A student is writing a social studies report for class. Read the paragraph from the student report and answer the question that follows.

Question

After the Louisiana Purchase, the territory of the United States increased by a lot. The land gained stretched from the Mississippi River to the Rocky Mountains and from the border of Canada to the Gulf of Mexico, and meant that the Unites States controlled twice as much territory as it did before 1803. The purchase was an important achievement of President Jefferson.

The student wants to replace the underlined phrase with something more precise. Which replacement BEST fits the author’s intended purpose and audience?

A.
was added to

B.
became much bigger

C.
grew

D.
doubled

Answer 1

The replacement that BEST fits the author’s intended purpose and audience is:

D. doubled

This option is precise and clearly conveys the significant increase in territory as a result of the Louisiana Purchase, aligning well with the formal tone of a social studies report.
