Importance of ozone layer

Expert replies

Posting three critical reasoning questions in which I made mistake. Kindly feel free to discuss.

The importance of the ozone layer to terrestrial animals is that it entirely filters out some wavelengths of light but lets others through. Holes in the ozone layer and the dangers associated with these holes are well documented. However, one danger that has not been given sufficient attention is that these holes could lead to severe eye damage for animals of many species.

Which one of the following is most strongly supported by the statements above, if they are true?

A. All wavelengths of sunlight that can cause eye damage are filtered out by the ozone layer where it is intact.
B. Few species of animals live on a part of the earth's surface that is not threatened by holes in the ozone layer.
C. Some species of animals have eyes that will not suffer any damage when exposed to unfiltered sunlight.
D. A single wavelength of sunlight can cause severe damage to the eyes of most species of animals.
E. Some wavelengths of sunlight that cause eye damage are more likely to reach the earth's surface where there are holes in the ozone layer than where there are not.

IMO A, It says 'all wavelengths where as E talks about just few wavelengths that can cause damage that are filtered by ozone layer.

Mentioned in argument: ozone layer entirely filters out some wavelengths but lets others through.
How can you say that all wavelengths that can cause eye damage are filtered out??

Looks like an inference/must be TRUE Q
IMO E
[spoiler]A,B,C&D[/spoiler] cannot be inferred from argument.

It is E

A. All wavelengths of sunlight that can cause eye damage are filtered out by the ozone layer where it is intact. strong wording.
B. Few species of animals live on a part of the earth's surface that is not threatened by holes in the ozone layer. We do not know few or many
C. Some species of animals have eyes that will not suffer any damage when exposed to unfiltered sunlight.strong wording.
D. A single wavelength of sunlight can cause severe damage to the eyes of most species of animals. .strong wording.
E. Some wavelengths of sunlight that cause eye damage are more likely to reach the earth's surface where there are holes in the ozone layer than where there are not.
The more you suffer before the test, the less you will do so in the test! :)
