Both the lecturer and the reading passage discuss buildings in Scotland (vitrification에 대한 입장 차이일 경우 좀 더 specific하게 그들이 논하는 주제가 어떤 것인지 define 해 주세요) The lecturer casts doubt on the author's claim on several reasons on the cause of the vitrification of stone that are used for buildings are vitrified, by presenting three counter arguments.
First, the lecturer claims that vitrification caused by signal fires along the walls is not confirmed. This is because signifiers were only on the walls of few areas. As the entire walls show vitrified stones, the use of signifiers would be disputable. This refutes the author's claim that vitrification is caused by signal fires that melted the rock over time.
Second, the lecturer claims that lighting as a plausible explanation for vitrification is controversial. This is because dozens of lightening would be required to transform rock into a glass-like substance. However, changes of lightening strike at the same place is very unlikely to be found. This counters the author's assertion that lightening strike would have caused stones to be vitrified.
Lastly, the lecturer contends that using volcanic rocks that are vitrified already is disputable. Volcanic rocks should be exposed to lava. However, there are no past evidences of volcanic eruption near these regions, and it is very difficult to move these heavy rocks around. This opposes the author's assertion that volcanic eruptions caused vitrification of the rocks.
