The professor actually contradicts the statements made in the passage. She is of the view that the Greeks of Syrasuse defended themselves with the weapon called "burning mirror".
First of all, the reading passage presents the fact that the ancient Greeks had no such advanced technology to build a enough widely mirror to focus sunlight in order to set Roman ships on fire. However, the speaker casts doubt with the arguments that the ancient Greeks have not need to make a large mirror, they could focus sunlight with many small mirrors.
Secondly, the reading material displays the evidence that it takes time to set wood ships which have to stay in their position on fire and the Roman ships will never do that, they will move. In contrast, the lecturer in the listening argues that the materials are used to build ships by Roman is not the wood which catches fire very quickly.
Finally, the author of the reading states that the flaming arrows would have the same effective as "burning mirror", so it is not necessary for Greeks to build a new weapon. On the contrary, the listening rebuts that statement by pointing out that Roman navy is familiar with flaming arrows, but if Greeks use the mirror for causing Roman ships to catch fire, Roman navy will be very surprise and have no prevention in advance.
