Vitamin D and the Sun

GMAT-YHEV1G

A recent study has indicated that people need more Vitamin D from forty minutes of direct sunlight; consequently, the researchers have suggested that everyone use less sunscreen.

Which of the following is the flaw in the logic?

A

People could get some of their Vitamin D from other sources.

B

Most individuals with jobs that require a lot of indoor work do not wear sunscreen during the work week.

C

Sunscreen with a UV rating above 50 ensures less of a chance of sunburn than those below a 50 rating.

D

More direct sunlight may lead to more serious problems than a vitamin deficiency.

E

Individuals who go to the beach regularly have skin types that are not affected either way by the use of sunscreen.
