Analyze the question and options

The question asks which statement is best supported by a map showing US territorial expansion during the 1800s. Although the map itself is not visible in the cropped image, the options describe standard historical interpretations of 19th-century US territorial growth. We can evaluate the historical accuracy of each option to determine the correct answer.

Evaluate the historical claims

• Option (1) states that territorial expansion during the 1800s was achieved through a variety of methods. This is historically accurate, as the US acquired land through purchase (Louisiana Purchase, Gadsden Purchase), treaty/negotiation (Oregon Territory), annexation (Texas), and war (Mexican Cession). A map of US territorial acquisitions typically labels these different methods.
• Option (2) is incorrect because expansion continued extensively after the Louisiana Purchase (1803).
• Option (3) is incorrect because the annexation of Texas (1845) directly contributed to the outbreak of the Mexican-American War.
• Option (4) is incorrect because the Great Plains were not the last area settled; coastal areas like California and Oregon were settled heavily during the Gold Rush and Oregon Trail migrations before the interior plains were fully settled.

Connect to mastered concepts

Using the Westward Expansion and US Territorial Acquisition knowledge points, we recognize that standard historical maps of US expansion illustrate the diverse methods of acquiring land (treaties, purchases, annexations, and military conquests) across the 19th century. Therefore, option (1) is the best-supported statement.

Answer:

• (1) Territorial expansion during the 1800s was achieved through a variety of methods. (Correct answer)
• (2) Colonial goals had been realized once the Louisiana Purchase was complete.
• (3) The annexation of Texas was an effort to avoid war with Mexico
• (4) The Great Plains was the last area settled
