▶ Your Answer :
According to the reading
passage, about 70 forts are built with vitrified stones throughout Scotland and
the origin of these forts is explained by fires, lightning, and volcanic rocks.
The lecturer opposes the reading passage’s claim by providing three reasons.
First, the lecturer argues
that vitrification is not caused by signal fires. Although fires can melt the
rock over time, there were only one or two fires along the long wall and the
position of the fire did not change over time. However, forts with vitrified
stones were scattered throughout Scotland. This contradicts the reading passage’s argue that signal
fires caused vitrification. (GOOD)
Second, the lecturer asserts
that lightning cannot explain the cause of vitrification. Structure of the
existing vitrified stone is very large and extensive, and lightning cannot
cover the whole place. Moreover, cracked rocks exist not because the lightning
occurred but they were old enough to be cracked. This counters the reading
passage’s claim that
lightning made vitrified stones.
Lastly, the lecturer points
out that the lava from volcanic eruptions is not the cause of building vitrified
rocks. At past, there was no volcanic activities near the region. It meant the
ancient residents had to carry vitrified stones along the vast distance, but
they did not have local material to make equipment. This casts doubt on the
reading passage’s claim that lava
processed vitrification.
