Many ecologists have long argued that the elaborate warning calls of certain avian species when predators approach are altruistic, intended to alert others of danger. However, recent evolutionary models suggest that these vocalizations are primarily selfish actions meant to startle the predator or deflect attention; thus, any protective effect on the rest of the flock is entirely _______

Which choice completes the text with the most logical and precise word or phrase?

  1. A
    intentional
  2. B
    vital
  3. incidentalCevap
  4. D
    primary

Cevap

incidental
The correct answer is the word that means happening as a minor accompaniment or by chance in connection with something else. The text contrasts the long-standing belief that warning calls are altruistic with recent evolutionary models suggesting they are actually selfish actions meant to startle predators or deflect attention. Therefore, any protective benefit to the rest of the flock is not the primary purpose but rather a secondary, unplanned consequence. The word that precisely captures this meaning of being a secondary or accidental byproduct is 'incidental'.

Adım Adım Çözüm

1
Analyze the context and contrast in the passage.
The passage begins with a traditional view (warning calls are 'altruistic' and 'intended to alert others') and introduces a counterpoint with 'However'. The counterpoint states that the calls are 'primarily selfish actions' meant to 'startle the predator or deflect attention'.
Understanding the shift from intentional altruism to selfish utility helps determine the relationship between the calls and the protective effect on other birds.
2
Determine the relationship between the call's selfish purpose and the resulting protection of other birds.
Since the caller's main objective is self-preservation (selfish), any protection others receive is not the primary intent. It is an unintended, secondary byproduct.
To select the most logical and precise word to fill the blank, which describes the nature of this secondary protective effect.
3
Evaluate the choices to find the word that means secondary, accidental, or occurring as a byproduct.
'Incidental' means occurring by chance in connection with something else or as a minor accompaniment. This fits the context perfectly.
To choose the option that is semantically and grammatically correct.
