Question: Write a multi-choice question for the following article, with the given choices and answer: Article: About this time every year, I get very nostalgic . Walking through my neighborhood on a fall afternoon reminds me of a time not too long ago when sounds of children filled the air, children playing games on a hill, and throwing leaves around in the street below. I was one of those children, carefree and happy. I live on a street that is only one block long. I have lived on the same street for sixteen years. I love my street. One side has six houses on it, and the other has only two houses, with a small hill in the middle and a huge cottonwood tree on one end. When I think of home, I think of my street. Only I see it as it was before. Unfortunately things change. One day, not long ago, I looked around and saw how different everything has become. Life on my street will never be the same because neighbors are quickly grown old, friends are growing up and leaving, and the city is planning to destroy my precious hill and sell the property to contractors. It is hard for me to accept that many of my wonderful neighbors are growing old and won't be around much longer. I have fond memories of the couple across the street, who sat together on their porch swing almost every evening, the widow next door who yelled at my brother and me for being too loud, and the crazy old man in a black suit who drove an old car. In contrast to those people, the people I see today are very old neighbors who have seen better days. The man in the black suit says he wants to die, and another neighbor just sold his house and moved into a nursing home. The lady who used to yell at us is too tired to bother any more, and the couple across the street rarely go out to their front porch these days. It is difficult to watch these precious people as they near the end of their lives because at once I thought they would live forever. The "comings and goings" of the younger generation of my street are now mostly "goings" as friends and peers move on. Once upon a time, my life and the lives of my peers revolved around home. The boundary of our world... Options: A removing the hill to make way for residential development B the building of new homes behind his kitchen window C the fact that there are much fewer people around than in the past D the change in his childhood friends' attitude towards their neighborhood Answer: A removing the hill to make way for residential development Question:
Answer: The biggest change on the writer's street is   _  .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Let's do some sleep math.You lost two hours of sleep every night last week because of a big project due on Friday.On Saturday and Sunday,you slept in,getting four extra hours.On Monday morning, you were feeling so bright-eyed that you only had one cup of coffee, instead of your usual two.But don't be cheated by your energy.You're still carrying around a heavy load of sleepiness, or what experts call"sleep debt"----in this case something like six hours,almost a full nights' sleep. Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get.It's a deficit that grows every time we skim some extra minutes off our nightly sleep."People accumulate sleep debt gradually without being noticed,"says William C.Dement,founder of the Stanford University Sleep Clinic.Studies show that such short--term sleep deprivation leads to a foggy brain,worsened vision,and trouble remembering. Long-term effects include obesity,insulin resistance, and heart disease. A survey by the National Sleep Foundation reports that we're losing one hour of sleep each night----more than two full weeks of sleep every year. The good news is that,like all debt, with some work,sleep debt can be repaid. Adding an extra hour or two of sleep a night is the way to catch up.For the long--term lack of sleep,take it easy for a few months to get back into a natural sleep pattern. Go to bed when you are tired,and allow your body to wake you in the morning(no alarm clock allowed).You may find yourself catatonic in the beginning of the recovery cycle:expect to have ten hours shut-eye per night. As the days pass, however,the amount of sleeping time will gradually decrease. So earn back that lost sleep----and follow the dictates of your innate sleep needs. You'll feel better."When you put away sleep debt, you become a superman,"says Stanford's Dement, talking about the improved mental and physical capabilities that come with being well rested. Options: A you can think and remember things clearly B you can still see everything very clearly C you can drive your car easily D you may have a poor sight Answer: D you may have a poor sight Question:
Answer:

assistant: If you have short--term sleep deprivation,_.
