Question

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?

Answer 1

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.

Answer 2

Any ideas?

Answer 3

I'm looking at A and D

Answer 4

b
i think

Answer 5

I think you're on the right track. Can you tell me your thought process?

Answer 6

well i know its not B

Answer 7

I'm thinking A

Answer 8

I agree that A would make sense. Without a control, there's no way of knowing if it was actually the red rice that made the prisoners better or if they just got better on their own. Controls are very important in scientific experiments!

Answer 9

very true! thanks!
