Question

Options

• The attack on Pearl Harbour

• The assassination of Archduke Francis Ferdinand

• The sinking of Lusitania by U-boats

• None of the above

Answer 1

The sinking of Lusitania by U-boats

Explanation:

In 1915, a German submarine (U-boat) sank the British ocean liner Lusitania, killing more than 1,200 people, including over 120 Americans. This event caused outrage in the United States, increasing anti-German sentiment. Although the U.S. didn’t enter the war immediately, the attack played a major role in shifting public opinion, leading to America’s formal declaration of war against Germany in 1917.
