Answer

Brief Explanations:

New scientific knowledge about the transmission of malaria and yellow - fever (mosquito - borne diseases) allowed for better prevention measures. This led to fewer workers getting sick, which was crucial for the construction of the Panama Canal. Radios, nutrition, and airplanes are not directly related to new scientific knowledge in the context of disease prevention for the canal - building workforce.

Answer:
