In Ms. Bull's class, we are trying to figure out why the Skin Cancer rate in Australia is so high. We disproved the Claim (the answer), which states that the cancer rate in Australia is high because Australia gets a lot of sun.

Why did we disprove this Claim? Select ALL answers that apply.

(Hint hint: There's more than 1 answer)

• Australia gets the same amount of sunlight as Brazil per year, but the skin cancer rate in Australia is higher than Brazil.

• Australia gets less sunlight than Northern Africa (Egypt) per year, but the skin cancer rate in Australia is higher than Egypt.

• Australia gets the same amount of sunlight as Brazil per year, but the skin cancer rate in Australia is lower than Brazil.

• Australia gets more sunlight than Northern Africa (Egypt) per year, but the skin cancer rate in Australia is lower than Egypt.
