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: Farming is moving indoors, where the sun never shines, where rainfall is irrelevant and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature, wetness, air quality and nutrition. It could be in a New York high-rise or a sprawling complex in the Saudi desert. It may be an answer to the world's food problems. The world is already having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those--about 3 billion--are hungry or ill-fed. Food prices, currently increasing, are _ by dryness, floods and the cost of energy required to plant, harvest and transport. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world are already using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6. 8 billion to 9 billion. To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to completely increase crop output. Gertjan Meeuws has taken the concept of a greenhouse a step further, growing vegetables and house plants in enclosed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating similar day and night, but according to the rhythm of the plant. A building of 100 square meters and 14 layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch, about 140, 000 people. Their idea is not to grow foods that require much space, like corn or potatoes. Here sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoors agriculture. And city farming means producing food near the consumer, and there's no need to transport it long distances.
Question: It can be inferred from the text that Gertjan Meeuws's farming _ .
Options: (A) helps save sea water a lot (B) suits different conditions (C) is completely different from greenhouse agriculture (D) suits the production of corn
Asnwer: B
Example Output: Yes

Example Input: Article: Vancouver. B.C.--For six months. Ted Schredd and Deanna Kopel cycled around North America to show others a way to help the environment. "Nobody wants to breathe dirty air--but for the air to change. People have to stop driving cars," says Ted, "If more people start riding bikes, the air will be cleaner." Ted started his trip alone. He had $160 in his pocket and plans to cycle around North America. He left his hometown of Vancouver, and when he arrived in San Diego he got the chance to make some extra money for the rest of his 13, 000 km trip. A cyclist he met asked him to speak at an environment meeting in Texas. Within a few hours, Ted was on a plane to the meeting and a big surprise. When he met Deanna at the meeting, they talked for six hours straight. It was love at first sight. The next day, he called her to ask if she wanted to finish the trip with him. She said yes, sold everything in her flat, gave her notice at work, and was on the road with Ted three weeks later. Deanna found Ted's timetable difficult because he got up early in the morning. Deanna was a nurse and usually worked at night. "All of a sudden, I was up at six when I wanted to sleep until noon," said Deanna. As the couple cycled to Florida and up to Montreal and then back to Vancouver, every day was an adventure. They got free meals in restaurants, and slept in people's yards. When they ran out of money, people gave them extra cash. Sometimes people gave away $50 or $100. And like all good stories this one has a happy ending. On the way back to Vancouver, they stopped in Edmonton to visit Ted's relatives. During the visit, they got married. People tied ten cans and a "Just Married" sign to the back of their bikes. They now want to write a book about their trip. "We want people to know that you can protect our earth and still have fun," Schredd said.
Question: What did Ted Schredd believe to be a way to protect the environment?
Options: (A) Driving less. (B) Breathing clean air. (C) Saving waste tin cans. (D) Staying healthy by cycling.
Asnwer: B

No
