Zorluk: OrtaRhetorical Synthesis: Summarization and Generalization

While researching bioacoustics, a student takes the following notes:
* Blue whales (*Balaenoptera musculus*) use low-frequency vocalizations to communicate across vast ocean distances.
* In a 20182018 study, researchers analyzed underwater audio recordings of blue whale songs collected from 19601960 to 20182018.
* The analysis revealed that the fundamental frequency of blue whale songs has decreased by approximately 30%30\% globally.
* Researchers hypothesize that this pitch reduction is an adaptation to cope with rising ambient ocean noise caused by commercial shipping.

The student wants to summarize the study's findings. Which choice most effectively uses information from the given notes to accomplish this goal?

  1. An analysis of audio recordings from 19601960 to 20182018 revealed that blue whales have reduced the pitch of their songs by about 30%30\% globally, likely to communicate over rising shipping noise.Cevap
  2. B
    To investigate marine communication, researchers in a 20182018 study analyzed underwater audio recordings of low-frequency blue whale vocalizations collected over a span of nearly sixty years.
  3. C
    Blue whales produce low-frequency vocalizations to communicate, which are vulnerable to ambient ocean noise caused by commercial shipping vessels.
  4. D
    Increasing commercial shipping noise since 19601960 has disrupted the communication networks of all low-frequency marine mammals, forcing them to alter their migration paths.

Cevap

The choice stating that an analysis of recordings from 19601960 to 20182018 revealed a global pitch decrease of about 30%30\%, likely to communicate over shipping noise, is correct because it summarizes both the finding and its hypothesized cause.
The correct answer effectively summarizes the findings of the study by stating that the analysis of recordings from 19601960 to 20182018 showed a global 30%30\% reduction in the pitch of blue whale songs, and by presenting the hypothesis that this change helps them communicate over shipping noise.

Adım Adım Çözüm

1
Identify the student's specific rhetorical goal in the prompt.
The goal is to summarize the findings of the 2018 study.
Understanding the exact goal helps eliminate choices that focus on background context or methodology rather than the results.
2
Analyze the notes to determine what findings the study produced.
The findings are that blue whale songs have decreased in pitch by approximately 30%30\% globally, which is hypothesized to be an adaptation to shipping noise.
Knowing the specific findings allows for comparison with the options to see which one accurately presents this information.
3
Evaluate the options to find the one that summarizes these findings without adding outside information or ignoring the goal.
The option mentioning the 30%30\% reduction in pitch and the shipping noise explanation is the only choice that directly summarizes the findings.
This choice satisfies the rhetorical goal, while others either focus on methodology, background information, or make unsupported claims.
