Scientist P: A new drug cures a cold by killing the virus directly. Scientist Q: The drug cures the cold by boosting the immune system's white blood cell count. In a lab trial, the drug is added to a test tube containing the cold virus but NO white blood cells.
If the virus count remains exactly the same after 48 hours, which scientist is undermined?
- Neither scientist, because 48 hours is not long enough for most drugs to penetrate the protective outer shell of a virus particle.
- Scientist Q, as the fact that the virus didn't die proves that white blood cells are not necessary for the drug to be effective in humans.
- Both scientists, because cold viruses are known to be completely immune to any pharmacological treatment in a laboratory setting.
- Scientist P, because the drug failed to kill the virus when the immune system components were removed from the environment.
