input: Please answer the following: Write a multi-choice question for the following article: Article: Unless you bring your own thermos, paper cups are the real option for on-the-go coffee. But as we all know, producing these simple items cuts down forests of trees and contributes to mountains of waste. In fact, Starbucks alone uses 4 billion paper cups a year globally and most of these plastic-lined cups are never recycled. But a project from Reduce. Reuse. Grow. is handling the coffee industry's paper cup problem by giving these single-use coffee holders a further purpose: reforestation. A company in California has developed the world's first plantable coffee cup, which has seeds in the paper-based material. That means after you're done with the cup, you can tear it, leave it in water for a few minutes, bury it and let nature take over. To prevent the spread of invasive plants, the bottom of the cup details the seed variety and also includes instructions on how to plant it either in the northern or central coast of California. For those who don't want to get their hands dirty, the cup can be put into a Reduce. Reuse. Grow bin where it will eventually be taken to a reforestation location. The cup can biodegrade within 180 days and offer nutrition to plants. The company is trying to put the cup into commercial production and persuade coffee shops to buy the cups.

Please answer this: Write a multi-choice question for the following article: Article: Can you smell two things at once? This experiment comes from the research of two scientists from Rice University. Denise Chen and Wen Zhou have been experimenting with the science of smell, and have made some very interesting discoveries. To explore that, you will need two things with strong, characteristic smells and, of course, your nose. The idea is to smell a different smell with each nostril . Hold one smell very close to your right nostril, and the other smell very close to your left nostril. Then breathe in and pay close attention to what you smell. What you should find is that one smell will be very strong. After another sniff or two, the first smell will go away, and you will smell the other smell. Keep sniffing, and the first smell will come back. Instead of smelling the two smells evenly mixed, they will work in turns, one after the other. Why? Chen and Zhou found that your sense of smell acts much like your sense of sight. Hold a book in front of your nose, so that your left eye sees things on the left side of the book, and your right eye sees things on the right side of the book. You will find that your sight works in turns, first on the left side of the book and then on the right side. Notice that you can't focus your left eye on one object while focusing your right eye on another object. Your brain jumps back and forth , paying attention to one and then the other. The same thing happens with your nostrils. If they are smelling different smells, your brain pays attention to one and then the other.

Problem: Write a multi-choice question for the following article: Article: My neighbor Mrs. Gargan first told me about it. "Have you seen the tree?" She asked as I was sitting in the backyard enjoying the autumn twilight . "The one down at the corner," she explained. "It's a beautiful tree--all kinds of colors. All the passers-by stop to have a look. You ought to see it." I told her I would, but I soon forgot about the tree. Three days later, I was jogging down the street when a splash of bright orange caught my eyes. For an instant, I thought someone's house had caught fire. Then I remembered the tree. I approached the tree to look at it closely. There was nothing remarkable about the shape of the tree. It was a medium-sized maple. But Mrs. Gargan had been right about its colors. Like the mess of an artist's palette , the tree blazed a bright crimson on its lower branches and burned with vivid yellows and oranges in its center, and deep red at its top. Through these colors were light green leaves as yet untouched by autumn. Walking closer I noticed several bare branches near the top, their small black branches scratching the air like claws. The fallen leaves lay like a red carpet around the trunk. As I was amazed at this beauty, I thought of Ralph Waldo Emerson's comments about the stars. "If the constellations appeared only once in a thousand years, imagine what an exciting event it would be. But because they're up there every night, we barely give them a look," he made a remark in Nature. I felt the same way about the tree. Because its beauty will last only a week, it should be especially precious to us. And I had almost missed it. Once in the 19th century when a man noticed a brilliant display of northern lights in the sky over Massachusetts, he rang a church bell to alert the whole town's people. That's what I felt like doing about the tree. I wanted to awake the countryside to its wonder. I didn't have a church bell, but as I walked home, I did ask each neighbor I passed the same simple but important question Mrs. Gargan had asked me: "Have you seen the tree?".

A: Question: How did the author call on people to enjoy the wonder?Options:A He rang the church bell.B He passed on the same question.C He awakened all neighbors up.D He required people to the corner.Answer:B

input question: Write a multi-choice question for the following article: Article: Many people say dolphins are very intelligent. They seem to be able to think, understand, and learn things quickly. But are they smart like humans or more than cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are similar in some ways. How? Fact 1: Talk to me Like humans, every dolphin has its own "name". The name is a special whistle. Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans, dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one speaks "dolphin" yet, but some scientists are trying to learn. Fact 2: Let's play Dolphins are also social animals. They live in groups, and they often join others from different groups to play games and have fun--just like people. In fact, playing together is something only intelligent animals do. Fact 3: Fishermen's helper Dolphins and humans are similar in another way: both make plans to get something they want. In the seas of southern Brazil, for example, dolphins use an interesting strategy to get food. When fish are near a boat, dolphins show signs to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins in doing so? They get to eat some of the fish.???
output answer:
Question: How do dolphins help fishermen catch fish?Options:A By playing with other fish.B By following fishing boats.C By leading the fish into the net.D By showing signs to the fishermen.Answer:D
