Hi. I am not sure if there should be a question or missing details in your post. I searched these statements and it looks like this is an essay made by Barbara W. Tuchman regarding how the United States entered the World War I. This was written last April 1967 during the 50th anniversary of America entering the Great War.

The correct answer to this open question is the following.
The role did the Oregon issue played in the 1844 presidential election was the following.
The Democratic party insisted that the United States had a genuine claim to demand Oregon as part of the US. At that time, the British controlled Oregon. This issue met the other territorial expansion demand: the annexation of Texas to the Union. That is why the Democratic candidate James Polk included in his platform the expansionist idea that later became the Manifested Destiny, the right of the US to expand and grow. Polk won the presidency by defeating Henry Clay, who opposed the annexation of Texas.
Democrats hosted mass rallies, parades, and barbecues to star up popular support and also to foster intense party loyalty. In both periods there was a high voter turn out often between 80-90 percent and there was fierce competition with the republicans over economic ideologies with democrats favoring free trade while the republicans favored protectionist policies.
Federal funds for internal improvements was one idea that Andrew Jackson did not support. The correct option among all the options given in the question is the third option. He did want to make an exception if there was any express grants. Jackson was ready to overlook the interpretation he made.
