Logic Breakdown

Passage Summary: In the 1790s, France couldn't get the solid graphite they needed for pencils from Britain because they were at war, so they researched and invented a way to make leads from powdered graphite instead.

Reasoning: Early pencil leads required solid graphite from Britain; France was at war with Britain in the 1790s and lost access to that graphite; consequently, France funded research that led to modern powdered graphite leads.

Analysis: For this 'Most Strongly Supported' task, we must treat the statements as facts and see what they imply when combined. The stimulus sets up a clear cause-and-effect relationship: a lack of access to a specific raw material due to war led to the development of a new technology. Look for an answer choice that reflects this historical necessity. We are not looking for a bold claim, but rather a modest synthesis of how the war influenced French pencil manufacturing.

The information above most strongly supports which one of the following?

Correct Answer
B
If France had access to any suitable, accessible solid graphite source in the 1790s, it would not need to fund research to create pencil leads from powdered graphite. The fact that war cut off access to Cumberland and prompted the research strongly supports that France did not know of any accessible source of appropriate solid graphite at that time.
