Thinking Like a Scientist
When it comes to thinking like a scientist, a key aspect is the ability to test ideas. In the scientific method, this involves making observations, formulating hypotheses, and designing experiments. One trait of scientific thought, which distinguishes it from everyday thought, is the ability to test hypotheses. This process is critical as it allows scientists to validate or refute the tentative explanations that they put forward for a given observation. Unlike simply making claims or forming opinions, testing hypotheses involves a systematic approach to investigation that is evidence-based and can lead to conclusions about the natural world. Scientific inquiry is an iterative process, with each hypothesis test leading to further questions and experiments.
The correct answer to the question is C) test hypothesis.
