In the lecture, the professor discussed why the arguments mentioned in the reading passage on the impossibilities of building the "burning mirror" is not plausible.
To begin with, the passage claims that the size of an powerful mirror would be enormous and the shape has to be precise, and the technology then was not sufficient. However, the speaker refutes this by saying that mathematicians in Greek were able to construct the parabola-shaped mirror using small pieces of flat copper.
Secondly, whilst the reading material asserts that experiments proved that it is time-consuming to ignite wood using the mirror, the lecturer points out that pitch used when building the ships can caught fire in seconds, thus the mirror is highly likely to be effective enough.
Finally, the professor states that although the Roman navy was familiar with flaming arrows and could defend against them, they would be astounded by a "burning mirror", which looks not assaultive. By doing so, the "burning mirror" is much more effective, despite the its effective distance is not considerably longer than the flaming arrows.
In conclusion, based on the reasons and analysis provided by the speaker, the theories in the passage that the "burning mirror" is difficult to build, it works slow on wood and not advanced compared to flaming arrows do not stand.
