Another way to(16)nuclear waste is to send it into space, to the sun,(17)it would be burned. Other scientists suggest that this polluting material be(18)thousands of meters under the earth’s surface. Such underground areas must be free(19)possible earthquakes. Advances are being made. But it may still be many years(20)this problem could be finally settled. 1.
