To speed up the publication process
To increase the number of citations for a paper
#20
Which of the following is a limitation of the scientific method?
It relies too much on empirical evidence
It cannot address ethical concerns
It may be influenced by biases and assumptions
It always leads to definitive conclusions
#21
What is the purpose of replication in scientific research?
To duplicate the original experiment exactly
To ensure the results are consistent and reliable

#22
What is peer review in the context of scientific research?
The process of evaluating the credentials of scientists
The process of scientists reviewing each other's research
The process of publishing research without review
The process of editing scientific papers
#23
What is the difference between a theory and a hypothesis in science?
A theory is supported by extensive evidence, while a hypothesis is a tentative explanation.
A hypothesis is supported by extensive evidence, while a theory is a tentative explanation.
A theory is proven to be true, while a hypothesis is still being tested.
A hypothesis is broader in scope than a theory.
