Salmonella is a food-borne microorganism that can cause intestinal illness. The illness is sometimes fatal, especially if not identified quickly and treated. Conventional Salmonella tests on food samples are slow and can miss unusual strains of the microorganism. A new test identifies the presence or absence of Salmonella by the one piece of genetic material common to all strains. Clearly, public health officials would be well advised to replace the previous Salmonella tests with the new test. Which one of the following, if true, most strengthens the argument?
A: Some remedies for Salmonella poisoning also cure intestinal disorders caused by other microorganisms.
B: Salmonella poisoning is becoming less frequent in the general population.
C: The new test returns results very soon after food samples are submitted for testing.
D: The level of skill required for laboratory technicians to perform the new test is higher than that required to perform previous tests for Salmonella.
Choose A, B, C or D as your solution.
