Question

a fortunate mistake
before doctors could prescribe antibiotics (medicines that kill bacteria), many people were badly affected each year from illnesses that are now easily treated. the first antibiotic was discovered by a scottish professor named alexander fleming in 1928. fleming was researching bacteria in a hospital in london, england, when he left to go on vacation for two weeks. while he was gone, he left samples of bacteria sitting in his laboratory. when he returned, he found that one of the samples had been polluted by white mold. when he was preparing to dispose of the moldy sample, fleming noticed something unusual. the bacteria near the mold had unexpectedly stopped growing. fleming began to experiment and soon discovered that liquid from the mold could also kill other harmful bacteria. fleming wrote about what he discovered, and other scientists wanted to know more. other researchers continued flemings work in the hope that they could use the discovery to treat disease. they developed penicillin, an antibiotic which was soon being used around the world. over time, many more antibiotics have been developed.

inference|evidence
mold damaged the bacteria samples in the laboratory.|they developed penicillin, an antibiotic which was soon being used around the world.
many people have benefited from flemings mistake.|when he returned, he found that one of the samples had been polluted by white mold.
the polluted sample was of little use for flemings work.|fleming wrote about what he discovered, and other scientists wanted to know more.
other scientists were curious but didnt think the discovery was important.|when he was preparing to dispose of the moldy sample, fleming noticed something unusual.
over time, many more antibiotics have been developed.

Explanation:

1. Inference: Many people have benefited from Fleming's mistake. This is because his accidental discovery led to the development of penicillin, an antibiotic used worldwide, which has clearly helped many people with bacterial - related illnesses.
2. Evidence 1: When he returned, he found that one of the samples had been polluted by white mold. This is the starting - point of the accidental discovery.
3. Evidence 2: They developed penicillin, an antibiotic which was soon being used around the world. This shows the practical and far - reaching benefit of the discovery.

Answer:

Inference: Many people have benefited from Fleming's mistake.
Evidence: When he returned, he found that one of the samples had been polluted by white mold.
Evidence: They developed penicillin, an antibiotic which was soon being used around the world.
