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.

Example Input: Article: After two classes, I started to recognize several of the faces in each class. There was always someone braver than the others who would introduce themselves and ask me questions about how I was liking Forks. I tried to be , so mostly I just lied a lot to appear to be skilled at dealing with people. At least I never needed the map. One girl sat next to me in both Trig and Spanish, and she walked with me to the cafeteria for lunch. She was tiny, several inches shorter than my five feet four inches, but her wildly curly dark hair made up a lot of the difference between our heights. I couldn't remember her name, so I smiled and nodded as she gossiped about teachers and classes. I didn't try to keep up. We sat at the end of a full table with several of her friends, who she introduced to me. I forgot all their names as soon as she spoke them. They seemed impressed by her bravery in speaking to me. The boy from England Eric, waved at me from across the room. It was there, sitting in the lunchroom, trying to make conversation with seven curious strangers, that I first saw them. They were sitting in the corner of the cafeteria, as far away from where I sat as possible in the long room. There were five of them. They weren't talking, and they weren't eating, though they each had a tray of untouched food in front of them. They weren't staring at me, unlike most of the other students, so it was safe to stare at them without fear of meeting an over interested pair of eyes. But it was none of these things that caught and held my attention. I stared because their faces, so different, so similar, were all extremely, inhumanly beautiful. They were faces you never expected to see except perhaps on the airbrushed pages of a fashion magazine, or painted by an old master as the face of an angel. It was hard to decide who was the most beautiful -- maybe the perfect blond girl, or the bronze-haired boy.
Question: From the passage, we can infer that _ .
Options: (A) "I" was really liking the new place. (B) "I" had a bad memory, so it's hard to remember names. (C) "I" was good at making friends. (D) "I" was not interested in what the girl said.
Asnwer: A
Example Output: No

Example Input: Article: What doomed the Titanic is well known, at least in outline. On a moonless night of April 15, 1912, the ship hit an iceberg in the North Atlantic ,with 1,500 lives lost. A century later many people presented new theories to explain the real reason for the disaster. Now two new studies argue that rare states of nature played major roles in the disaster. The first says Earth's nearness to the Moon and the Sun -- a proximity not matched in more than 1,000 years -- resulted in record tides that help explain why the Titanic met with so much ice, including the fatal iceberg. Recently, a team of researchers found an apparent explanation in the heavens. They discovered that Earth had come unusually close to the Sun and Moon that winter, enhancing their gravitational pulls on the ocean and producing record tides. The rare orbits took place between December 1911 and February 1912 -- about two months before the disaster came about. The researchers suggest that the high tides refloated masses of icebergs traditionally stuck along the coastlines of Labrador and Newfoundland and sent them adrift into the North Atlantic shipping lanes. And a second, put forward by a Titanic historian from Britain, contends that the icy waters created ideal conditions for an unusual type of mirage that hid icebergs from lookouts whose duty was to watch carefully for danger ahead and confused a nearby ship as to the liner's identity, delaying rescue efforts for hours. Most people know mirages as natural phenomena caused when hot air near the Earth's surface bends light rays upward. In a desert, the effect prompts lost travelers to mistake patches of blue sky for pools of water. But another kind of mirage occurs when cold air bends light rays downward. In that case, observers can see objects and settings far over the horizon. The images often undergo quick distortions -- not unlike the wavy reflections in a funhouse mirror. Now, scholars of the Titanic are debating these new theories. Some have different opinions on it. Over all, though, many experts are applauding the fresh perspectives. (words:353)
Question: According to Theory Second, the disaster happened to the Titanic mainly because _ .
Options: (A) the freezing weather made the watcher not be able to watch clear (B) the mirage on the sea attracted the watcher and made him forget his work (C) the high tides drove the icebergs float so fast that the watcher didn't respond to them (D) the mirage made the watcher not find icebergs and a nearby ship delay rescuing
Asnwer: D
Example Output: Yes

Example Input: Article: Computer power is moving into the "cloud"--networks of data centres that use the Internet to supply all kinds of services, from e-mail and social networks to data storage and analysis. The rise of cloud computing is rapid and causing huge changes in the tech industry. The old guard is suffering: this week's $67 billion merger between Dell and EMC, makers of computers and storage devices respectively , was a marriage forced by the rise of the cloud. Disruptive newcomers are blooming: if Amazon's cloud-computing unit were a stand-alone public company, it would probably be worth almost as much as Dell and EMC combined. The gains for customers have been equally dramatic. Compared with older IT systems, cloud computing is often much cheaper. It adds tremendous flexibility: firms that need more computing capacity no longer have to spend weeks adding new servers and installing software. In the cloud they can get hold of it in minutes. Their applications can be updated continually, rather than just every few months. Individual users can reach their e-mails, files and photos from any device. And cloud services also tend to be more secure, since providers know better than their customers how to protect their computing systems against hackers. But cloud computing makes one problem worse. In the old IT world, once a firm or a consumer had decided on an operating system or database, it was difficult and costly to switch to another. In the cloud this "lock-in" is even worse. Cloud providers go to great lengths to make it easy to upload data. They accumulate huge amounts of complex information, which cannot easily be moved to an alternative provider. Cloud firms also create a world of interconnected services, software and devices, which is convenient but only for as long as you don't venture outside their universe. Being locked in to a provider is risky. Firms can start to tighten the screws by increasing prices. If a cloud provider goes bust , its customers may have trouble getting back their data. These risks have already caused a debate about whether the cloud needs stricter regulation. Some European politicians want to force cloud providers to ensure that data can be moved between them. That is too heavy-handed, because strict rules will inhibit innovation in what is still a young industry. The history of computing suggests that common standards may well appear naturally in response to customers' demands--just as in personal computers, where it is now much easier to use the same files on different systems. In the meantime, a few commonsense measures can reduce the risk of lock-in. Firms that use more than one cloud provider to host their data are less affected. So are those that keep their most important information in their own data centres. Consumers can take precautions, too. Some services are better than others at enabling users to move data between providers (Google does well on this score). Cloud computing promises its users many benefits, but don't mistake it for some sort of digital heaven.
