One point is just for context - if you can locate the issue within its broader historical situation. You do need to write several sentences to a paragraph about it, but don’t stress; all you really need to know to be able to get this point is information about major historical trends over time, and you will need to know this anyways for the multiple choice section. If the question is about the Dust Bowl during the Great Depression, for example, be sure to include some of the general information you know about the Great Depression! Boom. Contextualized.
