Zorluk: OrtaPart-to-Whole Rhetorical Function

Urban ecologists studying the behavior of songbirds in metropolitan areas have noted that some species, such as the great tit (*Parus major*), sing at higher frequencies in noisy environments than their rural counterparts do. This acoustic shift is widely assumed to be a direct, real-time adaptation to prevent songs from being masked by low-frequency traffic rumble. However, biologist Kenji Sato and his team discovered that great tits inhabiting quiet city parks also sing at higher frequencies than rural birds, despite facing minimal traffic noise. This finding suggests that the frequency shift may not be a simple response to immediate acoustic interference. Instead, the behavior might be a genetically fixed trait or linked to other urban factors, such as architectural barriers that affect sound propagation.

Which choice best describes the function of the underlined sentence in the text as a whole?

  1. A
    It describes a research methodology used by Sato's team to measure ambient traffic noise in city parks.
  2. It introduces empirical evidence that calls into question a common explanation for the acoustic behavior of urban songbirds.Cevap
  3. C
    It proposes an alternative hypothesis to explain why rural songbirds sing at lower frequencies than urban songbirds.
  4. D
    It states the primary conclusion of the passage regarding the genetic factors influencing songbird vocalizations.

Cevap

The choice that best describes the function of the underlined sentence is the one stating that it introduces empirical evidence that calls into question a common explanation for the acoustic behavior of urban songbirds.
The correct option correctly identifies the function of the underlined sentence as introducing empirical evidence (the discovery of high-frequency singing in quiet parks) that challenges the common assumption that this shift is a direct response to traffic noise.

Adım Adım Çözüm

1
Analyze the context before the underlined sentence.
The first two sentences state that urban songbirds sing at higher frequencies, and this behavior is widely assumed to be a real-time adaptation to avoid being masked by traffic noise.
To understand what assumption or idea the underlined sentence is reacting to.
2
Analyze the underlined sentence itself.
The underlined sentence states that great tits in quiet parks (where there is no traffic noise) also sing at higher frequencies.
To identify the direct rhetorical contribution of the underlined portion.
3
Evaluate how the underlined sentence functions in the text as a whole.
Since the birds sing at high frequencies even without traffic noise, this finding directly challenges the assumption that the pitch shift is simply a real-time adaptation to traffic noise. Therefore, the sentence introduces evidence that calls a common explanation into question.
To match the function to the correct option.
