Loufrani's actions irked Ball, who felt that such a universal symbol should remain in the public domain in perpetuity. So in a pleasant proactive move, Ball declared in 1999 that the first Friday in October would be "World Smile Day" to promote general kindness and charity toward children in need. Ball died in 2001.

　　Questions 6-10

　　Good teachers matter. This may seem obvious to anyone who has a child in school or, for that matter, to anyone who has been a child in school. For a long time, though, researchers couldn't actually prove that teaching talent was important. But new research finally shows that teacher quality is a close cousin to student achievement: A great teacher can cram one-and-a-half grades' worth of learning into a single year, while laggards are lucky to accomplish half that much. Parents and kids, it seems, have been right all along to care whether they were assigned to Mrs. Smith or Mr. Brown.
