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.

Q: Article: NOT all math skills are learned in the classroom. Some of them come naturally. Consider the split-second calculations you make when you estimate the number of empty seats on the school bus or the number of cookies in a cookie jar. These estimates can often be done without counting. That's because humans are born with the ability to closely guess the number of items in a group. Researchers call this ability a person's "number sense". To see how a person's inborn number sense might be linked to mathematical performance in the classroom, psychologist Justin Halberda and his colleagues from Johns Hopkins University in prefix = st1 /Baltimore,USran some tests. The scientists asked 64 14-year-olds to look at images of yellow and blue dots that flashed on a computer screen for a fraction of a second. Each image contained between 10 and 32 dots that varied in size. Some images contained twice as many blue dots as yellow dots. In other images, however, the number of blue and yellow dots was nearly equal. For each image, the students were asked to estimate which color1 had more dots. The scientists found a wide variation in how well students could pick the color1 with the most dots. The scientists then looked at the students' math scores dating back to kindergarten. Children that performed best in the image test also scored the highest in standard math tests. The same finding held true at the other end of the spectrum . Students who didn't score well on the image test received lower math scores. The study was the first to show a link between a person's inborn number sense and his or her achievement in formal math training. Does this connection mean that one cannot be good in math if they have a weak number sense? Or that having a strong number sense is a guarantee for good grades in math? The answers are not clear. While scientists continue looking at the possible links between a person's number sense and math achievement, one thing is certain: Doing lots of math homework will _ your chances of success.
Question: Which of the following is not true according to the passage?
Options: (A) Everyone has an inborn number sense. (B) Those who have a strong number sense are sure to do well in math. (C) Some of the math skills are inborn. (D) Doing a lot of math exercises may help to learn math well.
Asnwer: B

A: Yes

Q: Article: Today, Mount Qomolangma's peak is not a lonely place any more. More than 3,500 people have successfully climbed the 8,844m mountain, and more than a tenth of that number reached the peak just over the past year. As more and more people try to test themselves against Qomolangma, many a time the mount can be very crowded. Climbers have complained about waiting for hours in the bottlenecks on the way to the peak. If bad weather strikes, climbers can and do die. But the dangerous crowds aren't the only problem on Qomolangma. All those climbers need to bring a lot of _ --much of them ends up being left on the mountain, sometimes even the peak itself. Mount Qomolangma is becoming the world's tallest rubbish dump. Here's mountaineer Mark Jenkins writing in National Geographic about the state of Qomolangma: "The two standard routes, the Northeast Ridge and the Southeast Ridge, are not only dangerously crowded but also badly polluted." But the good news is that some mountaineers are taking it upon themselves to clean up Qomolangma. Mountaineer Paul Thelen and his friend Eberhard Schaaf are part of the annual Eco Everest Expedition, which has been cleaning up rubbish from base camps to the peak since 2008. So far they've collected over 13 tons of garbage. Some of that rubbish is even being used for a higher purpose. As part of the Mount Everest 8844 Art Project, a group of 15 artists from Nepal collected 1.5 tons of garbage brought down the mountain by climbers. They've changed the cans and oxygen tanks--in one case, part of the remains of a helicopter--into 74 pieces of art that have already gone on exhibition in Nepal's capital. Part of the profit from sales will go to the Everest Peakeers Association, which has helped collect tons of rubbish off the mountain.
Question: What do we learn about the bottlenecks on the way to Mount Qomolangma's peak?
Options: (A) They are relatively safe. (B) They are often crowded. (C) They are very easy to pass. (D) They are sites of base camps.
Asnwer: C

A: No

Q: Article: Women love shoes! They will sometimes go to look for the perfect pair of shoes to wear only once with the perfect outfit or the fashion of the day. Once worn, these fashionable designer shoes may spend weeks, months, or years in the closet without being worn again until another special occasion comes up. With that said, are expensive designer shoes really worth their cost? Historically, shoes were invented to free feet from sharp rocks, hot sands, and blisters. Shoes were made to be simple and functional, with tough leather soles and straps. As society became more sophisticated , the role of shoes changed; shoes were made to add status to the wearer. Shoe designers began to work on the production of fashion shoes for the wealthy; shoes meant more for show than for practical use or simplicity. Good shoemakers became well known and printed symbols on their shoes, so people could recognize the maker of that particular design. Designer shoes were thus born. Many women develop serious problems with their feet after wearing these designer shoes during the workday and the medical costs for dealing with these problems can get very high. Some popular makers of designer shoes have been working towards combining comfort and practical use into their shoes, but it has been noted that women still go for style, beauty and uniqueness above everything else. So to answer the question as to whether or not designer shoes are worth the cost, the answer is certainly yes, but be smart and invest in a pair of comfortable, not so stylish shoes for the days when you stay outdoors for hours! They can also be very expensive, but I can surely say that they are worth the cost.
Question: When shoes were first made, their main use was to _ .
Options: (A) increase the wearer's image (B) protect the wearer from discomfort (C) make the wearer more noticeable (D) show the simplicity of life
Asnwer: C

A:
No
