Question #N663

While many of these structures were built by the Romans, some were also built by the Etruscans, a people that lived in central Italy before the Romans. Because of their shared construction, it is difficult to tell these structures apart. Both types of structures are built from local stone, and both types of structures were built with a similar design. For example, the walls of both types of structures were built with a similar thickness and the roofs of both types of structures were built in a similar style.

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

A. It provides an example that explains why it’s difficult to tell Roman structures and Etruscan structures apart.

B. It describes the way in which the Romans built their structures.

C. It establishes that the Romans and the Etruscans used different materials.

D. It suggests that Roman structures are better built than Etruscan structures.

Correct Answer is: A

The underlined sentence provides an example that explains how the Romans and Etruscans used similar materials and building styles, which makes it difficult to tell their structures apart. The sentence contrasts with the previous sentence, which mentions that the Romans built many of these structures, and provides an example to support the claim that both types of structures were built with similar designs. Choices B, C, and D are incorrect because they do not accurately describe the function of the underlined sentence.
