The reading provides three reasons to show that burning mirror is a myth and the Greeks of the Syracuse could not have such a weapon. The speaker, however, said that the reasons are unconvincing and refute each reason by indicating following points.
First, the passage says ancient Greeks were not advanced technologically enough to build such a large complex mirror. But the speaker states that they did not have to build such a large mirror and several smaller mirrors can mimic the same purpose. She explains that the same parabolic curvature is achievable through some help from a mathematician.
Second, the author states that it takes a long time to set wood on fire at that distance according to their experiment and that was without considering the ships are on the move. However, the speaker reminds that the ships' construction material is not just include wood. She explains that there is a sticky material called pitch that were used to waterproofing the ships and this material can catch fire in a matter of seconds.
Third, the author claims that burning mirror was not an improvement over their framing arrow at the time and hence they had no intention to built such a weapon. The speaker objects this reason by saying that the Roman navy was aware of the flaming arrow and would notice the weapon as soon as the Greeks wanted to use them while burning mirror could set their ships on fire without attracting their attention. So, the Romans would not notice until their ship is actually on fire.
