The arctic fox was once the most common fox on the Northern Island. Recently, the number of red fox on the island surpassed, for the first time, that of the arctic fox. Nonetheless, both foxes eat the same prey and share the same environment.
Which of the following, if true, could best account for the decrease in arctic fox relative to the red fox?
(A) The red fox is able to digest food faster than the arctic fox can
(B) The polar bear, the arctic fox’s primary predator, has become increasingly less common on the island.
(C) On the most northern part of the island, the number of arctic fox still exceeds the number of red fox.
(D) Because the arctic fox tends to live longer than the red fox, a greater percent of arctic fox are able to procreate than are the red fox.
(E) As a result of increased temperatures, much of the snow that had provided camouflage to the arctic fox is now gone.

Lets analyze each option.
(A) The red fox is able to digest food faster than the arctic fox can.
So, the thinking can be- red fox digest food faster, meaning the arctic fox is relatively slower, meaning red fox gets hungry quicker and eats more again. That doesn't mean anything about the surpassing of red fox's total population over that of arctic fox. Also, since in the premise, the surpassing is mentioned to have taken place 'Recently', this means its due to some recent happening. Red fox did not recently changed its speed of digesting food, it must have always been the case. so A is eliminated.
(B) The polar bear, the arctic fox’s primary predator, has become increasingly less common on the island.
This option rather suggests population of arctic fox should have increased as its predator has become less common. So B is eliminated.
(C) On the most northern part of the island, the number of arctic fox still exceeds the number of red fox.
This fact doesn't provide any help on why the total population of red fox has recently surpassed the total of arctic fox. So, C is eliminated
(D) Because the arctic fox tends to live longer than the red fox, a greater percent of arctic fox are able to procreate than are the red fox.
Again, a fact that is not some recent happening. This must be true for all times and as a result the population of red fox must never haver surpassed that of arctic fox. Doesn't serve our conclusion.So, D is eliminated.
(E) As a result of increased temperatures, much of the snow that had provided camouflage to the arctic fox is now gone.
This gives a reason to believe that due to a change, like increased temperature, the camouflage of the arctic fox is gone, making them more exposed to predators or other threats. It gives a good cause of why the population became less than that of red fox. So, E is our answer.

It explains reason why despite both the foxes eating the same prey and sharing the same environment, the snow that provides camouflage leading to a decrease in the arctic foxe's population.
