Take the following as truth: While service standards differ (many countries offer two mail deliveries each weekday, for example), even at 33 cents, U.S. prices compare favorably with first-class rates overseas--Japan charges 74 cents, Germany 59 cents, France 48 cents, and Great Britain 37 cents.
Then the following statement: "Service standards differ and US prices are much lower than all other countries." is true, false, or inconclusive?
Answer: Inconclusive
