Using What You Learned in Chapter 3, Write an Essay

Essay

Using what you learned in Chapter 3, write an essay explaining any difficulty in the following piece of reasoning:
"Look, if one television set has one more line of resolution than another, you can't say the first is 'highdefinition TV' and the second one is not. So whether a set has 900 lines or 901 can't make the difference. Neither can the difference between 1800 lines and 1801 lines. In fact, there's no place where you can identify exactly where definition becomes 'high.' So there's no point in talking about high definition, when you get down to it."
