Difficulty: EasyRhetorical Synthesis: Comparison and Contrast

While researching prehistoric predators, a student took the following notes:

* *Giganotosaurus* was a theropod dinosaur that lived in South America during the Late Cretaceous period.
* *Giganotosaurus* is estimated to have reached lengths of 1212 to 1313 meters.
* *Tyrannosaurus rex* was a theropod dinosaur that lived in North America during the Late Cretaceous period.
* *Tyrannosaurus rex* is estimated to have reached lengths of 1212 to 1313 meters.

The student wants to emphasize a similarity in the size of the two dinosaurs. Which choice most effectively uses information from the given notes to accomplish this goal?

  1. A
    While *Giganotosaurus* lived in South America, *Tyrannosaurus rex* lived in North America.
  2. B
    *Giganotosaurus* and *Tyrannosaurus rex* were both theropod dinosaurs that lived during the Late Cretaceous period.
  3. Both *Giganotosaurus* and *Tyrannosaurus rex* are estimated to have reached lengths of 1212 to 1313 meters.Answer
  4. D
    Although *Giganotosaurus* reached lengths of 1212 to 1313 meters, *Tyrannosaurus rex* was much smaller.

Answer

Both *Giganotosaurus* and *Tyrannosaurus rex* are estimated to have reached lengths of 1212 to 1313 meters.
The correct choice successfully fulfills the rhetorical goal by stating that both *Giganotosaurus* and *Tyrannosaurus rex* are estimated to have reached lengths of 1212 to 1313 meters, which directly highlights a similarity in their size.

Step-by-Step Solution

1
Identify the student's specific goal.
The goal is to emphasize a similarity in the size of the two dinosaurs.
This helps target the correct comparison needed from the bulleted notes.
2
Find size information for both dinosaurs in the notes.
The notes indicate that both *Giganotosaurus* and *Tyrannosaurus rex* reached estimated lengths of 1212 to 1313 meters.
To base the size similarity on the factual details provided.
3
Evaluate the choices to see which one accurately compares these sizes as a similarity.
The statement expressing that both dinosaurs reached lengths of 1212 to 1313 meters successfully meets this criterion.
This is the only choice that emphasizes a similarity in size using correct facts from the notes.
