most explanations here suggest that choice C seems to support the first explanation (beetle gets tired) rather than the second explanation (beetle is unable to process rapidly changing visual info and goesblind).
Choice C - "C. The beetles maintain a fixed time interval between pauses, although when an insect that had been stationary begins to flee, the beetle increases its speed after its nextpause."
However, if a beetle was indeed pausing due to getting tired, then shouldn't we expect the intervals between pauses to go down, (rather than remain fixed) or the frequency of pauses to go up. Also, that it can increase it's speed after a pause would suggest that it didn't pause due to being tired (if that were the case, surely the speed after a pause should be lower to speed before the pause).
So I believe that it undermine the tiredness explanation.
Although I do fail to see how this option strengthens the rapidly changing visualsexplanation.
