After spreading throughout much of europe in 1348, the bubonic plague killed approximately
a) one-third of europe's population.

c) one-sixteenth of europe's population.
d) one-twentieth of europe's population.

With the poor hygienic conditions of the medieval cities, the plague managed to find an environment favorable to its propagation among people. Garbage and excrement through the streets, in addition to small dwellings and with many people, facilitated the reproduction of the rats and the contact of the people with the fleas.

The impact of the loss of such a large number of people marked the scientific, cultural, religious and artistic production of the period. In addition to the painting by Pieter Brueghel, The Triumph of Death (above), one can cite the passage from the book Decameron, by Giovanni Boccaccio.

The disease arrived in Europe, possibly from Central Asia, around 1347, when the first outbreak occurred. On commercial routes, besides merchandise, rats were also transported by merchants. It was almost impossible to avoid the presence of these animals. With the bacteria reaching the cities, the black plague soon spread. It was also spread from person to person, because it developed in the pneumonic form, being transmitted through coughing or sneezing. Causing an epidemic that killed 1/3 of Europe's population.
