Question

as a result of the spanish - american war, the united states saw the need to build the panama canal because
new colonies had been acquired in africa
spanish opposition to the canal had ended
the united states navy could then move more quickly between oceans
united states railroads could not transport enough manufactured goods

Explanation:

After the Spanish-American War, the U.S. gained overseas territories across both the Atlantic and Pacific. A canal through Panama allowed the U.S. Navy to shift ships rapidly between the two oceans, a critical strategic need for protecting its new global interests. The other options are incorrect: the U.S. acquired no African colonies from the war; Spanish opposition was not the driver; railroad capacity was not the core reason for the canal.

Answer:

the United States navy could then move more quickly between oceans
