Sarah, a citizen of the United States, has emigrated to Australia. She has been advised by her skin doctor to take every precaut
ion to protect her skin at all times. What could be the reason behind this concern? A.
No reason. Her skin doctor is being overly cautious.
B.
Being new to the country, it is safer for Sarah to take precautions until she gets acclimated.
C.
Australia faces a threat of overexposure to UV radiation.
D.
Australia's hot weather could cause Sarah’s skin to burn.
E.
The doctor may be cautious because Sarah may be genetically predisposed to skin afflictions.
Australia has less ozone over it than the country Sarah is coming from. This ozone layer helps to prevent some of the UV radiation from reaching the surface. Australia is about exposed to about 7% more radiation. Also, there are often high-pressure systems over much of Australia which means that the incoming solar radiation is not reflected off clouds, causing it to land on the surface.
