We wish to test if a certain vaccine developed for a disease is effective or not. What is the best way to do this? a)Vaccinate 100 animals and expose all 100 to the disease. Vaccinate 100 animals and expose 50 of them to the disease.

b)Vaccinate 50animals, do not vaccinate 50 other animals, and expose all 100 to the disease.

c)Vaccinate 50 animals, do not vaccinate 50 other animals, and expose the disease

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
