TPO-30 - Integrated Writing Task A little over 2,200 years ago, the Roman navy attacked the Greek port city of Syracuse. According to some ancient historians, the Greeks defended themselves with an ingenious weapon called a "burning mirror": a polished co

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 a 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 igniting wood using the mirror is time-consuming, the lecturer points out that the pitch on ships can caught fire in seconds and subsequently spread fire to wood, 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 its working 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.
