Question

Difficulty: MediumAnalogous Relationships

In evolutionary biology, Batesian mimicry describes a relationship where a harmless species, the mimic, gains protection from predators by sharing the warning signals of a noxious species, the model. For instance, the harmless milk snake displays the same red, yellow, and black banding pattern as the highly venomous coral snake. Predators that have had a painful encounter with a coral snake learn to avoid any creature with this distinct coloration. Consequently, the milk snake enjoys a survival advantage. However, this protection is entirely dependent on the predator's prior experience with the model; if the mimic population becomes too numerous relative to the model, predators will discover that the warning pattern does not reliably indicate venom, neutralizing the mimic's defense.

Based on the passage, the relationship between the mimic and the model is most analogous to which of the following scenarios?

  1. A
    A venomous predator adopts the physical markings of a harmless herbivore to approach prey without causing alarm, though this tactic fails if the prey eventually learns to detect the predator's scent instead of relying on sight.
  2. B
    A manufacturer produces a low-cost imitation of a luxury designer watch to appeal to budget-conscious buyers. The imitation succeeds by offering status at a fraction of the cost, but the luxury brand suffers financial losses as its market share declines.
  3. A new, unrated financial firm uses branding elements similar to an established, highly secure bank to win client trust. This strategy succeeds because clients associate those visual cues with reliability, but it fails if too many unstable firms copy the brand, causing clients to realize the cues no longer guarantee security.Answer
  4. D
    A species of bird develops bright, highly visible plumage to attract mates in a dense jungle canopy, but the striking colors also make the bird highly visible to predators, thereby limiting its population growth.

Answer

The correct answer describes a new financial firm that copies the branding of an established bank to gain client trust, a benefit that is lost if too many unstable firms copy the strategy.
The correct answer parallels Batesian mimicry. The unrated firm acts as the mimic, copying the cues of the secure bank (the model) to avoid client skepticism (predation). This strategy relies on the cues remaining a reliable sign of safety, a benefit that is lost if too many copycats dilute its meaning.

Step-by-Step Solution

1
Analyze the core logical structure of the relationship in the passage.
The relationship is one where a weak/harmless entity (mimic) copies the signal of a strong/dangerous entity (model) to gain protection from a selector (predator). This benefit is contingent on the signal remaining reliable, which fails if too many mimics copy the model.
Identifying analogous relationships requires extracting the structural rules of the scenario while ignoring the specific biological context.
2
Evaluate the options against the extracted logical structure.
The scenario involving the financial firm perfectly matches all criteria: the unrated firm (mimic) copies the branding (signal) of the secure bank (model) to avoid client skepticism (predator). The strategy fails when over-copying dilutes the reliability of the signal.
The correct option must parallel the source scenario in structural terms, including the condition under which the strategy fails.

Key Concept

Identifying analogous relationships requires abstracting the logical structure of a scenario in the text and matching it to a new scenario with different details.
