Question

match the effect to the cause.
cause: dr. james lind wanted to find the best treatment for scurvy.
effect: consequently, he received the nobel prize.
effect: therefore, he helped sick sailors find other work.
effect: so, he conducted an experiment with six treatments.

Explanation:

Dr. James Lind's goal was to find the best treatment for scurvy. Logically, the next step would be to conduct an experiment (as experiments are a common way to test treatments). Receiving the Nobel Prize is not a direct consequence of just wanting to find a treatment (more significant and widespread contributions are usually needed for that). Helping sailors find other work is also not a direct effect of wanting to treat scurvy. Conducting an experiment with six treatments is a direct action taken to achieve the goal of finding the best treatment.

Answer:

So, he conducted an experiment with six treatments.
