C] the beetle maintains fixed time interval b/w pauses---this helps us to think that beetle is not tried, otherwise the frequency or duration of pauses would increase,this will weaken the tiredness hypothesis

, although when an insect that had been stationary begins to flee, the beetle increases its speed after its next pause.---may be this points out to the fact that beetle can increase it speed ONLY after it has adjusted the visual filed ie after its next pause. this will strengthen the eye problem hypothesis

more thoughts please

The answer to question posted by me is C.

The problem for the beetle seems to be at the start of the chase , with regard to speed. So when after being stationary it starts moving there is an abrupt change in visual information which it is not able to process properly and results in lower speed. The difference between being stationary and the pauses is that in the latter it is still processing the previous information and as that happens in a moment it starts chasing again and there is a sort of continuity and not an abrupt change in the visual information even after the pause. So it can move at a higher speed after the first pause.

can you please provide a definitive answer to the question?
Is the question wrong?

Tiger beetles are such fast runners that they can capture virtually any nonflying insect. However, when running
toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack. Perhaps they
cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while
running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go
blind and stop. Which of the following, if discovered in experiments using artificially moved prey
insects, would support one of the two hypotheses and undermine the other?
A. When a prey insect is moved directly toward a beetle that has been chasing it, the beetle immediately turns and
runs away without its usual intermittent stopping.
B. In pursuing a moving insect, the beetles usually respond immediately to changes in the insect's direction, and
pause equally frequently whether the chase is up or down an incline.
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 next pause.
D. If, when a beetle pauses, it has not gained on the insect it is pursuing, the beetle generally ends its pursuit.
E. When an obstacle is suddenly introduced just in front of running beetles, the beetles sometimes stop
immediately, but they never respond by running around the barrier.

Though the same stimulus is available with different answer choices, I found this one to be a tough one. Explanations will be appreciated.
