I'm taking a test and have to guess the right answer to the question after the article. Article: A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months. The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue. Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel. A sensor in the wristband detects this pressing action and measures the time between the sound the driver's response. Tiredness is directly related to a driver's response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy. In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver's response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible. The device has been delivered to the department's laboratories for testing. If these tests, scheduled for six months' time, are successful, the makers will bring the product to market within about a year. Question: According to the text, Driver Alert _ . Options: A: aims to reduce tiredness-related accidents B: has gone through testing at laboratories C: aims to prevent drivers from sleeping D: has been on sale for 12 months

I'm taking a test and have to guess the right answer to the question after the article. Article: Ben lived in the same house as I did, on the same floor, his door facing mine; we often saw each other, and I knew how he lived when he was at home. And at home it was the same story: dressing-gown, nightcap, closed windows, locked doors, and -'Oh, I hope nothing bad will happen!' Vegetarian food is not good for him, yet he could not eat meat, so he ate freshwater fish with butter--not a vegetarian dish, yet one could not say that it was meat. He did not keep a female servant for fear people might think evil of him, but had as cook an old man of sixty, called Alan, who had once been an officer's servant and could cook after a fashion. This Alan was usually standing at the door with his arms folded; with a deep sigh, he would _ always the same thing: "there are plenty of them about nowadays!" Question: What is the relationship between Ben and Alan? Options: A: Teacher and student. B: Friends. C: Family. D: Employer and employee

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Nature is full of color, from rainbows and roses to butterfly wings and peacock tails. Even the fruits and vegetables you eat have different colors: blue blueberries, red strawberries, green broccoli, and orange carrots. Plant and animals often use color to attract attention. The substances responsible for these colors belong to a class of chemical called antioxidants . Plants make antioxidant to protect themselves from the sun's ultraviolet(UV) light. Ultraviolet light causes chemicals called free radicals to form within plant cells. They can destroy parts of plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled skin can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals. Our bodies have natural defences for fighting off free radicals. While we are young, our defences are pretty strong. However, they get weaker as we get older. The body's built-in defences can only go so far without extra help. The key to fighting free radicals with fruits and vegetables is to mix and match colors. It's like sunscreen for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else. Research into how chemicals in blueberries affect the brain's function in rats suggests that these chemicals may help our own brains work more efficiently. Don't just blame the sun. Ultraviolet light isn't the only source of free radicals. If you breathe polluted air such as smog, automobile exhaust , or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food. Question: Which of the following can not cause free radicals to form? Options: A: Colorful food B: UV light from the sun C: Polluted air D: The body itself
A: A
