Which of the following is a disadvantage of conducting a laboratory experiment?

A. Cause-and-effect relationships are easier to determine in laboratory experiments.

B. Laboratory experiments do not generally reflect real-life circumstances.

C. There is more objectivity in measuring the dependent variable in laboratory experiments.

D. Replicating the study is difficult for laboratory experiments.

The correct answer is B. Laboratory experiments do not generally reflect real-life circumstances.

Explanation:

An experiment refers to a procedure that tests and therefore proves or refutes a hypothesis. Experiments can be conducted in the natural environment or context where they occur or in a laboratory or controlled context. In this case, the scientist or researcher can measure more precisely the phenomenon studied and replicate the same experiment under similar or identical circumstances which is an advantage; however, as it is the scientist the one that controls and even creates the circumstances for the experiment this might show different results to the ones in natural context as laboratory circumstance might not reflect reality.

Answer: The correct answer is : B. Laboratory experiments do not generally reflect real-life circumstances.

Explanation: One of the advantages of laboratory experiments is that cause-effect relationships are easier to consider. In a laboratory the independent variables are manipulated by the experimenters.
