xamine the scenario.

A scientist wishes to discover whether dinosaurs were warm-blooded or cold–blooded. However, he cannot directly perform any measurements or experiments because dinosaurs are extinct.
What aspects of scientific thinking can help him study this question and still follow the scientific method?
(Select all that apply)
practice skepticism and avoid accepting any opinions as an absolute fact
practice empiricism and avoid practicing any other methods
practice deductive reasoning by studying living warm- and cold-blooded creatures
practice rationalism in order to formulate explanations

To study whether dinosaurs were warm-blooded or cold-blooded using the scientific method, the scientist can employ several aspects of scientific thinking:

1. Practice skepticism and avoid accepting any opinions as an absolute fact: The scientist should question existing theories or assumptions about dinosaur physiology, taking a critical approach to ensure that they do not blindly accept any claims without evidence.

2. Practice empiricism and avoid practicing any other methods: Empiricism involves relying on evidence derived from observations and experiments. Since direct experiments on dinosaurs are not possible, the scientist can analyze existing fossil records, study dinosaur anatomy, and compare it with that of living warm- and cold-blooded creatures to draw conclusions.

3. Practice deductive reasoning by studying living warm- and cold-blooded creatures: By observing and studying the physiology, metabolism, and behavior of living warm-blooded and cold-blooded creatures, the scientist can make deductions and apply that knowledge to infer about dinosaur physiology.

4. Practice rationalism to formulate explanations: Rationalism involves using logical reasoning and prior knowledge to formulate explanations. The scientist can use the information gathered from empirical observations, prior research, and comparisons with living creatures to develop hypotheses and theories about dinosaur thermoregulation.

Therefore, all of the options mentioned—practicing skepticism, empiricism, deductive reasoning, and rationalism—can help the scientist study the question about dinosaur physiology while following the scientific method.
