In which year did London experience the Great Plague?

• A. 1665
• B. 1660
• C. 1666
• D. 1655

Answer: (A)

The question is testing your knowledge of when the Great Plague struck London. The epidemic is most famously dated to the year when it reached its height and caused the largest impact on the city, which is 1665. That year saw the peak in deaths and is how historians typically refer to the Great Plague in London. The plague did continue into early 1666, but 1665 is the defining, widely remembered year.

Context helps: this outbreak is remembered as the last major English plague epidemic and had a profound effect on London's population and surviving public health measures. The Great Fire in 1666 is often noted as helping to end the outbreak by burning infected areas, which is why the following year is less associated with the plague. The other dates mentioned are years without the same scale of London-wide outbreak.
