In order to come to the conclusion that their hypothesis is supported, what crucial step must a scientist perform? a)Gather information and do background research. b)Make observations and record the data. c)Communicate their results and allow peers to review their findings. d) Analyze their test results to look for patterns.

Explanation:

✦ In science, we usually refer to the scientific method:

  ✧ Question - What do you want to learn more about? What are you trying to figure out?

  ✧ Research - Gather your information that relates to the topic.

  ✧ Hypothesis - Form an "educated" guess of what will happen, what the answer will be.

  ✧ Experiment - Using steps, test your hypothesis.

  ✧ Analysis - Review all the information you collected from the experiment. As well as a written account of what happened.

  ✧ Conclusion - Was your hypothesis correct or not? Explain.

✦ Now for your question, if we look at the above scientific method what can we inquire that you need to PROVE that you hypothesis is correct:

  ✧ Gather information and do background research - This is a step but it's not crucial to PROVING the hypothesis.

  ✧ Make observations and record the data - This is a step but it's not crucial to PROVING the hypothesis.

  ✧ Communicate their results and allow peers to review their findings - This is a step but it's not crucial to PROVING the hypothesis.

  ✧ Analyze their test results to look for patterns - Yes! This is probably the most crucial step besides the actual test itself. When you analyze your data you can figure out if what happened in the test was what you said would happen in your hypothesis.

So It'd be D, Analyze their test results to look for patterns.
