Zorluk: OrtaRhetorical Structure and Sentence Function

Read the passage below:

For decades, archaeologists analyzing ancient Mesoamerican agriculture relied primarily on macrobotanical remains, such as charred seeds and wood fragments, to reconstruct prehistoric crop cultivation. However, this approach systematically underestimated the significance of root crops like cassava and sweet potato, which rarely preserve in acidic tropical soils. To address this evidentiary bias, recent investigations have increasingly deployed phytolith analysis—the microscopic examination of silica bodies deposited within plant tissues. Critics initially contended that phytolith morphotypes are insufficiently distinct to differentiate closely related domesticated species from their wild progenitors. Yet, advanced three-dimensional morphometric modeling has recently demonstrated that phytoliths from domesticated maize can indeed be statistically distinguished from wild teosinte. Consequently, microbotanical analysis has shifted from an auxiliary diagnostic tool to a cornerstone of paleoethnobotanical methodology.

Which of the following best describes the rhetorical function of the sentence 'Critics initially contended that phytolith morphotypes are insufficiently distinct to differentiate closely related domesticated species from their wild progenitors' in the context of the passage as a whole?

  1. It introduces an objection to a newly introduced methodology that the author subsequently shows has been addressed by subsequent technological advances.Cevap
  2. B
    It provides empirical evidence that undermines the author's main assertion regarding Mesoamerican agricultural history.
  3. C
    It summarizes the central argument underpinning traditional macrobotanical research frameworks.
  4. D
    It qualifies the author's endorsement of three-dimensional morphometric modeling by highlighting its methodological limitations.
  5. E
    It proves conclusively that microbotanical remains are superior to macrobotanical remains in acidic soil environments.

Cevap

The sentence functions to introduce a potential objection or limitation concerning phytolith analysis, which the author immediately counters in the subsequent sentence by citing advances in three-dimensional morphometric modeling.
The sentence introduces a challenge raised by critics regarding the diagnostic utility of phytolith analysis. The author follows this sentence with the contrast word 'Yet' to show how 3D morphometric modeling resolved this exact limitation, making the option stating that it introduces an objection subsequently shown to be addressed by technological advances the correct description of its function.

Adım Adım Çözüm

1
Analyze the structural position of the target sentence
The target sentence comes immediately after the passage introduces phytolith analysis as a new technique to solve macrobotanical bias.
Understanding what precedes the sentence establishes what method is being discussed.
2
Examine the sentence content and transition words that follow
The sentence notes that critics argued phytolith morphotypes were not distinct enough. The next sentence begins with the contrast word 'Yet' and explains how 3D morphometric modeling resolved this issue.
Tracking pivot words reveals whether the objection is accepted or refuted by the author.
3
Determine the overarching rhetorical role
The sentence sets up a obstacle/criticism to a new technique that is subsequently overcome by technological innovation.
Connecting the sentence to both preceding and succeeding sentences clarifies its function within the paragraph's argument.
