Jesse Jesse Was Playing with Marbles When One of the Marbles

Multiple Choice

Jesse
Jesse was playing with marbles when one of the marbles fell into a heating vent in the floor. Jesse could see the marble, but he couldn't reach it because the slats of the vent were too close together for his hand, and he couldn't remove the lid. Jesse said, rather sarcastically to himself, "Well, that's just fabulous." He looked around the room for something that he could use to retrieve the marble. When he saw his juice glass with the straw in it, he got an idea. He took the straw, carefully lowered it into the vent until it touched the marble. Then he sucked on the straw so that it "grabbed" the marble as he gently raised it back up into his waiting hand. Quite pleased with himself, and a little dizzy, Jesse went back to playing marbles.
