Which conclusion can be drawn from the map about the Portuguese and Spanish trade situation in the 16th century? The primary goal of both Spain and Portugal was finding silver. The two nations carved out different trading spheres in Latin America, Africa, and Asia. Portugal at the time was a wealthier nation than Spain, though the situation later reversed. Both Spain's and Portugal's exploration efforts were funded by the pope.

The Zimmerman Note was a note sent from Germany to Mexico asking Mexico to align itself with German interests. If the US entered the war and if Mexico opposed the US, the reward would be Arizona California and one other state -- perhaps Texas. It was a major contributor to the declaration of war on Germany by America.

The sinking of the Lusitania was another major event. When the Lusitania was sunk, 2000 people were affected.

Submarine warfare really aggravated the US. Many merchant ships were sunk.
