Article: North American black bears are shy animals. They are fearful by nature, and will usuallyrun away if they see or hear people. Because of this, it can be difficult for scientists to learnabout these animals. In order to study black bears, researchers from New Jersey, USA, catch bears and usedrugs to help them go to sleep. Researchers then work out the size and the weight of the bear,take blood to test for diseases, _ a tooth and take it to the lab to find out its age. Fromthese studies, researchers want to find out how many bears live in New Jersey, how long theylive, and how many babies they produce. But in Minnesota, USA, researchers study bears that are completely awake. The bears knowthe researchers' voices and they are not afraid of die research team. With the help of a few grapes to keep the bears busy, researchers can touch them to check their hearts, look at their teeth, and do other jobs.Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives. In both places, the main purpose is the same--to make sure there is a healthy population of black bears. But theresearch methods and the kinds of information that researchers, are able to collect are quite different. Question: What do the two studies have in common?

Article: Smartphones, poor sight Look around and you'll see people busy on their smartphones. Smartphones do make our lives easier . But have you ever thought about what they mean to your eyes? According to a study, half of British people own smartphones and they spend an average of two hours a day using them. There has been a 35% increase in the number of people in the UK who suffer from shortsightedness since smartphones were introduced there in 1997. Staring at smartphones for long time gives you dry eyes. When looking at something in the distance, your eyes automatically blink a certain number of times. However, when you look at things closer to your face, the blinking slows down. This reduces the amount of tears and causes discomfort in your eyes. Another bad habit is using smartphones in dark rooms before going to sleep. If you look at a bright screen while your pupils become larger, too much light enters your eyes. This can do harm to the eyes and cause a disease called glaucoma . While you're probably not going to stop using to your _ , there are a few things you can do to protect your eyes. Hold your phone at least 30 centimeters away from your eyes when using it. Take a break every hour and try the following: look at something at least five meters from you and then focus on the tip of your nose. Repeat this several times. It should reduce the discomfort in your eyes. Question: This article is written to advise people _ . Yes or no, is the answer "to use smart phones properly"?
