The Method of Agreement Is Particularly Useful When

The method of agreement is particularly useful when:

A) we want to narrow down the range of phenomena in question for possible further scientific research.
B) we are interested in pinpointing the exact cause of a phenomenon such as an epidemic.
C) we cannot separate the cause we are interested in from the effects it is entan- gled with though we do know what some of the other causes are.
D) we have a phenomenon to study that cannot be disconnected from a network of other significant factors, and any experiment involving the elimination of factors one by one is impossible.
