What Grade Would You Give This (ASAP)?

C. Morse is not a noun, it's a proper name used here as an adjective. Your definition is of a grimace (a noun, singular), but your example uses it as an adjective. Your bear example uses a different meaning for the word. And so on. Then I'd likely deduct half a grade level for improper capitalization. Sorry, you asked a person with respect for the English language.
