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?\nthe observed results are different from the expected results.\nthe investigation had many sources of error.\nanother scientist proposed the same theory.\nthe expected results could be explained in different ways.
Answer
# Brief Explanations:
When observed results deviate from expected ones based on accepted theories, it indicates that there may be something wrong with the initial assumptions or the theory itself. This prompts scientists to ask new questions to understand the underlying reasons. Many sources of error just affect the reliability of the current investigation but may not necessarily lead to asking a completely different question. Another scientist proposing the same theory doesn't change the need to test the theory further. Multiple ways to explain expected results don't usually trigger a new - question as much as unexpected results do.
# Answer:
The observed results are different from the expected results.
