Answer 1

The true statement is:

There was a consensus among scientists that miasma caused diseases by the 19th century.

During the early 19th century, the miasma theory, which suggested that diseases were caused by "bad air" or miasmas arising from decaying matter, was widely accepted. The germ theory of disease, which established that microorganisms (germs) are the cause of many diseases, gained prominence later in the 19th century, notably through the work of scientists like Louis Pasteur and Robert Koch.
