United States as it is in France, Spain and Germany, and it is growing at a similar speed. In most countries and at most times in history, as people have become richer they have chosen to work less. In other words they have decided to "spend"a part of their extra income on a fuller personal life. Over the last fifty years Europeans have continued this pattern, and hours of work have fallen sharply. But not in the United States. We do not fully know why this is. One reason may be more satisfying work,or less satisfying personal lives. Longer hours do of course increase the GDP . So the United States has produced more per worker than, say,France.The United States also has more of its people at work,while in France many more mothers and older workers have decided to stay at home.The overall result is that American GDP per head is 40% higher than in France,even though productivity per hour worked is the same. It is not clear which of the two situations is better.As we have seen, work has to be compared with other values like family life, _ often get lost in interest.It is too early to explain the different trends in happiness over time in different countries.

Options: A Spain. B France. C Germany. D America. Answer: D America. Question:
Ans: Which of the following countries has more of its people at work?
