Both reading and writing are about "burning mirror", which was a tool that Greeks used it against the Romans when they have been attacked by them. The passage states that Greeks of Syracuse never really made such a device. However, the professor rebus the author's reasons and thinks the Greeks certainly made this weapon .
First, the author of the article says that the technology for manufacturing burning mirror was too sophisticated for Greeks. On the other hand, listening talks about how the Greeks were absolutely able to make it by simply using single sheets and small coppers.
Second, using burning mirror was impractical for the Greek due to the long time that it requires to be prepared. The professor casts doubt on this point and mentions that it just takes a long time if the whole ship is made of wood, whereas, the ship was not only made of wood. Something called pitch, was used in the ship in order to attach different parts of the vehicle. This substance burns in a really short time and it can lead to easier use of burning mirror.
Third, according to the reading, there is no point in creating burning mirror due to it is equal to arrows, which are the weapons that they were already using. The professor challenges this idea when he mentions that burning mirror can surprise the enemies since it shoots from an invisible place for them. Therefor, it can be more effective than flaming arrows.
