Write a multi-choice question for the following article, with the given choices and answer: Article: It was a long process that involved creating a resume, submitting an online application and attending a round of interviews. Naturally Tan Kaiyin, a 21-year-old student is excited when she was selected, as more than 660, 000 people signed up to volunteer at the 16thAsian Games in Guangzhou, but only less than 10 percent were finally chosen to work in the venues and wear the white and green sport uniforms.

She is based at the Garden Hotel and is tasked with helping guests and officials who have issues with their accreditation cards . "I deal with guests from all over the world, I have never met so many international people and it is very, very exciting to have this opportunity to interact with them. They come to the office because they need to make a change in their accreditation card and usually they are in a hurry, so we try our best to get it done quickly." She admits the first few days involved extremely long hours, however she likes the challenge as it gives her an immense sense of satisfaction especially when an irate guest turns a frown into a smile and says "thank you".

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Energy goes from one plant or animal to another. A food chain shows how this energy moves. Each time an animal gets eaten, its energy is passed onto the animal that eats it. The food chain is very important because it keeps the balance of nature. If one part of the food chain disappears, it can affect all the other plants and animals. Any threat to the food chain is a threat to the environment's biodiversit . The food chain helps keep animal populations in balance. However, if something happens to increase or decrease one of the links in the food chain, that balance is broken. If one animal becomes endangered, it puts all the animals above it at risk. Some of the threats are natural, such as wildfires, hurricanes, tornados, floods and so on. But the biggest threats to the food chain come from you and me. These threats include overhunting, overfishing, logging, farming, development, pollution, etc. The food chain is endangered anywhere humans have had an effect on the natural environment. A recent study shows that the overfishing of large sharks is damaging the food chain along the US Atlantic coast. Canadian and American scientists say sharks are being killed in great numbers for their meat and fins . Now, not enough sharks are around to eat the cownose ray. The ray's population has increased and they have eaten up the shellfish to the point where it has hurt commercial fishing. Many of us disturb the natural environment in our own backyards. It's up to us to take care of the environment and try not to disrupt the natural food chain. If we don't act responsibly, animals will start disappearing. Options: A explain what the food chain is B tell us something interesting about Nature C suggest that we stop eating meat to save animals D suggest that we not disrupt the natural food chain Answer: D suggest that we not disrupt the natural food chain Question:
A: We can infer that the writer wrote this passage mainly to _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: A British dog-lover has invented a high-tech way of feeding his pet by Twitter( ,). Computer expert Nat Morris ,30, has designed a system to give his pet a "tweet treat" by sending him a Twitter message. His dog Toby gets some delicious dog biscuits from a computer-controlled food machine whenever Nat sends a message to "@ feedtoby". Nat often works away from home and isn't always able to feed Toby by hand. But his new invention allows Nat to feed his dog from anywhere in the world. Nat said, "Toby ly loves it. At first he didn't know what was going on. Now he sits underneath the machine, wagging his tail and waiting for the food to drop." Nat fills the food machine with small pieces of dog biscuits, but not too many in case four-year-old Toby gets too many messages. And Nat has even equipped his house with an online camera so he can see Toby enjoying the food at his home. But one problem is that friends and family have been so amazed with the "tweet treat" machine that they have started sending tweets to Toby too. So Nat has had to restrict feeding time to make sure Toby doesn't turn into Tubby. "People have been sending him tweets at all hours of the day, so I had to limit it to between 9a.m. and 9 p.m. . I'm thinking of doing an updated one which can measure his weight before he is fed, just to make sure he's not putting on too much puppy fat," explained Nat. How Nat's Twitter Feeder works: When a message is sent to @ feedtoby, it is received by a mini -computer that is linked to the feed machine. When the mini-computer receives the message, a bell rings and Toby comes running over and sits in front of the feeding machine. Next, the machine's motor pulls open a trap door which releases a serving of food. The doggy biscuits then drop into Toby's food bowl. Finally a digital camera takes a photo of him and sends it back to Nat on Twitter -- so he knows Toby has been fed. Options: A wants his friends to feed Toby B has very strong computing skills C is often too busy to feed his dog D doesn't like to feed Toby by hand. Answer: C is often too busy to feed his dog Question:

Nat has invented a high-tech way to feed his dog because he _ .
