The reading is explaining the causes of the asthma and also how it affects the bronchial tubes. The lecture complements this information by discussing the concept of remodeling caused by asthma episodes.

The lecture explain that there is new evidence that explain how bronchial tubes returns to a normal state after an asthma attack. He explains that it was though that airways was narrowed by inflamation, but a recent study reveals that it is cause by remodeling. While the reading states that asthmatics are brought on by the environment, the lecture says that this condition is caused by remodeling. The proffesor talks about a recent study on young children that shows that ashtmatics already have remodeled.

Secondly, the lecture shows that this disease is caused by a genetic factor and the environment.

The lecture and the reading are both discussing about the practice for finding water underground called dowsing. While the reading claims that dowsing works, the lecture contradicts it by giving some reasons.

First of all, the professor explains that extraordinary claims needs extraordinary evidences to be accepted. We cannot accept dowsing as a succesful practice due to the fact that there is no evidence that support it. The reading says that it is a millennia-old art that have plenty of witnesses that support that it works.

Secondly, the lecture states that some studies made with strict conditions shows that dowsing is not succesful. She explains that it is hard to imagine how some people find water with dowsing even if the most recent technology cannot detect it.
