▶ Your Answer :
Both reading and the lecture is about
will-o’-the-wisp, which is appearance of glowing lights over marshes and other
wetlands. The author of the reading believes that some scientific hypothesis
can explain this phenomenon. However, the lecturer casts doubt of the claims
made in the article. She thinks that suggested hypothesis in the reading are
not convincing.
First of all, the author argues that the
light is formed from chemical reactions. Phosphine gas which rises from rotting
organics around wet lands and other gases chemically react to give off a glow.
However, this point is challenged by the lecture. She says that color of the
light created from phosphine gas and will-o’-the-wisp is different. The
chemical reaction emits cool-green light while the actual color of will-o’-the-wisp
is warm yellow color.
Secondly, the author mentions that the
flying insects could provide the source of the eerie light. He states that the
fact that light-radiating insects are frequently found in areas where will-o’-the-wisp
occurs can support the hypothesis. The lecture, on the other hand, posits that
flying insects do not stay in one area but they spread over large areas. Also,
they radiate lights in blinking pattern whereas will-o’-the-wisp just steadily
glows.
Finally, the author says that the light
could be a reflection of light on barn owls white plumage. He mentions that because
owls are nocturnal, the reflection is seen at night. The lecture refutes this argument. She says the
fact that barn owls are not entirely white and that there is no light source in
wetlands together suggest that barn owls are not the cause of the phenomenon.
