Answer:
The correct answer would be - the number of times the student was able to squeeze the clothespin or rate of clothespin squeezing.
Explanation:
The dependent variable is the variable that depends on the change in the independent variable and measured or needs to be found in a scientific experiment or investigation.
In this experiment, the independent variable would be an exercise to found the effect on the change of the rate of clothespin squeezing or the number of times the students are able to squeeze the clothespin.
Thus, the correct answer would be - the rate of clothespin squeezing.

Observations
Through natural selection it happened over many generations and it was gradual, not a sudden change in the founder species. One bird was randomly born with a fatter beak and so could eat a seed that was harder to crack, this meant he lived longer than the other birds or was fitter, so bred more and so more of the offspring had this slightly larger beak. This continued and the birds moved to the islands with their ideal seed and kept getting fatter beaks etc until they were no longer the same species (this is when they can't breed to produce fertile offspring).
