Ultraviolet radiation from the sun can damage not only eyelid skin but also the cornea and conjunctiva, which are the clear outer parts of the eye. UV exposure also contributes to the development of cataracts. Blue-blocking sunglass lenses, which are typically yellow or orange. may make distant objects easier to see, especially in low light. However, such lenses may also make the hues in traffic lights difficult to discriminate. Meanwhile. not all blue-blocking lenses offer adequate UV protection.
Which of the following can be properly inferred from the above statements?
(A) Ultraviolet radiation is the most serious threat to eye health.
(B) Eyelid skin is more sensitive to direct sunlight than are other parts of the human face.
(C) Blue-blocking lenses should not be used when driving.
(D) Some sunglasses may leave their wearers vulnerable to eye problems.
(E) No amount of sum exposure can be considered safe.

Hi Doer01
In Conclusion/Inference question type, we are looking for a guaranteed 100% correct stated/inferred information in the passage.
In Assumption question type, we are looking for UNTOLD necessary information to link premise with a conclusion (filling a gap).
The question we are discussing is Inference type.
(C) is an assumption built on the info that "lenses MAY make the hues in traffic lights difficult to discriminate"
here there are 2 problems:
1. although the passage used "MAY make", option "C" used "SHOULDN'T" as if it is a 100% certain threat --> Language strength is very important
2. Our task is not to assume, but to infer an information we can be 100% sure of.
(D) is a correct inference based on solid info from the passage.
The passage discusses "Blue-blocking sunglass" (which is some kind of eyeglasses);
and mentions that "NOT ALL blue-blocking lenses offer adequate UV protection" (which means that the eyeglass MAY not be able to protect its wearer from UV),
and warned that "Ultraviolet radiation from the sun can damage not only eyelid skin but also the cornea and conjunctiva" (which are examples of eye problems).
why D is correct?:
1. it is not as assumption, but a rephrasing for information already stated.
2. suitable language strength (Not all ---> May)

Hi,
C & D both seem to be strong contender. I chose C sighting the difficulty in differentiating traffic lights.
How could one reject C on solid grounds and choose D instead when D is a bit open ended inference?
(C) Blue-blocking lenses should not be used when driving.
(D) Some sunglasses may leave their wearers vulnerable to eye problems.
