▶ Your Answer :
In the lecture, the
speaker maintains that the theories suggested in the reading are not
groundless. This casts doubt on
the reading passage’s point that there are practical theories to explain why petroglyphs
were made.
To begin with, he
asserts that petroglyphs did not function as communication tools. This is
because if tribes that were in hostile relationships with nearby tribes made
petroglyphs, they would have been informed by petroglyphs about their local
geography. This opposes the
reading’s point that the carving were made by different about tribes to help
each other.
On top of that, the
lecturer argues that petroglyphs were not made for religious rites. The reason
is that other creations made for religious rituals, such as carve painting, were
detailed and elaborate. However, petroglyphs were crudely made. Therefore, ancient
people would not have carved for religious rituals. This contradicts the
reading passage’s claim that petroglyphs were carved for religious rites.
Finally, the speaker
contends that carvings were not created to escape boredom. This is because recreation
of ancient people were practical. For example, boys played war games to improve
their hunting skills. This refutes the
reading’s point that to kill time, ancient people made carvings.
