I feel very controversial about this website at the moment.. I believe that it is very unfair for people to take their time and effort to answer question for students struggling in different topics and receive no benefits in return. It feels like we are basically doing their work for free.... I have helped a couple of students and got to the second place on the leaderboard and did not receive the $10. How do you guys feel about this?

A student is conducting their science experiment on the effect of caffeine on dogs. He has 3 groups of test subjects. The 1st group of dogs receives plain water. The 2nd group of dogs receives 10 mg of caffeine each, and the 3rd group receives 50 mg of caffeine each. He will measure their activity levels by recording how long each dog runs without stopping, after giving them the pills. What is the dependent variable in this experiment?
