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) The level of skill required for laboratory technicians to perform the new test is higher than that required to perform previous tests for Salmonella.
(B) The new test returns results very soon after food samples are submitted for testing.
(C) A proposed new treatment for Salmonella poisoning would take effect faster than the old treatment.
(D) Salmonella poisoning is becoming less frequent in the general population.
(E) Some remedies for Salmonella poisoning also cure intestinal disorders caused by other microorganism.

Correct answer: B
(A): Incorrect. (A) tends to weaken the argument by indicating that it may be more difficult to administer.
(B): Correct. One of the difficulties of salmonella diagnosis currently is speed; if the new test is both more accurate and faster, then it will likely be preferable to the old test.
(C): Incorrect. Out of scope: the argument only concerns tests, not treatment, for salmonella.
(D): Incorrect. Irrelevant: whether salmonella is more or less prevalent does not bear on the efficacy of testing for it by one test versus another.
(E): Incorrect. Out of scope; as in (C), the argument cocerns testing for Salmonella, not treatment.
