The main idea is about Dolphins. The 2 key details are how they take care of there babies and about their teeth.
I would go with B, or Ways to build immunity to diseases. Why? Well, just by using the word biology, we can use process of elimination. The prefix “bio” means life, so C and D already would be out. The suffix “ology” means the study of, so the word biology means the study of life. Because biology often has to do with diseases and finding cures to sustain human life spans, the only logical answer would be B. A would make no sense in terms of biology.

(x% * 4) + 4 = 4.32
Solve for 'x':
4x + 4 = 4.32
Subtract 4 to both sides:
4x = 0.32
Divide 4 to both sides:
x = 0.08
Multiply by 100:
0.08 * 100 = 8%
An easier way to do this is to find the percent increase.
First, subtract the two numbers.
4.32 - 4.00 = 0.32
Divide this to the original amount:
0.32 / 4.00 = 0.08
Multiply by 100:
0.08 * 100 = 8%
We basically did all the steps from our equation above.
