Question

the author states that animals and humans share 98 percent dna. how does the author help readers understand the importance of this?
a by highlighting the different kinds of apes
b by using common examples to explain
c by describing a film about a fictional ape
d by explaining how genetic tests work

Explanation:

Using common - examples helps make complex scientific information (like the significance of shared DNA) more relatable and understandable to general readers. Highlighting different apes doesn't directly explain the importance of shared DNA. Describing a fictional ape film is more for entertainment - value than explaining scientific importance. Explaining how genetic tests work is off - topic from the importance of the shared DNA fact itself.

Answer:

B. by using common examples to explain
