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 copper surface curved to focus the Sun s

The reading passage and the lecture discuss about the burning mirror constructed by the Greeks. Despite that, the professor thinks that the reasons suspecting the burning mirror is not practical and unconvincing. She casts doubt on every single point the reading make and provide details to support her idea.

To begin with, the writer claims that the ancient Greeks did not have technology to build advanced device. However, the lecturer argues that the Greeks could use small and individual pieces to form a large flat mirrors. As a result, she can not give a nod to the author in terms of the first point.

Secondly, about how long it is required to set the ships on fire, the reading suggests it took ten minutes whereas the speaker disagrees this thought. She thinks that the ship was also made with other materials such as sticky pitch. It was easy to get on fire in a second. Moreover, the fire could spread to the wood even when on moving ships. Apparently, the lecturer disproves its counterpart in the reading.

In addition, the author indicates that the Greeks already had flaming arrows so they were not required to build a similar weapon such as burning mirrors. The professor, on the other hand, points out because the Roman were familiar with flaming arrows, the burning mirror could be an unexpected weapon and would be more effective than flaming arrows. Therefore, she reckon the third point is not convincing.

To sum up, the writer and the lecturer hold conflicting views. It is obvious that they will have difficulties finding common ground on this topic.
