Answer:
Lead to less money and trading opportunities.
Step-by-step explanation:
Despite the world power engaging a war against each other, the United States had fairly managed to stay out of it. This means that the US remained a neutral nation, supporting neither of the sides in the war.
America was sure that if it remained a neutral nation amidst the ongoing war, it will be able to continue with trade deals with other nations. To them, taking sides will be detrimental to the nation's trade economy. If it has to take a side, then that will probably lead to a loss in their financial profit and reduce any trading opportunity.
But with the attack of an American passenger cruise by German submarines, the United States decided to enter the war against Germany. So, despite the war starting in 1914, the United States only joined the war in 1917, three years after the start of the war one year before it ended.
Thus, the correct answer is the second option.
