\day we discovered cause of white death\
by dr. howard markel
like many young physicians at the era, koch was struck by an intense fascination with all things microbiologic, a fixation borne mostly of otto’s derision as “microbe-obsessive.” (unlike his senior colleagues who scoffed at the consideration of the new germ theory, dr. koch) sided with those who would embrace the scientific possibilities of their day by asserting and ultimately proving that specific microbes were the cause of specific infectious diseases.
which states a cause-and-effect relationship found in the excerpt?
(1 point)
○ epidemics are caused by specific microbes.
○ diseases caused foul or unpleasant emanations.
○ dr. koch’s colleagues’ unwittingly caused the crisis.
○ doctors challenged dr. koch, so he sided with revolutionaries.

Explanation:

The passage states that Dr. Koch proved specific microbes cause specific infectious diseases. The other options are incorrect: his colleagues blamed foul air/emanations, there is no mention of colleagues causing disease, and the passage does not say doctors challenging him led to his alliance with revolutionaries.

Answer:

A. Epidemics are caused by specific microbes.
