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?
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? (A) If a field of study can conclusively answer the questions it raises, then it is a genuine science. (B) Since parapsychology uses scientific methods, it will produce credible results. (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. (E) Since parapsychology raises clearly statable questions, they can be tested in controlled experiments.
en ,我刚才想了想,明白了,因为题眼在于Any enterprise that does not use controlled experiments and statistical tests is not genuine science里面controlled experiments and statistical tests是列举scientific methods 的两个例子,实际上可以有很多很多的方式,所以单单否定这两个OPTIONS, 是不足以证明的。一种包含与被包含的关系。
Any enterprise that does not use controlled experiments and statistical tests is not genuine science.
A=use controlled experiments and statistical tests B=it's a genuine science
if not A, then not B 等价于 if B, then A 翻译过来是 if it is a genuine science, it uses controlled experiments and statistical tests. 而原文的Assumption是: Premise: it uses scientific methods, such as .... Conclusion: it is a genuine science Assumption: if use scientific methods => genuine science 两者意思不一样,再说了experiments, tests 是 methods的实例,在assumption题中,把这种实例放在选项中构成假设很可能是错的~~~
