Although the reading proposes three theories to explain the use of Scotland brochs, the listening believes that the brochs' purpose remains mysterious and each of the theories suggested by the author is problematic.
Primarily, in contradiction to the passage's argument, the lecture contends that brochs are not built for defensive purpose. The major problem is that brochs have no windows whereas most forts have small windows. Windows play an important role in letting the defenders to shoot arrows and thus keeping the attackers at certain distance so that they cannot come close to the structure. Without windows, attackers could easily set brochs on fire or break down its doors.
Further, the professor denies the author's theory of grain storage as well. First, there are large water tanks in brochs, which would release moisture into the air and cause grain to rot. Second, some brochs also contain fireplaces. Dust from the grain could catch fire and cause explosion if these fireplaces had been placed near grain storage.
Finally, while the reading says that brochs could be homes for chieftains, the listening points out that their locations indicate that it is unlikely. In ancient cultures, it is typical for a leader with one large home to live near many other smaller homes in which everyone else live. However, it is found that some brochs are totally isolated or that many of them group together. It is impossible for leaders to live alone far away from villagers or many leaders live together.
