0	-1	Descriptive title that refers to the main point(s) in the report and is not the one from the manual. Plug in deduction as negative number.	✔
Purpose
	1	This can be a listing of several points, goals, and or claims. They should include both general and detailed purposes. Was the goal the answer to a scientific question, identification of a compound, or develop a technique or something else?	✔
	1	What will the final claim (conclusion) be? If you know the claim, it can clarify what the purpose was or should have been. (Normally you would start with the purpose and proceed toward the claim at the end)	✔
