Although parapsychology is often considered a pseudoscience, it is in fact a genuine scientific enterprise, for it
uses scientific methods such as controlled experiments and statistical tests of clearly stated hypotheses to
examine the questions it raises.

The conclusion above is properly drawn if which of the following is assumed?


c.Any enterprise that does not use controlled experiments and statistical tests is not genuine science.
d.Any field of study that employs scientific methods is a genuine scientific enterprise.

是不是不能反过来说?

Here a gap is needed to fill in the jump in the stimulus. The gap is just what D says.

Btw, the prompt is asking for a Sufficient Assumption. Negation method can be used for Necessary Assumption questions rather than for Sufficient Assumption ones.

C取非,是Any enterprise that does not use controlled experiments and statistical tests is genuine science.不能削弱结论,因为即使不用试验和数据的都是genuine science,也不能说明用的就不是。
结论concern的是what is genuine science,而不是what is not genuine science.
