Directions: Read the short paragraph carefully. Look and encircle for signal words that show problem-solution.Then,answer the question that follow . Astronauts face many challenges in space caused by weightlessness. One of these obstacles is floating around the cabin. To solve this problem, astronauts wear shoes that are coated with a special adhesive. This adhesive sticks to the floor of the cabin. Serving food is another problem. It will not stay put on the table! Experts overcame this problem by putting food and drinks in pouches and tubes. It only needs to be mixed with water. Weightlessness also causes problems when an astronaut tries to work. The simple task of turning a wrench or a doorknob can be difficult. Since there is no gravity to keep him down, when he exerts a force in one direction, the opposite force may flip him over completely. To solve his problem, he must be very careful about how much force he uses to do these simple tasks. Here on earth, life is much simpler, thanks to gravity. 1.
