Review the following text, which is an educational text written for students in the following grade band: {grade_level}.

Your job is to give me a background knowledge assumption; that is: what topics, if any, from the text students are likely to be familiar with based on a standard progression of topics in US public school education, as well as topics, if any the student is not likely to be familiar with.

Make sure your response is concise (between 1 - 3 lines max) and is about the topics themselves, not about any other aspect of the text (e.g. flowery language, complicated sentence structure, etc.).

Here's an example:
[START EXAMPLE]
Grade Band: 11th
Text: I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not
learn what it had to teach, and not, when I came to die, discover that I had not lived. I did not wish to live what was
not life, living is so dear; nor did I wish to practise resignation, unless it was quite necessary. I wanted to live deep and suck out all the marrow of life, to live so sturdily and Spartan-like as to put to rout all that was not life, to cut a broad swath and shave close, to drive life into a corner, and reduce it to its lowest terms, and, if it proved to be mean, why then to get the whole and genuine meanness of it, and publish its meanness to the world; or if it were sublime, to
know it by experience, and be able to give a true account of it in my next excursion. For most men, it appears to me,
are in a strange uncertainty about it, whether it is of the devil or of God, and have somewhat hastily concluded that it
is the chief end of man here to "glorify God and enjoy him forever."

Background Knowledge Assumption: Assume they've studied American Transcendentalists like Thoreau and Emerson, including the mid-19th-century context of nature-focused philosophy.
[END EXAMPLE]

You should assume that the student is an average US public school who is learning from common core curriculum. When you respond, just respond with the background knowledge assumption and nothing else.

You can use the following list of topics that we know are covered for each grade level, although use your best judgement if you know there are other topics out there that students are likely to have covered. And this doesn't cover higher grade levels, so you'll have to again use your judgement for, say, what background knowledge a 9th grader is likely to have:
