input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: You've bought what you need. The grocery cashier asks, "Will that be paper or plastic? You reply "Plastic, please." This seems like a simple question and there are plenty of reasons we choose plastic: easier to carry, lighter than paper bags, possibly less damaging to the environment, less expensive to the shop owners, able to be used as trash bag, and so on. There are different opinions on plastic and paper. Now let's follow the travels of 3 plastic bags. It begins at the grocery store with the customer's choice. Plastic Bag 1: As the waste engineer come by and pick up the trash, the first plastic bag falls out. It sits on a small street for a couple of hours until a car comes along and takes it down to the road. Then a gust of wind blows it across the road, then another car, then another gust of wind finally makes its way to the beach. Water fills the plastic bag and makes it look like a jellyfish. A seal swims by, thinking it looks very interesting, and swallowed it. The plastic bag may stay in the seal's stomach for months, maybe years. You see, our lovely animals have been living thousands of years in a world where everything can be eaten. Plastic Bag 2: This bag does make its way to landfill . Before they have a chance to cover up the thousands of pounds of daily waste, a strong wind comes up and blows these plastic bags out of the landfill. Once the wind stops, workers will be sent to collect thousands of bags around. But they can't possibly get them all. So our little bag continues his adventure getting caught in trees, eaten by birds or making its way to our lakes or rivers. Plastic Bag 3: The last bag also blows away but is caught in a landfill where it sits for many years, as all the trash is wrapped in a big plastic bag, making natural degradation impossible. Although workers do much work to make sure water and air system won't be polluted, some do. Guess what, plastic bags are made from petrol, a harmful waste material, which in one way or another makes its way to the environment. Another... Options: A He can use plastic bags to carry trash later. B He finds paper bags heavier than plastic bags. C He finds plastic bags more convenient to carry. D He can save money for plastic bags are cheaper. Answer: D He can save money for plastic bags are cheaper. Question:

output: According to the passage, what is NOT the reason for a customer to choose plastic bags?

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: No budget for your vacation? Try home exchanges ---- swapping houses with strangers. Agree to use each other's cars, and you can save dollars on car rentals , too. Home exchanges are not new. At least one group, Intervac, has been facilitating such an arrangement since 1953. But trading online is gaining popularity these days, with several sites in operation, including Home Exchanges. Founded in 1992, with some 28,000 listings, this company bills itself as the world's largest home exchange club, reporting that membership has increased 30% this year. The annual fee is usually less than US$100. Members can access thousands of listings for apartments, villas, suburban homes and farms around the world. Initial contact is made via e-mail, with subsequent communication usually by phone. Before a match is made, potential swappers tend to discuss a lot. However, the concept may sound risky to some people. What about theft? Damage? These are reasonable causes for concern, but equally unlikely. As one swapper puts it, "Nobody is going to fly across the ocean or drive 600 miles to come steal your TV. Besides, at the same time they're staying in your home, you are staying in their home." Exchange sites recommend that swappers discuss such matters ahead of time. They may fill out an agreement spelling out who shoulders which responsibilities if a problem arises. It does not matter if the agreement would hold up in court, but it does give the exchangers a little satisfaction. Generally, the biggest complaint among home exchangers has to do with different standards of cleanliness. Swappers are supposed to make sure their home is in order before they depart, but one person's idea of "clean" may be more forgiving than another's. Some owners say if they come back to a less-than-sparkling kitchen, it may be inconvenient but would not sour them on future exchanges. Options: A By phone. B Via a matchmaker. C By e-mail. D Via a face-to-face meeting. Answer: C By e-mail. Question:

Answer: How do home exchangers normally begin their communication?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Entire populations of American toads breed within the same few days at the same time each year, usually late April or early May. The toads hop to their breeding ponds after the ground has warmed and the first hard spring rain falls. To get there, many of the toads will cross roads that cut through their habitat. It will be a grand view of hopping toads as well as a disastrous killing by cars! The toads are "slow in moving at that time of year--it's still cool, they've been inactive--and they get killed" by cars when crossing roads, said Serrao, a naturalist. An April night five years ago, when Serrao went out to a country road to watch the moving of the toads, he counted 100 toads; 95 were hit by cars. A similar story can be told for several other species of toads, frogs, crocodiles and turtles around the world. The world's amphibians are reducing, and road-killing is just one factor behind it. Other better-known causes of the decline include global warming, insecticides , and the loss of wetlands. Serrao says unless these animals get help crossing the road, their local populations will disappear. Jackson, a biologist, said one way to help amphibians survive road crossings is to construct "amphibian tunnels" beneath the road. Jackson says tunnels should be a 0.6-meter-by-0.6-meter box, open at the top, and fitted with an iron grate to allow enough air and light into the tunnel. In addition, fences or walls should extend out from either side of a tunnel for about 30 meters, which guide amphibians toward the tunnels. European countries have built amphibian tunnels for decades. Jackson led a team that installed the first such tunnel in prefix = st1 /Americain 1987, which helped over 3/4 of the local amphibian population safely cross the road. Jackson says that there are about a hundred amphibian tunnels in the UStoday, but many of them were not carefully designed and probably not working well because land developers wanted to save money. Options: A Before the ground is warm. B When the first heavy rain comes in spring. C After it is cool in sunny summer time. D When it is early April. Answer: B When the first heavy rain comes in spring. Question:???

When do American toads hop to breeding ponds?
