the location the underwear was buried
constant
independent variable
dependent variable

Explanation:

1. The change in the underwear after 3 months is what is being measured and depends on other factors, so it's the dependent variable.
2. The brand of underwear is kept the same throughout to ensure consistency, making it a constant.
3. The amount of time (3 months) is set and not changed by other factors in the experiment, so it's a constant.
4. Brand - new underwear that has not been buried is used for comparison, so it's the control.
5. The location the underwear was buried can be changed and affects the outcome, so it's the independent variable.

Answer:

the change in the underwear after 3 months - dependent variable
the brand of underwear - constant
the amount of time (3 months) - constant
brand new underwear that has not been buried - control
the location the underwear was buried - independent variable
