Exercise 3.2 Model Answer

Produce an argument map of the reasoning in this passage:

With the Moon's gravity being just 1/6th of the Earth's, one might expect dust on the Moon to fall more slowly than it does on Earth.  However, the Moon has no atmosphere to speak of, and so the dust would actually fall more quickly than on Earth. [Based on 4.3]

Note that for this exercise your argument map need not represent any hidden co-premises.

Model Answer


This multi-reason argument is a dispute - there is evidence both for and against the conclusion.
