Though this has been discussed many times, but want to discuss option A in particular.
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.
OA E
Given in question-
-Ozone entirely filters out some wavelengths of light but lets others through.
-One danger that has not been given sufficient attention is that these holes could lead to severe eye damage for animals of many species.
Now holes in ozone may cause eye damage.
Where there are no holes there is no damage.
Ozone entirely filters out some wavelengths of light but lets others through.
This means all wavelengths of sunlight that can cause eye damage are filtered out by the ozone layer otherwise they will cause eye damage - this is exactly what option A says then why is it wrong?
Can any expert reply on this?
