Teacher: In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.
Question: Researchers did experiments on kids in order to find out _ .
Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness
Answer: B
Solution: Yes
Reason: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. Hence, B is the correct answer and output is Yes.

Now, solve this instance: Article: If you are ever planning to buy a telescope and want to get yourself involved in astronomy it is always a good idea to know a bit of the sky.Get acquainted with a few constellations so that it will be easier for you to spot the constellations when you are using your telescope. It's a good idea to buy a few magazines on astronomy to help you to get familiar with the constellations in the sky and also read a few reviews on the different types of telescopes in the market.This will help you gather all the information that is out there regarding telescopes and what people have to say about them. It's advisable to go in for a pair of binoculars before you buy your first telescope so that you can get used to spotting constellations before your view of the sky is narrowed down.This will also help you know if you really want to get involved in astronomy.Many people buy a costly telescope and then discover that they're not actually interested in astronomy. Experience has no substitute,and there certainly is nothing better than using different telescopes before you buy one.This will help you to get the feel of all the types of telescopes and you will know which one is easier for you to use.A large aperture refractor may give you an excellent image but you may not be able to keep a steady hand while using it resulting in a blurry image. There are three types of telescopes that are available in the market.If you want a more elegant looking telescope you can always choose to buy a fine brass telescope.It's good to become acquainted with each type before going for the plunge of a first telescope.The first type of telescope is the refractor telescope,which uses lenses to gather light to a focus at the eye piece.The use of lenses helps the telescope have a superior image.A refracting telescope is not as portable as the other two types of telescopes and so you will have to buy one with a small aperture. The second type of telescope is the Reflector.Made by Sir Isaac Newton,this telescope functions by focusing the light back at the front of the tube,which is where the eyepiece sits,by using parabolic mirrors and another smaller mirror to deflect the light.There is no added color in the image caused by refraction of light since this telescope does not use lenses.These are the cheapest of all telescopes and are more portable than refractors.
