Given the question: I'm taking a test and have to guess the right answer to the question after the article. Article: "Hey, don't read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. Don't read in dim light! This is one of the "pearls of wisdom" that are supposed to help us live a healthy life.
