question 1

Multiple Choice

A researcher reports he has conducted many experiments where a galvanometer (lie detector) was hooked up to detect a plant's responses. He reports that when a spider was released near the plant, the spider's decision to escape was picked up by the plant, "causing a reaction in the leaf." When other researchers repeated the experiment, they could not get any galvanometer responses. The researcher then concluded that plants could be put into a faint by humans.

• B) The only problem with this general research plan is that it lacks a control.
• C) Results must be somewhat repeatable and these results that only work for this researcher do not qualify as science.
• D) The design is scientific; it just lacks a hypothesis.
• E) If the researcher has actual numerical counts, this must be accepted as valid science.
