which best describes the purpose of a controlled experiment?\no to make sure the results of the experiment support the hypothesis\no to prevent a dangerous condition resulting from a reaction\no to examine whether one variable causes a change in another\no to prevent an undesired change in a variable

Answer

Brief Explanations:

A controlled experiment manipulates one variable (independent variable) to see its effect on another (dependent variable). It's not about ensuring results support a hypothesis (results should be objective), preventing dangerous conditions (not its main purpose), or preventing undesired changes in a variable.

Answer:

to examine whether one variable causes a change in another
