Question

Can someone please tell me if the correct answer is #2 (results in chickens cannot be fairly compared to results in humans?

Christiaan Eijkman shared the Nobel Prize in 1929 for the discovery of vitamins. Eijkman went to Java to isolate the pathogen that was the cause of beriberi, an illness that appeared to be contagious as it was common in prisons and ships crews. Eijkman noticed that chickens fed a diet of white rice also suffered from a similar disorder. When the chickens were fed a diet of red rice, the chickens quickly recovered. Eijkman returned to the Netherlands and persuaded a prison to feed the prisoners red rice, and the incident of beriberi decreased. In what way was Eijkman's work unscientific?

The experiment with human subjects lacked a control.

Results in chickens cannot be fairly compared to results in humans.

The red rice was not given to all the prisoners with beriberi.

The results were not published before being acted upon.
