Question

submarines: what was the end result of the germans unrestricted submarine warfare? americans were outraged and joined wwi german subs owned and controlled the oceans allied ships refused to sail allied developed new technology to combat submarine warfare.

Explanation:

To determine the end result of Germany's unrestricted submarine warfare in WWI, we analyze each option:

• Option 1: Germany's unrestricted submarine warfare, especially incidents like the sinking of the Lusitania, outraged Americans. This outrage contributed to the US joining WWI. This is historically accurate.
• Option 2: German submarines did not "own and control the oceans" as Allied forces countered them, so this is incorrect.
• Option 3: Allied ships did not refuse to sail; they continued operations with countermeasures, so this is incorrect.
• Option 4: While the Allies did develop technology to combat submarines, the most direct and impactful end result related to the broader war context (like US entry) was the outrage leading to US joining WWI. The question asks for the "end result" and the US entry was a major turning point.

Answer:

A. American's were outraged and joined WWI
