In "Volume VI - Experiments » Basic Concepts And Test Equipment » Ohmmeter usage," I found the following sentence:

"The less resistance there is between two points, the harder it is for electrons to move (flow) between those two points."

It is in the 6th paragraph after the illustration of an ohmmeter measuring a resistor. I believe the sentence should say either "less resistance... easier" or "more resistance... harder."

 

I agree that there is an error. Given the context of the next sentence, it would probably be better to change it to "more resistance", but either will work.
