A career in dermatology is still a safe bet for medical school graduates. In the U.S., the number of cases of skin cancer linked to ultraviolet (UV) radiation in sunlight has remained relatively constant every year even though far fewer adults are intentionally exposing themselves to UV sunlight now than were doing so at the height of the suntan craze 20 years ago.

Each of the following, if true, could explain the relative stability in the incidence of skin cancer each year despite the decrease in intentional exposure to UV sunlight EXCEPT:


(A) Because of decreasing levels of ozone in the upper atmosphere, more people are now exposed accidentally to excessive UV sunlight.

(B) People who continue to intentionally expose themselves to UV sunlight are absorbing larger doses of the harmful radiation than the average sun-tanner did in the past.

(C) Levels of UV radiation from sources other than sunlight are increasing every year.

(D) While fewer women are intentionally exposing themselves to UV sunlight, the number of men doing so has increased significantly.

(E) In most victims, skin cancer is linked to exposures to UV sunlight that occurred up to 30 years before the onset of the disease.

Given: 1.Number of cases of skin cancer linked to UV radiation in sunlight has remained relatively constant every year
2.Far fewer adults are intentionally exposing themselves to UV sunlight now than were doing so at the height of the suntan craze 20 years ago.

Type of question: EXCEPT

Reasoning:Correct me if i am wrong,
(A) Because of decreasing levels of ozone in the upper atmosphere, more people are now exposed accidentally to excessive UV sunlight- explains the cause of cancer.Even though few adults are intentionally exposing,but due to reason specified they are exposed accidentaly.So it explains.Eliminate.

(B) People who continue to intentionally expose themselves to UV sunlight are absorbing larger doses of the harmful radiation than the average sun-tanner did in the past-Correct

(C) Levels of UV radiation from sources other than sunlight are increasing every year.-Other source of radiation ,here alternative cause explained ,so eliminate

(D) While fewer women are intentionally exposing themselves to UV sunlight, the number of men doing so has increased significantly- Irreleveant as not about male/female but about adults

(E) In most victims, skin cancer is linked to exposures to UV sunlight that occurred up to 30 years before the onset of the disease.-Since cancer caused due to time older than 30 years,it explains the cause.

Imo D
This is an except question and we have to be careful that we keep that in mind.

A this actually helps to explain the relative stability of skin cancer among folks.

B This helps that people mistakenly are receiving more doses of UV radiating leading to skin cancer. Thus this choice also helps to explain the stability.

C Again if this the case then more people will be exposed to more UV radiation and they might not know the source.

D Correct. While this choice breaks up the population in gender, still this does not explain stability in the skin cancer. More men are exposing themselves than women this can lead to various cases and we do not know the number of female or female to ascertain the overall impact of such trend. This is our answer.

E This choice also explains the stability of the cancer.

A career in dermatology is still a safe bet for medical school graduates. In the U.S., the number of cases of skin cancer linked to ultraviolet (UV) radiation in sunlight has remained relatively constant every year even though far fewer adults are intentionally exposing themselves to UV sunlight now than were doing so at the height of the suntan craze 20 years ago.

Each of the following, if true, could explain the relative stability in the incidence of skin cancer each year despite the decrease in intentional exposure to UV sunlight EXCEPT:


(A) Because of decreasing levels of ozone in the upper atmosphere, more people are now exposed accidentally to excessive UV sunlight.
So more people are getting exposed accidentally...does explain

(B) People who continue to intentionally expose themselves to UV sunlight are absorbing larger doses of the harmful radiation than the average sun-tanner did in the past.
Now the exposure has increased, so incidence of cancer has remained relatively constant....... A close second to choice D

(C) Levels of UV radiation from sources other than sunlight are increasing every year.
clearly explains

(D) While fewer women are intentionally exposing themselves to UV sunlight, the number of men doing so has increased significantly.
women may have stopped and more men may have increased but overall we know the exposure by adults has decreased. Doesn't matter what constitutes the adults who are exposing themselves but the number has decreased... Doesn't explain

(E) In most victims, skin cancer is linked to exposures to UV sunlight that occurred up to 30 years before the onset of the disease.
again explains. The present cases are related to time when exposure was more

D

D is my choice and it clearly goes reverse telling higher number of adults are exposing themselves to suntan as compared to before.
