D)introduce and provide context for each quotation
A floating quotation occurs when there is no clear connection from the original writing to the quotation. For example: I love my dog. "97% of dog owners love their pets." She is a great dog. This quotation has no information that ties it to the rest of the sentences. There should never be a period before opening quotation marks. To fix this, the author must introduce the source and provide context. For example: I love my dog. According to Anony Mous from <em>Made Up, </em>"97% of dog owners love their pets." Now if you're quote is more sophisticated than mine, you may need more information. For example: Before Johnny died in <em>The Outsiders</em> he gave Ponyboy one last piece of advice, he said, "Stay Gold." This tells us who is speaking and what is happening when he says the line.
Before things like mountains were typically boundaries since they were a pain in the butt to cross. But with modern planes, and depending on the mountian, cars, mountains aren't as big a pain anymore. Deserts might have also been a boundary before. Today you turn on the AC and drive straight across it. At least for technologically advanced western countries, there really isn't any geographic feature we can't easily get around.
