In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Example Input: Article: Gauri Nanda sees a wearable computer as a handbag -- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded in it. It looks, feels and weighs like your typical leather purse. That's where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf. Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle. As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse. Here's how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go. _ Indeed, more people will want to cross that bridge in the coming years -- making for a booming market for wearable computers that don't like something out of science fiction.
Question: Which of the following describes a wearable computer?
Options: (A) It can be washed in a washing machine. (B) It is much heavier than a leather purse. (C) It can download songs from the Internet. (D) It is made of clothes conducting electricity.
Example Output: A

Example Input: Article: The laptop is a machine which can be a mobile office;it can be used to entertain us and people can play computer games on them.One machine can perform many tasks at the same time.As technology grows,the size of the new laptop machines is _ .Now laptops are lighter,have smaller screen sizes,and perform better.Smaller screen laptops,which are more convenient to take along with,have been specially designed for professionals.Huge display screen laptops are still used by graphic designers and those who like playing computer games. Laptops are advanced machines,and they can be very expensive.When we spend much money on something,we should take good care of it.I know some people who buy a new laptop every year.The reason they do this is that the old one either is broken or has some problems which cannot be fixed.Common problems are the breaking of the screen,the breaking of joints of the laptop,display problems,and keyboard problems. Different problems will always come up with machines,and they cannot be avoided .Old machines will always have to be replaced by new ones.However,if we are more careful and handle our laptops with care,they will last for a longer period of time,and they will perform better.This is not a hard thing to do,but it will greatly increase the life and performance of laptops.
Question: We infer that graphic designers still use huge display screen laptops most probably because _ .
Options: (A) huge display screen laptops are very cheap (B) small display screen laptops are not on sale yet (C) they can see their drawings more clearly (D) they also want to play computer games
Example Output: C

Example Input: Article: Research shows that much of our predisposition towards determination, sociability and self - control and sense of purpose is in our genes.In fact, our DNA plays a bigger role in influencing these traits ( characteristics)than our upbringing and the company we keep.Taken together, these aspects of personality can make the difference between success and failure, say the Edinburgh University researchers. They questioned more than 800 pairs of twins about their attitudes to life to tease apart the influences of nature and nurture.Comparing identical twins, who share all their DNA and their up bringing, with non-identical twins, who have a shared background but are no more genetically alike than other brothers and sisters, is a technique often used by researchers to quantify the influence of genetics. The results, published in the Journal of Personality, showed that genes play a much bigger role than lifestyle, with self-control particularly etched into our DNA. Our genes a222so largely determine how determined and persistent we are.This is important in terms of success, as someone who refuses to give up is more likely to achieve their dreams than someone who _ Researcher Professor Timothy Bates said, "Ever since the ancient Greeks, people Lave de hated the nature of a good life and the nature of a virtuous life.Why do some people seem to manage their lives, have good relationships and cooperate to achieve their goals while others do not? Previously, the role of family and the environment around the home often controlled people' s ideas about what affected psychological well-being.However, this work emphasizes a much more powerful influence from genetics." However, those who haven' t been dealt a helpful hand of genes shouldn' t he too depressed.The professor says a sense of purpose is the key and advises those who are eager for success to focus their thoughts on making a difference.
Question: What does the result of the research indicate?
Options: (A) Our DNA is the only factor to decide our traits. (B) Our DNA plays a decisive role, in achieving success. (C) Education plays little part in the formation of our character. (D) Society has Little effect on us in our personality.
