▶ Your Answer : The reading and lecturer are both concerned with the cow's ability to detect the earth's magnetic field. The reading of author believes that cow populations can point towards north or south. However, the lecturer casts doubt on the claims made in the article.The lecturer thinks that cows can't detect magnetic field. First of all, the author points out that cows are able to detect the magnetic field of the earth's poles like many animals. It is mentioned that cows are similar to wild deer that can make tracks aligning to north or south. This point is challenged by the lecturer. The lecturer suggests that cows don't resemble with other animals which detect magnetic field. She argues that while other animals such as fish and birds can find their way by detecting magnetic field, cows only know north or south when they eat and sleep.
Secondly, the author contends that a major study of satellite pictures were more likely to demonstrate that cows from all over the world pointed toward north or south poles at the same time of day. The author notes that satellite pictures denotes that all cows were inclined to face in same directions. The lecturer refutes by mentioning that all of animals in satellite picture aren't cows. Furthermore, she says that its picture shows not groups of cows but a single cow and their animals are on the hills.
Finally, the author states that cows placed near electrical power lines will point in radom directions. The author establishes that if cows are far away from power lines, they would align to north or south. THe lecturer, on the other hand, contradicts this argument. She insists that just only one teams made this conclusion. Other teams thinks that if cows can detect magnetic field, close proximity to power lines would had distorted their perception and point different directions. |
