Read the following textbook passages. Then choosethe three inferences that are most logically based on the given facts in each passage.1George Washington’s honesty is a trait that has been well publicized. 2The famous story of how little George chopped down his father’s favorite cherry tree, then bravely admitted to the deed, has an honored place in American presidential history. 3The cherry tree story was first recorded in 1806 by Parson Mason Weems, a Maryland preacher and storyteller. 4Unfortunately, Parson Weems was none too honest himself, and it appears that he invented the story of George and the cherry tree. 5There is no record of the cherry tree incident anywhere until it appears in Weems’s book. 6The parson, it seems, thought it acceptable to teach the virtue of honesty through a made-up story. 7We can judge Weems’s own truthfulness by the fact that he describes himself in the book as “formerly rector of Mount Vernon Parish.” 8Such a parish never existed.
1The Chicago Tribune once wrote that Henry Ford, the founder of the Ford Motor Company, was an ignorant man.2Ford sued, challenging the paper to “prove it.”3During the trial, Ford was asked dozens of simple, general information questions: “When was the Civil War?” “Name the presidents of the United States,” and so on. 4Ford, who had little formal education, could answer very few. 5Finally, exasperated, he said, “I don’t know the answers to those questions, but I could find a man in five minutes who does. 6I use my brain to think, not store up a lot of useless facts.”
