2 basic questions over logical reasoning.

Hi everyone! I have 2 questions.

1st. In logical reasoning, when the question stem asks for the main point, is that slightly different then it asking for the conclusion? I watched an explanation video for a main point, the question stem said “Which one of the following states the main point of the argument?” And JY said that the main point questions are looking for a summary of the conclusion. Rather, I notice when the question stem ask for us to state the conclusion it will be a more “word-for-word” explicit answer, leaning away from a summary type answer. Is this correct? Or does it depend on other factors?

2nd. Okay. Another question. Is not always the same as sometimes in logic?

Thank you so much.

I look forward to the #help!

    1. There is a slight difference, but I would say it's negligible. So I'd definitely treat them the same. The main point is synonymous with the conclusion; a conclusion is just a claim you are trying to prove via the support from the premises. In other words, it is the main point you are trying to convey in an argument. So yeah, try not to get too hung up on the semantics, as logically, you are being asked to perform the same task.

    2. The function of "not always" serves to deny the truth of a universal claim. In other words, if we said its not always the case that all apples are bananas (A --> B), that would equate to the statement that there exists at least one apple which is not a banana, or A some /B . So to answer your question, not always (or not all) should be interpreted as at least one is not or some are not.
