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: It could happen just about any time you step out in public. You get onto an almost-empty bus, but the next passenger in decides to ignore dozens of empty seats to sit right next to you. While you're waiting in line at a supermarket, the next customer insists on standing only two inches behind you and shouting into his cell-phone. You go into a public restroom, and the next person to enter decides to use the next stall. Transgressions  like these don't just make us feel uncomfortable; we often feel anxious, alarmed; and violated . It is the attack of the personal-space invaders. In any society, shared definitions of personal space govern how we interact with other people. People living in densely  populated cities like Mumbai, Beijing, or Mexico City tend to require less personal space than people living in sparsely  populated places within the country. In America, New Yorkers often have smaller requirements than residents of western states, like Montana, Shenandoah and Wyoming. Because everyone has different standards, gestures that are innocent in one place can be interpreted as opposite in another, especially in Britain. As the British etiquette  website Debrett puts it, as a British person, somebody standing too close may make you "focus less on what somebody is saying than on how close they are to you". Simple acts like putting an arm around someone you don't know may seem friendly in China, but they can make us very uncomfortable. People from many European countries such as France and Spain kiss each other on the cheek when they meet, yet to British person, this seems too friendly and "touch-freely". The website explains! "The British are not backslappers  and generally do not show affection in public". Are British people unfriendly? Far from it. The website adds that they are not as " _ ' as they may seem, but very friendly and helpful to foreigners. However, remember not to be too close. If you are going to come closer than an arm's length, please let them know. 
 Question: According to the passage, if you were meeting a British for the first time, it would be polite of you to   _  . 
 Options: (A) kiss him/her on the cheek (B) keep an arm's length away from him/her (C) put an arm around him/her (D) slap his/her back 
 Asnwer: B

Output: Yes


Input: Consider Input: Article: Recently a committee of the National Academy of Sciences inprefix = st1 /Washingtonreleased a report .It confirmed that world temperatures increased about six-tenths of a degree Celsius in the last one hundred years. The report also confirmed evidence that the level of carbon dioxide in increasing.        The best information about climate in the past comes from tests of ice many kilometers deep in Antarctica and Greenland .These tests show that levels of carbon dioxide today are the highest ever measured .These findings have led scientists to believe that carbon dioxide is a major cause of climate warming.        Carbon dioxide is released into the atmosphere when fuel is burned. Oil ,coal and wood are all fuels that release the gas .When biological waste breaks down ,it also releases carbon dioxide.        However ,plants use carbon dioxide in the process called photosynthesis. This process provides food for almost all life on Earth. Some groups that support burning oil and coal want to increase the amount of carbon dioxide in the atmosphere . They oppose international efforts to control carbon dioxide.        Some scientists believe that forests and trees are able to capture large amounts of carbon dioxide from the air. Some groups even suggest that an increase in carbon dioxide could cause plants to grow faster.        A recent study inNorth Carolinafound that more carbon dioxide in the air could cause trees to grow faster .But the researchers found the effect appears to last for only three years. Another study showed that much of the carbon dioxide that is taken in by trees in released within three years. The study noted that leaves released carbon dioxide when they fall from trees and break down in the soil. Plants also naturally release carbon dioxide  through the process of respiration. 
 Question: Which one is NOT mentioned in this passage that can be the source of carbon dioxide? 
 Options: (A) Oil (B) Trees (C) Wood (D) Soil 
 Asnwer: A

Output: No


Input: Consider Input: Article: I had recently arrived in London and I wanted to see some of the famous places. Should I go to the seaside? Or maybe one of the famous parks? I walked along the street, past a kindergarten playground, and suddenly saw an underground railway station. I was surprised because it was not on my map. I went to buy a ticket. The ticket-seller looked very old. He gave me a ticket, said "Remember it's a return", laughed and walked away without taking my money. Was it special for tourists? A train arrived. I could not see any other passengers. I got on and the doors closed. I suddenly felt I should not have got onto the train. It started to go faster and faster, shooting along the tracks. As it entered the tunnel, everything became as dark as midnight and I do not remember the next few minutes. The train came to a station and I got out. I could see light shining in the distance so I walked towards _ and came to a door. Beyond it there was a busy street. There were lots of English people walking about, and I could see some of the famous buildings of London, but there was something wrong. The people's clothes were strange. There were no cars, no motorbikes--but there were horses everywhere. Was someone making a film? "Excuse me," I said to a man. "Would you mind telling me where I am and what is happening?" "What do you mean? Who are you? Where do you come from? Are you from China? This is London and everyone's going to work. Can't you see that?" he asked. "Thank you, sir. I'm sorry, but could I look at your newspaper?" I asked. "You can have it," he said as he walked off. I looked at it; I saw "New Bicycle Law" and above that "July 5, 1880". Maybe I should have walked around, but I ran back to the door. I waited a long time. I was very afraid. A train came. I got on. It took me back to the first station. As I left, a woman asked, "What were you doing in that abandoned station?" I had no answer, but I still had the newspaper in my hand. 
 Question: Why was the author surprised at the beginning of the story? 
 Options: (A) Because he suddenly saw an underground railway station. (B) Because he walked past a kindergarten playground. (C) Because the ticket-seller looked very old. (D) Because he couldn't find the station on his map. 
 Asnwer: C


Output: No
