Had to look for the missing options and here is my answer.
The foreign crisis that is being described above is the one in Haiti. This is when President Clinton committed U.S. troops to be the leader of a multinational force in order to regain a democratically elected president. This also led to sending former president Carter to be the one who will negotiate. Hope this helps.
For the assassination of Archduke Franz Ferdinand, one country was blaming another and all of these other countries got involved based on the alliance system because they were "helping" their alliance.
