Dietary studies of the critically endangered mountain bongo show that its population decline correlates strongly with the loss of its preferred forage, a specific species of high-altitude bamboo. In an effort to reverse this decline, conservationists artificially replanted this bamboo species in several depleted habitats. However, bongo populations in those areas failed to recover. Botanists subsequently discovered that the replanted bamboo, though belonging to the exact same species as the original, was of a different subspecies. This replanted subspecies produces a bitter chemical compound that the bongos find unpalatable.

Based on the information above, the following statement is most strongly supported: Belonging to the mountain bongo's preferred species of bamboo is not a sufficient condition for a plant to be palatable to the mountain bongo.

Answer: Answer

Answer

The statement is True.
The stimulus explicitly establishes that there is a subspecies of bamboo that belongs to the bongo's preferred species but produces a bitter compound making it unpalatable. Since there is at least one instance where a plant is of the preferred species but is not palatable, belonging to that species cannot be a sufficient condition for palatability.

Step-by-Step Solution

1
Analyze the premises to identify why the mountain bongo populations failed to recover in the replanted areas.
The failure occurred because the replanted bamboo is unpalatable due to a bitter chemical compound.
Understanding the cause of the failure is essential to drawing correct inferences.
2
Identify the biological classification of the unpalatable replanted bamboo.
The text states that the replanted bamboo belongs to the exact same species as the preferred forage, but it is a different subspecies.
Tracking the exact scope of the categories (species vs. subspecies) prevents logical overreach.
3
Evaluate the logical truth of the provided statement based on the identified facts.
Because we have evidence of a bamboo plant that belongs to the preferred species but is unpalatable, it logically follows that belonging to the species is not sufficient to ensure palatability.
To determine whether the statement is strongly supported by the stimulus.
