A scientist performs a controlled experiment. This means that
A) the experiment is repeated many times to ensure that the results are accurate.
B) the experiment proceeds at a slow pace to guarantee that the scientist can carefully
observe all reactions and process all experimental data.
C) the experiment consisted of an experimental group and a control group that were
compared.
D) two experiments are conducted, one differing from the other by two or more
variables.
E) the experiment consisted of a control group that was carefully chosen to be the
opposite of the treatment group which was chosen at random.
I know it is not D because it is only one single variable. A is not bc it says "many times"
