Summarize the points made in the lecture, being sure to explain how they oppose specific points made in the reading passage.

The reading and the lecture are both about earthquakes and the reliability of different ways to predict this geological phenomenon. Whereas the author of the reading states that it is possible to forecast earthquakes occurrence by using several approaches, the professor casts doubt on the main points made in the reading by providing three main reasons. First of all, according to the reading, animal behavior is one of the ways to predict earthquakes. The author of the reading claims that some sensory abilities of animals are useful to make an early detection of changes in the environment, for instance changes related to earthquakes. However, the lecture disputes this point by asserting that is not true and there is no clear evidence on that. He argues that animals reactions are related to the shaking and movement that earth is experiencing, as animals can not detect an earthquake before it happens. Secondly, the reading states that people's headaches can be used as an indicator of an inminent earthquake, due to the presence of magnetite inside human brain. The author of the reading argues that magnetite inside the human brain makes possible realize changes in electromagnetic fields caused by earthquakes. Nevertheless, the lecturer refutes this point by saying that headaches are not realiable, due to people can experiment this condition due to stressful situations during an earthquake. On the other hand, the instructor affirms that magnetite content inside human brain is very low. Third, the reading claims that a radon emission measurement is a practical way to forecast an earthquake, as when a seismic event occurs rocks it releases radon to the athmosphere. Nonetheless, the lecturer believes that measurements of radon are not a such practical strategy because not only earthquakes trigger radon release from the rock, but also landslides and other conditions that exert an influence on rock fragmentation. The professor strongly argues that radon measurements can cause a false alarm of earthquakes. In summary, although the reading and the lecture are both about a discussion on ways to predict earthquakes, the three main points made in the reading are effectively challenged by the lecturer.
