A smart cat
My Snowball is a wonderful cat. I don’t know of any other cat that loves to watch Sesame Street. He will also come running up to the TV if he ___HEARS___ a baby crying or little kids playing. He can’t stand TV commercials! Anytime a commercial comes on he turns his head to the side and so he ___DOES_NOT_HAVE___ to watch the commercial. When the show is back on the air, he will start watching the show again. It was then that I ___FOUND___ out that when a commercial is on, the volume goes up a bit, and this is his signal to turn away. When the volume goes down then the commercial is over. Smart cat, I started to do the same thing.
Percy Spencer was an American physicist and inventor. He was the chief of the power tube division of the Raytheon Company. Once he noticed that microwaves from the radar set he ___WAS_WORKING___ on had melted the candy bar in his pocket. It had been known that microwaves generate heat. But he was the ___FIRST___ one to think of using this heat to cook food. He received a patent in 1950, and Raytheon developed the idea ___FURTHER___ for commercial and industrial use. In a sign of things to come, popcorn was what Spencer and ___HIS___ colleagues cooked with microwaves. Spencer’s creative thinking turned a routine observation into a technological breakthrough.
