input: Please answer the following: Write a multi-choice question for the following article: Article: This is a dangerous world we live in. The numbers of murders goes up every year;people are dying of cancer;more people contract HIV;more teens are using drugs;etc. You know this because you've heard all the statistics on the news. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background, statistics mean very little. This growing trend of reporting only part of the information is becoming dangerous.For example, several years ago a high school student reported dangers of the chemical known as dihydrogen monoxide . This chemical, found in most cancerous tumors , is found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth. The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical's full background. The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really more dangerous? If you think about it, you will realize far fewer people go skiing each year than the number of people who are in danger of a lightening strike. When you think about...

input: Please answer the following: Write a multi-choice question for the following article: Article: I was asked in an email about learning idioms in a foreign language. Maybe I am different from most people,but I do not bother with them. To me they are kind of dessert of language learning. They come at the end of a meal. Once you have filled up with the key words and phrases that are used in a variety of situations,then you can add a few idioms. And by that time, you will be able to pick them up naturally anyway. I find that many learners have trouble with idioms,as if repeating some very colloquial expressions is going to upgrade how they sound in a language. In fact, it is the opposite. Idioms are difficult to use correctly. Yes,occasionally you hear idioms and do not understand. But,in my experience,there are always situations where you do not understand. It is best to focus on the most important words,what they mean and how they are used. Certainly,it is best for a nonnative speaker to stick to standard speech. Some teachers even try to teach the "real language".Then you hear nonnative speakers saying things like "I goanna", "You wane" etc. You will learn all the idioms you need just by exposing yourself to the language. In general,you can save any phrase that you find interesting,and if that includes idioms,go to it. But I would not make any special effort to go after idioms. I,in fact,avoid them. If I come across something in Russian that strikes me as a particularly idiomatic use of words,I just leave it aside; do not even bother trying to learn it. If it keeps on appearing,then I will learn it.

input: Please answer the following: Write a multi-choice question for the following article: Article: You're on the third lap around the car park, there are no open spaces, and you're already 15 minutes late for your appointment. Right now you're wishing you could jump out of the car and let it go to find its own spot. Now there's an app for that. Virtual Valet lets your smartphone tell your car to park without you in it. "You pull up to the roadside, push a button on your smartphone and the car takes care of everything else," says Aeron Steinfeld, the lead researcher for the project at Carnegie Mellon University in Pittsburgh, Pennsylvania. To find its own spot, the system uses a sensor suite similar to ones found in many luxury cars. This includes a motion sensor that scans for moving cars and pedestrians, and a forward-facing laser rangefinder normally found in adaptive cruise control to determine the distance of objects in front of the car. Information from these sensors is then fed to an onboard computer to plot the vehicle's course. The users can watch the whole process from their phone. Better still, it will be affordable. The team has spent the last year moving from high-end imaging and processing equipment to less expensive components. In experiments, the vehicle was able to navigate through a crowded parking structure, find an empty spot, and park all on its own. And the greatest appeal of the Virtual Valet Parking App is that it requires no change to existing parking facilities or infrastructure. For the moment, the only car equipped for control by Virtual Valet is Carnegie Mellon' modified Jeep Wrangler, which the researchers have named NavLab11. But Steinfeld hopes that major car manufacturers will adopt the technology. It might be more than technology that holds up the show, however. Self-driving cars have been licensed in only three US states -- California, Nevada and Florida -- and it's unclear how this app would agree with self-driving laws. Until these questions are settled, your insurance provider might be unwilling to cover a ding from a parking incident.
