Do you think that this question is not well constructed?

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.

My opinion:
[Reveal] Spoiler:
I only would choose E by process of elimination. But I think that the question is not well constructed because there is no information to infer that the wavelengths are more likely to reach the earth’s surface where there are holes in the ozone layer. What do you think?
[Reveal] Spoiler: OA

(E)

(A) All wavelengths of sunlight that can cause eye damage are filtered out by the ozone layer where it is intact
- it entirely filters out some wavelengths of light but lets others through
(B) Few species of animals live on a part of the earth’s surface that is not threatened by holes in the ozone layer. - No mention of any parts of earth's surface
(C) Some species of animals have eyes that will not suffer any damage when exposed to unfiltered sunlight.
- these holes could lead to severe eye damage for animals of many species. Holes can lead to small damages.
(D) A single wavelength of sunlight can cause severe damage to the eyes of most species of animals.
- No mention of specific wavelenths
(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. --> Correct

Here,s my explaination::

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?

MUST BE TRUE question type by reading the stem.

(A) All wavelengths of sunlight that can cause eye damage are filtered out by the ozone layer where it is intact.
Eliminate: Extreme language.
(B) Few species of animals live on a part of the earth’s surface that is not threatened by holes in the ozone layer.
Eliminate: Goes out of scope.
(C) Some species of animals have eyes that will not suffer any damage when exposed to unfiltered sunlight.
Eliminate: No evidence is presented in the stimulus to prove this point.
(D) A single wavelength of sunlight can cause severe damage to the eyes of most species of animals.
Eliminate: Most is never equal to Many( as Powerscore says) . Most = 50 or above...but Many can include ALL.
(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.
Perfect: This one is basically a paraphrase of a line in the stimulus.

Hope it helps.

Thanks,

I think this is an OG question. Not sure of the number.But E makes the most sense. E is a paraphrase of the prompt in a very convoluted way!

Of all the answer choices, E seems to be mild and less extreme, while still supporting the argument

KUDOS
(A) All wavelengths of sunlight that can cause eye damage are filtered out by the ozone layer where it is intact. - Reject, nothing is said about filtering when ozone is intact, also all wave length is kinda huge jump, coz their might be come harmful light that effect the eye passing through
(B) Few species of animals live on a part of the earth’s surface that is not threatened by holes in the ozone layer. - Plain reject.
(C) Some species of animals have eyes that will not suffer any damage when exposed to unfiltered sunlight.- This was a nice contender for me, but i rejected it coz i dont know anything about other animal. All i have been told is some get eye problem.
(D) A single wavelength of sunlight can cause severe damage to the eyes of most species of animals. - Single, nah, reject.
(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. - This is totally fine !!, everything is given in the passage.

Even E cannot be the perfect answer because this option does not mention about whether species (or say many species) are living in areas where holes are observed. What if those are secluded or far on the earth and nobody lives there ??
