contribute to Congress's decision to declare war on Germany?
Shared German ancestry
The sinking of the Lusitania
Germany's submarine warfare
The Zimmerman note

Answer 1

Shared German ancestry did not contribute to Congress' decision to declare war on Germany.

Step-by-step explanation:

The United States remained neutral for much of World War I, until on April 2, 1917, the American government decided to declare war on Germany.

The main motivations for this were, on the one hand, the unscrupulous submarine warfare carried out by Germany against the Allies as well as any other ship that would trade with them (putting American merchant ships in danger) and, within this, especially the sinking of the Lusitania, a British ship but whose passengers were mostly United States citizens, in 1915.

On the other hand, the interception of the Zimmermann Telegram in early 1917, where Germany urged Mexico to attack America, ended up tipping the balance and urging the American government to declare war on Germany.
