Wolves, when hunting in packs, factor in many conditions that will affect the hunt and that can tip the scales in their favor. In snow-fed winters, the wolf pack trails the herd of caribous for days till one of the animals realizes the fact, panics, tries to run and falls prey in the attempt. In warm weathers, the same pack changes its tactics; they start chasing the prey over the hard ground as soon as they spot them. It is likely that the weather-induced changes in the terrain bring about the changes in the hunting tactics of the wolves.
Which of the following, if true, provides the strongest support for the explanation offered?
A.Cold winters make wolves hungrier than usual as they need more energy to keep themselves warm under those harsh conditions.
B.The number of wolves in a pack is typically lower during the warm weather.
C.The cold air during winters is denser and harsher on the eyes, possibly slowing down the aggressive nature of the predators.
D.A herd of caribous is typically quite cautious of any possible wolf packs that could be trailing them with the intent to hunt.
E.The wolves have wide round paws that have evolved to perform like snowshoes whereas the caribous with their hoofed feet can outrun even the fastest wolf over wide plains if they have a good start.
Hi
VeritasKarishma.
I am quite confused on the OA for this question.
I feel the answer should be C.
THe OA is E.
My reasoning:
Weather induced changes in terrain causes changes in tactics of wolves.
C.The cold air during winters is denser and harsher on the eyes, possibly slowing down the aggressive nature of the predators.
In winters they are not aggressive because of the difficult terrain, whereas we can infer that in warm weathers, they will be aggressive.
Hence in Warm weather, they start catching the prey as soon as they see one.
whereas in winter, due to harsh conditions, they patiently wait and follow their prey.
E.The wolves have wide round paws that have evolved to perform like snowshoes whereas the caribous with their hoofed feet can outrun even the fastest wolf over wide plains if they have a good start.
This option tells me that the wolves and the prey have evolved in accordance with the weather to survive.
Now from this point on I can't make the connection between how the weather induced changes in the TERRAIN affect the hunting patterns?
Looking forward to your reply.
