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? ['Since parapsychology raises clearly statable questions, they can be tested in controlled experiments.', 'Any field of study that employs scientific methods is a genuine scientific enterprise.', 'Any enterprise that does not use controlled experiments and statistical tests is not genuine science.', 'If a field of study can conclusively answer the questions it raises, then it is a genuine science.']
