[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: You're on the school bus. But as soon as you turn the corner, you find yourself at the end of a very long queue. It's another _ ! It is stop-start for the rest of your journey. Meanwhile, at the same time in Antarctica , snow covers the land. A group of emperor penguins crowd together to keep warm, using stop-and-go movements to protect themselves from the winds. Can you see the connection? Emperor penguins move like cars in traffic jams to keep warm, that's according to new research by the Alfred Wegener Institute, Helmholtz Center for Polar and Marina Research in Germany. A penguin only needs to move 2cm in any direction for its neighbor to do the same thing. These movements then flow through the whole group of penguins like a "traveling wave". These waves also help smaller crowds join bigger groups, keeping more and more of their friends warm. A single Antarctic "traffic jam" has thousands of penguins. Interestingly, the technology used for studying road traffic jams was used to study the penguins. This included studying time-lapse videos. Scientists also discovered that unlike on the road, these waves can be made by any penguin and in any direction. With temperatures usually dropping below -50degC, and winds reaching speeds of up to 200km/h, these traveling waves are very important for penguins to keep warm. These penguins can also teach us a lesson. In big groups, they learn to be orderly and patient, and to never crash into each other. These are skills we should all learn from them when we are on the road! Options: A needs to move orderly B can move as fast as it likes C will not leave others behind D should move as slowly as it can Answer: A needs to move orderly Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Nowadays, many children spend hours a day looking at computer screens or other digital products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome . Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. "More children come into my office because their parents have noticed that they have headaches or red eyes, or because their degree of short-sightedness appears to be increasing very fast and they're worried," he said. Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don't tell their parents, because they don't want their games or the computer to be taken away. Another part of the problem is that people blink less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally do in everyday life. If eyes can't stay wet or are too tired, they will not be protected like normal. Options: A They think it is not serious. B They want to continue playing computer games. C They don't want their parents to worry. D Their parents don't care about them. Answer: B They want to continue playing computer games. Question:
