Scientists base many of their investigations on questions that test accepted theories. Which outcome of an investigation would cause a scientist to ask a different question? A: The observed results are different from the expected results.
B: The investigation had many sources of error.
C: Another scientist proposed the same theory.
D: The expected results could be explained in different ways.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
