Eva has made the claim in her argumentative essay that a trip visiting national parks is the best summer vacation. Which is the best example of a counterclaim to this argument? National parks are protected areas with unique geology and unusual natural beauty. Some might argue that the Grand Canyon is the most beautiful of the fifty -nine national parks. Yellowstone National Park is known for many geysers particularly the amazing Old Faithful. Some might argue that a trip to historical monuments is a more educational summer vacation
