In this set of materials, the author of the reading passage expresses three hypotheses of burning mirror is just a myth and the Greeks of Syracuse never really built such a divice in 220 years ago. However, the professor thinks that the author's theories contain some defects.
First of all, the author states that ancient Greeks were not technongically advanced enough to make such a divice. On the contrary, the professor indicates that ancient Greeks did not build the mirror from single sheet into parabola. From the experiments, ancient Greeks may build the parabola from donzens pieces of coppers. Hence, small pieces form into large mirro.
In addition, the author claims that the burning mirror would have taken a long time to set the ships on fire. However, the professor asserts that according the author's reason, the author assumes that the ancient boat made from wooden. That is the reason that setting the boat on fire takes 10 minutes. In the fact, the Roman ships made from other materials such as pitch which is some kind of waterproof material. This material will be set on fire in second.
Finally, the author raises the point that the ancient Greeks already had the flaming arrows, it seems reluctant have both burning mirror and flaming arrows. On the other hand, the professor refutes the author's idea by saying that enemies was familiar with flaming arrows, and they will put off the fire. Hence, enemies had have never seen the mirros before, it would surprising enemies because they could not observe the mirror.
