The correct answer is that publicity helped the Union in part <em>to finance the war</em> against the Confederacy.
Explanation:
Where the civil war started in 1861, the Union needed to finance its army requirements, so the main base to do this were the taxes by that time. However the income that came from the taxes were not enough, so that the government, led by Abraham Lincoln, started to<em> sell bonds </em>for the first time in small denominations directly to the people. All of this was capable in a selling system where <em>publicity</em> and <em>patriotism</em> were the key factors of it.
Because that was the only support they could really get, mainly because the government always sided with the factory owners because they were the ones making the money for them. <span />
