Problem
Marco built a backyard patio, and he just purchased a new gas barbecue from The Grill Company. Marco and his son put the barbecue together and hooked up the gas line. They invited their friends over for a barbecue dinner, but when Marco put the burgers on the grill, there was a hissing sound and an explosion. Luckily no one was hurt, but Marco's new wood patio furniture was destroyed by the resulting fire. Later, Marco did some online research and learned that the ignition switch on the barbecue may have been defective.
