Difficulty: EasyPart-to-Whole Rhetorical Function

Beavers construct dams to create ponds, which protect them from predators. These dams are built using tree branches, mud, and stones. The deep water of the resulting pond allows beavers to build their lodges with underwater entrances, ensuring that wolves and bears cannot easily reach them. Consequently, these structures are vital to the beavers' survival in the wild.

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

  1. It details the specific materials used to construct the dams introduced in the first sentence.Answer
  2. B
    It outlines the main survival benefits that the dams provide against predators.
  3. C
    It states the primary argument that the passage as a whole attempts to prove.
  4. D
    It suggests that beavers prefer using stone over other materials when predators are nearby.

Answer

It details the specific materials used to construct the dams introduced in the first sentence.
The correct answer correctly identifies that the underlined sentence provides details about the physical components used to build the dams mentioned in the first sentence. By stating that the dams are made of 'tree branches, mud, and stones,' the sentence functions to elaborate on the construction of the structures introduced immediately before it.

Step-by-Step Solution

1
Analyze the underlined sentence and its immediate context.
The underlined sentence states: 'These dams are built using tree branches, mud, and stones.' It directly follows a sentence introducing beaver-constructed dams.
Understanding the content of the sentence and how it connects to the surrounding sentences is necessary to determine its rhetorical function.
2
Determine the relationship between the underlined sentence and the preceding text.
The preceding sentence introduces the concept of beavers building dams, and the underlined sentence specifies the physical components (branches, mud, stones) used to construct those dams.
This establishes the objective logical relationship of part-to-whole function.
3
Evaluate the choices to find the one that accurately describes this relationship.
The option stating that the sentence details the specific materials used to construct the dams introduced in the first sentence is correct, while the other options either confuse the sentence's function with other parts of the text, misidentify it as the primary purpose of the passage, or make speculative assumptions.
Identifying the correct description of the sentence's function leads to the correct option.
