2. Germany declared war on Russia after Russia pledged to support Serbia
3. All of the above
4. None of the above

Answer 1

To determine which statements are incorrect, let's analyze them:

1. Austria-Hungary blamed Serbia for the death of Franz Ferdinand, after which Russia supported Serbia.
   This statement is correct. The assassination of Archduke Franz Ferdinand in June 1914 by a Bosnian Serb nationalist led Austria-Hungary to blame Serbia, prompting Austria-Hungary to issue an ultimatum to Serbia. Russia, which had Slavic ties to Serbia, supported Serbia in the conflict.

2. Germany declared war on Russia after Russia pledged to support Serbia.
   This statement is also correct. After refusing to demobilize its forces in response to Austria-Hungary’s declaration of war against Serbia, Germany declared war on Russia on August 1, 1914.

Given that both statements are correct:

• Answer: 4. None of the above (none of the statements are incorrect).
