Answer:
On March 26, 1953, American medical researcher Dr. Jonas Salk announces on a national radio show that he has successfully tested a vaccine against poliomyelitis, the virus that causes the crippling disease of polio. In 1952—an epidemic year for polio—there were 58,000 new cases reported in the United States, and more than 3,000 died from the disease. For promising eventually to eradicate the disease, which is known as “infant paralysis” because it mainly affects children, Dr. Salk was celebrated as the great doctor-benefactor of his time.
Explanation:
This isn't a great story, to be quite honest. The story focuses less on the ways man used to start fires and more on the ways that nature started fires independently of humans.
That being said, it would seem as though the author is trying to express the fragility of fire early on, and it does seem as though he/she is saying that early on, humans just found a small amount of fire from a really dangerous origin to use as a kindling.
For sure, your answer should come from the second paragraph, which is the paragraph describing early kindling methods.
