In a forest often visited by the residents of a small town

[BTGmoderatorDC]

In a forest often visited by the residents of a small town bordering it, a plant was discovered that is believed to have been accidentally introduced by colonialists who tried to grow foreign vegetables in the area. The plant carries a potent neurotoxin, and upon digestion is capable of killing small to medium-sized animals. To cease the dwindling population of a small deer species that populates the forest, authorities are planning to erect explanatory signs at all the main entrances to the forest pleading to visitors to uproot and dispose of any such plants if identified.

Which of the following, if true, provides the most solid reason to expect that the authorities' plan will succeed?

A) A glass recycling project that was initiated by the authorities of the town had very successful results primarily because of the enthusiastic cooperation of the townspeople, who were offered small monetary incentives.

B) The elimination of the plants is imperative since the sap carrying the active neurotoxin that can be absorbed by the skin, oozes from picked leaves and results in cardiac symptoms, often fatal to humans.

C) The emblem of the town, a yellow and cobalt blue coat of arms, has in its center a stylized image of the deer species that inhabits the forest, and appears on municipal buildings, statues, and documents.

D) Continuing an age-old tradition started by the founders of the town, many townspeople engage in the breeding of dogs and can often be seen strolling the vicinity with two or three of their prized animals.

E) Mysterious to foreigners, the forest is a territory well-known to the townspeople, who as youths often wander through it, becoming familiar with the countless hidden paths leading into it.

We need to find what will determine if the authorities plan will succeed.
Premise: Plants that carries a potent neurotoxin and upon digestion is capable of killing small to medium-sized animals.

OPTION A - INCORRECT
This is completely outside the scope of the argument. The major concern of the argument is about a plant capable of killing animals and not a glass recycling project.

OPTION B - INCORRECT
We are concerned about how these neurotoxins kill small and medium-sized animals and not low it is fatal to humans.

OPTION C - INCORRECT
The argument is not about the emblem of the town.

OPTION D - INCORRECT
Breeding of dogs is not a solid reason to expect that the authorities plan will succeed because they cannot uproot or dispose the plants in question.

OPTION E - CORRECT
If a lot of the townspeople wander through the forest, it means that there is a higher chance for them to see plants and dispose them. This shows that the authorities plan will succeed.
