Exercise 4.4

Now we combine the two passages, and produce an argument map of the whole chain of reasoning:

Hoax believers object to the claim that the Apollo astronauts landed on the Moon, on the grounds that the tyres of the Lunar Roving Vehicle would be likely to explode in the vacuum of space. However the tyres were not of the traditional inflated rubber variety. The purpose-built LRV tyres were actually made from a mesh of zinc-coated piano wire, to which titanium treads were riveted in a chevron pattern. [Based on 8.5]

Note that for this exercise you need not diagram hidden premises.
