I think it is called condensated matter
I do believe the answer is:D.

B
greenhouse effect describes Earth's atmosphere trap heat
Independent variable: calculators, computers
Dependent variable: speed
3 constants: seat, atmospheric condition, and time.
Control: none
<h3>What are variables</h3>
Variables are of different types in experiments. They can be:
- Independent: a variable that is supplied by the researcher and which can be tweaked among different experimental groups to produce different outcomes.
- Dependent: variables whose value is dependent on the kind of independent variable supplied by the researcher. It is the actual variable that is measured during the course of experiments.
- Constant: all other variables that are kept the same among experimental groups.
Thus, in this case, the independent variable will be the calculator or computer/calculator combination given to the two groups.
The dependent variable will be the speed at which each group finished solving the math problems.
The constant variable will be all other variables supplied to the two groups.
