Zorluk: ZorSupporting Claims with Evidence and Details

[1] In 1912, geophysicist Alfred Wegener proposed the theory of continental drift, claiming that Earth's continents were once united as a single supercontinent. [2] To support this claim, Wegener pointed to matching geological formations and fossil records on opposite sides of the Atlantic Ocean. [3] For instance, fossils of the freshwater reptile Mesosaurus are found only in southern Africa and eastern South America. [4] The writer wants to add a sentence after sentence 3 to provide specific, concrete geological evidence that supports the claim that these two continents were once physically connected.

Which of the following sentences best achieves this goal?

  1. In addition, the ancient mountain ranges of the Cape Fold Belt in South Africa align perfectly in structure and rock type with the Sierra de la Ventana range in Argentina.Cevap
  2. B
    Other scientists have also found various kinds of rocks and mountains that look similar in different countries.
  3. C
    Wegener's ideas about these geological connections were detailed in his 1915 book, which was widely read but heavily criticized.
  4. D
    These matching mountain ranges are crucial; because they provide the physical proof of a prehistoric connection.

Cevap

The sentence that names specific mountain ranges (the Cape Fold Belt and the Sierra de la Ventana) and describes their structural alignment.
The correct option provides specific, concrete geological evidence by naming the Cape Fold Belt in South Africa and the Sierra de la Ventana range in Argentina, demonstrating how they align in structure and rock type to support the claim of a physical connection.

Adım Adım Çözüm

1
Analyze the prompt to identify the specific rhetorical goal.
The goal is to find a sentence that provides specific, concrete geological evidence supporting the claim that Africa and South America were once physically connected.
Understanding the precise requirement prevents choosing options that are too general or off-topic.
2
Evaluate each option against the criteria of being specific and concrete.
The option referencing the Cape Fold Belt and Sierra de la Ventana provides specific named geological features and structural alignment, whereas the option mentioning 'rocks and mountains in different countries' is too general.
This filters out vague or general statements that fail to meet the rhetorical goal.
3
Check the relevance of factually true options.
The option about Wegener's 1915 book is factually true but does not provide direct geological evidence of the connection.
This avoids the distractor that is relevant to the topic of Wegener but irrelevant to the specific claim.
4
Inspect remaining options for grammatical correctness.
The option ending with 'crucial; because they provide...' contains a semicolon fragment error, while the correct option is grammatically sound.
ACT English questions require the correct answer to be both rhetorically effective and grammatically correct.
