The article states three theories of why Greeks had never created a burning mirror weapon to defend themselves. However, the speaker disagrees with each of the theories provided in the passage.
First, the reading posits that Greeks were not advanced in technology to create a device. However, the professor opposes this point by saying that the experiment has shown that ancient Greeks could have arranged dozens of pieces of polished copper into parabola shape to make large copper sheet. Greek mathematicians knew the properties of mirror to make a weapon effectively.
Second, the article claims that burning mirror might take long time to set fire on ships. However, the speaker counters this idea by saying that Romans' boats were not just made from wood, but there were other sticky materials, such as pitch. It was used as water proof substance to fill gaps between sides and also to catch fire quickly. So, Romans could fire within seconds and also when ship is moving.
Third, the reading asserts that flaming arrows were mostly used by ancient Greeks. However, the professor contends that Romans knew that flaming arrows were ineffective because it could be easily seen by enemies. On the other hand, burning rays can't see from mirror. So, burning mirror was effective to set fire on ships without even seen by anyone.
