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.

Input: Consider Input: Article: Cats have an amazing sense of smell, which is something like 12 times that of humans. Your cat is able to smell, whether you know it or not, whenever you come home or enter a new space. They can tell who you are, where you were an hour ago and sometimes even what you had for breakfast! Some people believe that cats can smell illnesses not only in themselves and other cats, but in humans as well. Cats also have an extra sense organ that is unique to cat's family. The "Jacobsen's organ" as it is known, can be described as somewhere between smell and taste. It separates tastes particles from the air, allowing the cat to "taste" whatever it can smell. Therefore, you may sometimes have seen a cat with its mouth slightly open and perhaps its tongue just a bit out when it is smelling smells. Whenever my cats do this, they seem to have a look of deep concentration on their faces. A cat's smell is so good that it can recognize each ingredient in foods. Very few smells are dislikable to cats, so mothballs have always been used to keep cats off gardens, since cats cannot stand the smell of them. Smells are also very important to your cat. They can recognize boundaries (,), people, other animals, food, and their environment. Your cat will walk around, checking for new things and will smell the slightest change. A cat can tell not only who you are, but also your general health and attitude, all from smells.
Question: According to the passage, we can learn that _ .
Options: (A) cats can tell what you did before you came home (B) cats can cure your diseases with the Jacobsen's organ (C) cats' sense of smell is much stronger than humans' (D) you will stay healthy if you keep a cat at home
Asnwer: C

Output: Yes

Input: Consider Input: Article: Skipping classes, particularly big lectures where an absence is likely to go undetected, is a tradition among college undergraduates. These days, however, some professors say they're seeing more _ , as students make the most of new technologies as learning aids. Americ Azevedo taught an "Introduction to Computers" at the University of California, Berkeley, US last semester. By visiting the course's website, the 200 enrolled students could download audio recordings or watch digital videos of the lectures, as well as read the instructor's detailed lecture notes. But there was one big problem: So many of the undergraduates relied on the technology that at times only 20 or so actually showed up for class. Doug Suda, 19, a student in Azevedo's class last semester, said he skipped about three-quarter of the lectures. It's largely because he was busy with an off-campus job and was taking the course to fulfill a business major requirement. At the end of the term, Suda prepared hurriedly for the final exam by watching videos of about 15 lectures over three days. "If I hadn't that... I would probably fail the class," said Suda, who instead received a B-plus. Despite the concerns about absenteeism, schools are increasingly experimenting with ways to let students watch or listen to lectures on their computers or digital music players, like iPods. Last month, Harvard Medical School began "Podcasting" lectures. Students can download them into digital musical players, and study while they, say, go for a walk. As many academics accept the electronic innovation, others are pushing back. To encourage attendance, they are applying low-tech tactics, like giving more surprising quizzes or cutting back their online offerings. Lee Chanian, a UCLA economics professor, says "too much technology leads to passive learning environment and encourage more absenteeism". He now puts fewer lecture materials online, and provides extensive notes only for the most complicated topics.
Question: At times only 20 or so undergraduates showed up for Americ Azevedo's class because _ .
Options: (A) so many undergraduates relied on digital learning aids (B) so many undergraduates have off-campus jobs. (C) his lectures were boring (D) the exam was easy to pass
Asnwer: D

Output: No

Input: Consider Input: Article: It came as something of a surprise when Diana, Princess of Wales, made a trip t Angola in 1997, to support the Red Cross's campaign for a total ban on all anti-personnel landmine landmines Within hours of arriving in Angola, television screens around the world were filled with images of her comforting victims injured in explosions caused by landmines. "I knew the statistics," she said. "But putting a face to those figures brought the reality home to me; like when I met Sandra, a 13-year-old girl who had lost her leg, and people like her." The Princess concluded with a simple message: "We must stop landmines". And she used every opportunity during her visit to repeat this message. But, back in London, her views were not shared by some members of the British government, which refused to support a ban on these weapons. Angry politicians launched an attack on the Princess in the press. They described her as "very ill-informed" and a "loose cannon" . The Princess responded by brushing aside the criticisms: "This is a distraction , we do not need. All I'm trying to do is help." Opposition parties, the media and the public immediately voiced their support for the Princess. To make matters worse for the government, it soon emerged that the Princess's trip had been approved by the Foreign Office, and that she was in fact very well-informed about both the situation in Angola and the British government's policy regarding landmines. The result was a severe embarrassment for the government. To try and limit the damage, the Foreign Secretary, Malcolm Rifkidnd, claimed that the Princess's views on landmines were not very different from government policy, and that it was "working towards" a worldwide ban. The Defense Secretary, Michael Portillo, claimed the matter was "a misinterpretation or misunderstanding." For the Princess, the trip to this war-torn country was an excellent opportunity to use her popularity to show the world how much destruction and suffering landmines can cause. She said that the experience had also given her the chance to get closer to people an their problems.
Question: Princess Diana paid a visit to Angola in 1997

Asnwer: D
