Final answer:
Scientists B) gather evidence, ask and answer questions, and follow the scientific method to understand the world around them. Hence, B) is correct.
Step-by-step explanation:
Scientists are engaged in explaining and understanding how the world around them works, and they are able to do so by coming up with theories that generate hypotheses that are testable and falsifiable. Theories that stand up to their tests are retained and refined, while those that do not are discarded or modified. In this way, research enables scientists to separate fact from simple opinion. Having good information generated from research aids in making wise decisions both in public policy and in our personal lives.
Thinking like a scientist is based on asking and answering questions. Though you may not know it, you do this all day long. Scientists ask questions, and then make detailed observations to try to ask more specific questions and develop a hypothesis. They may design and perform an experiment to try to answer their question and test their hypothesis. From the results of their experiment, scientists draw conclusions. A conclusion describes what the evidence tells the scientist.
