I am amazed by how C so readily traps readers when it is factually wrong facepalm

I was deliberating on E but the "prevention" term really put me off, as there was no explicit correlation between exercise and the prevention of pain.

#help I can understand JY's explanation of D, but I hesistated on B since the stimulus stated France had no access to Cumberland graphite while the answer was about "any". If we go by B's logic then wouldn't it lead to the statement being "All solid graphite during the 1790s were mined in Cumberland?

I am!

#help I chose A but went for E on blind review. Can someone tell me why E is wrong?

I narrowed it between C and D and chose C both because it introduced a new possibility for the conclusion. "Well, what IF there were other minerals that interfered?" While C didn't make sense from instinct "there aren't only three components in dust" it fit much more with I've been taught.

D however, directly attacks the conclusion instead of support which drove me away twice. I am so confused, where did I go wrong? #help

I immediately understood why AC E was correct choice. FFS it was in the first sentence. Don't ignore the context! !

Me!
