Answer: C. By 1980, just ten years later, the race had grown from 110 runners to over 20,000 people and had nearly outgrown the four-lane street.
Explanation:
The statement that least reveals the author's favorable bias is option B "By 1980, just ten years later, the race had grown from 110 runners to over 20,000 people and had nearly outgrown the four-lane street".
When compared to other options, we can see that option B is a statement that's based on evidence and facts. Other statements reveal the bias of the author as the statements show that the author is bias and giving opinions why he thinks the race is the best rather than backing the statements with facts.
