Albinism

by j_shreyans » Mon Sep 08, 2014 3:06 am
Guys ,

Pls help me out with the below problem with the explanation.



Albinism is a rare genetic condition that inhibits the production of melanin, or pigmentation, in the skin and hair. People born with albinism are unusually susceptible to sunburn, melanoma, and a range of other health issues that are generally connected to excessive exposure to the sun.

The statements above, if true, provide the most support for which of the following conclusions?

A)People born with albinism develop other biological protections against melanoma and other sun-related health issues.
B)Humans with a high production of melanin can easily ignore health issues related to exposure to the sun.
C)When a non-albino person gets sunburn, the amount of melanin produced by that person decreases.
D)In humans, melanin plays a role in protecting the skin from developing sunburn and other sun-related ailments.
E)It is not possible for a person born with albinism to adopt other artificial protective measures against excessive exposure to the sun.

D. If the lack of melanin in people means they are usually more susceptible to sunburn then it must play a role in protecting skin.

The statements above, if true, provide the most support for which of the following conclusions?

A)People born with albinism develop other biological protections against melanoma and other sun-related health issues. - Fails fact test. Incorrect.
B)Humans with a high production of melanin can easily ignore health issues related to exposure to the sun.- Fails fact test. Incorrect. The passage only talks about albinism.
C)When a non-albino person gets sunburn, the amount of melanin produced by that person decreases. - No mechanism explained and hence can't be deduced
D)In humans, melanin plays a role in protecting the skin from developing sunburn and other sun-related ailments. - Correct
E)It is not possible for a person born with albinism to adopt other artificial protective measures against excessive exposure to the sun. - The passage only says that they are unusually susceptible. Doesn't mean they can't be prevented.
