scientists base many of their investigations on questions that test accepted theories. which outcome of an investigation would cause a scientist to ask a different question? the observed results are different from the expected results. the investigation had many sources of error. another scientist proposed the same theory. the expected results could be explained in different ways.
Answer
# Brief Explanations:
When observed results deviate from expected ones based on an accepted theory, it indicates that the theory may need re - evaluation or that there are unaccounted - for factors. This prompts scientists to ask new questions to understand the discrepancy. Sources of error may just lead to repeating the investigation, another scientist proposing the same theory is not a reason for a new question, and different explanations for expected results do not necessarily prompt a new question as the results match expectations.
# Answer:
The observed results are different from the expected results.
