Final answer:
A project has a definite beginning and end-point, so the statement is false. While experiments allow scientists to make cause-and-effect claims, they can have limitations, which is true. A good research question should be open-ended and debatable to promote comprehensive investigation and discussion.
Step-by-step explanation:
The statement that a project is typically open-ended, with a definite beginning but not a definite end-point, is false. By definition, a project is a temporary endeavor undertaken to create a unique product, service, or result. It has a clear beginning and also a definite end-point, at which the goals of the project are expected to be achieved and the project activities cease.
Regarding the conduct of experiments, the statement that experiments allow scientists to make cause-and-effect claims is true. However, it is also true that experiments can have limitations and are not without problems, which can include issues such as ethical considerations, practical constraints, and potential biases.
When formulating research questions, it is important to ensure that the question is open-ended and debatable to stimulate in-depth research and discussion. This means that the question should not have a simple yes-or-no answer and should not have an obvious solution, but instead should allow for multiple plausible answers and spark reasonable debate among scholars and researchers.
