1.
The scientific method is a method to establish causal relations between aspects of nature. It includes several rules; for example, the rule that cause and effect should be observed in controllable repeated manner. A hypothesis is a part of a scientific method that allows predicting the outcomes in accordance with hypothesis that is being testified. Hence, the option 'b' is incorrect.
2.
Hypothesis testing is part of a hypothesis-driven research. Discovery-based science, on the other hand, does not use hypotheses, but rather other methods for selecting the objects of research. One method could screen large group of effectors in the action on a particular object. Thus, the option 'c' is incorrect.
3.
The result of an experiment is tested by exclusion of a single factor that the experiment claims to cause an effect on outcome. This is called a control experiment that serves to establish background for comparison with the outcome of an experiment. This procedure is part of the scientific method and not a description of an experiment conducted without a conceived hypothesis. Thus, the option 'd' is incorrect.
4.
Conducting research without a preconceived hypothesis is called discovery-based science, which is answer 'a' in the quiz. Therefore, the statement 'none of the above' is not correct. Thus, the option 'e' is incorrect.
5.
Conducting research without a preconceived hypothesis is called discovery-based science. This kind of research could produce facts that would serve as foundations for new chapters and even branches of science. This kind of research may also result in discovery of new products that would benefit people. For example, testing of several materials has led to discovery that tungsten wire serves longer in the lamp bulbs than carbon wire. Testing the effect of several small organic molecules in cell cultures could result in discovery of new drugs.
Hence, the correct option is (a) discovery-based science.
