Hello Sir,
So I did read your explanation and it makes sense to me. But just for full proofing the argument , can you tell me, based on your analysis, which hypothesis is undermined and which one is supported?
I know a similar question exists and for which OA is B. That one clearly undermines one and supports another one. But this one is confusing.
TheNightKingYes indeed it's a 750 level question, took 4 min to crack.
Let's look at two arguments :
the beetles intermittently stop, and then, a moment later, resume their attack. Why ?
a
.they cannot maintain their pace and must pause for a moment's rest or
b.
while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.Now let's look at option B
Quote:
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.
Here the statement undermines the both statement "a" and "b" mentioned above.
the beetles usually respond immediately to changes in the insect's direction-- This statement explains that beetles can process rapidly changing visual information, hence undermine
statement b.
pause equally frequently whether the chase is up or down an incline--This statement explains that no matter going up or down,beetles pause equally frequently.Thus taking rest is not the reason for pause and this undermines
statement a.
Now let's see option C.
Quote:
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.
although when an insect that had been stationary begins to flee, the beetle increases its speed after its next pause.As per above line if beetle increases its speed immediately then the statement would have supported statement B mentioned above. But that's not the case, beetle needs to stop to see the position of insect,hence this undermines
statement B.
the beetle increases its speed after its next pause- Why beetle have to take pause to increase its speed ?
Because beetle wanted to take rest hence it supports
statement A.
If beetle had increased its speed immediately after beetle started flying then this line would have undermine statement B also.
I hope it helps
