Why B?
Hi I was wondering why it's B. Because when I read the passage I thought I couldn't make such an inference whereas E seemed like the correct answer because regardless we have graphite's in the pencils.

This is a most strongly supported question, meaning that the answer doesn't have to be undeniably true, but the one that can be most reasonably inferred from the stimulus.
Answer choice B provides that, at this time, France had no accessible alternative to solid graphite. This would reasonably support why France conducted their own research in order to supply their need for solid graphite for usage in pencils. Otherwise, it would be much simpler to access an already available source of solid graphite.
Answer choice E is incorrect because it says all. There is no way to prove or support that absolutely all pencils today use graphite mined in Cumberland. Perhaps there is another or many other sources of graphite for pencil lead available today.
Hope this helps!

I thought B was trying to trick us up by using "1790s" instead of "1970s." I figured it would be the perfect answer if it had said "1970s" but thought there was no way to know based on the information in the prompt whether or not the French knew of a better graphite deposit that many years before the 1970s.

Oh dear, I believe this is a typo. I've added this to the devs queue.
