Question

[3]. Read the following passage carefully and answer the question.

Passage: In 1928 Alexander Fleming returned to his London laboratory after a holiday and noticed something strange on a discarded culture plate. A mould had grown on the plate, and around it the bacteria had stopped growing. Fleming did not throw the plate away. He studied the mould, identified it as Penicillium, and showed that the substance it produced could kill many harmful bacteria. The discovery did not at once become a medicine. It took more than a decade of work by Florey and Chain to purify penicillin and test it safely in patients. Yet the first step was simple observation: a careful scientist noticed what others might have ignored and asked why it had happened. In the context of the passage, the word 'culture' most nearly means:

1.
a book or document written by hand before printing
2.
moving back, becoming smaller over time
3.
a growth of bacteria in a laboratory dish
4.
a group of travelling performers
