Answer:
1. Nationalism
2. Serbian
3. Stalemate
4. U boats
5. Armistice
Step-by-step explanation:
During the 1900's militarism and Nationalism, extreme pride in ones country were spreading throughout Europe causing conflicts between nations. Things came to a head when a Serbian nationalist assassinated the heir to the Austrian throne. This caused the start of World War 1. During the war the fight on the Western Front turned into a long deadly Stalemate, a deadly lock that neither side could break. Germany used U bombs to bomb the English Coast. Eventually the fighting got so bad that the Germans saught a Armistice, which is a peace treaty with allies.
For many of these blanks we can simply use our context clues as well as a dictionary to find.
For the first blank, the phrase following it, "extreme pride in one's country" can be a reference to the blank meaning that this phrase is likely correlated to what must be in the blank . Based on the answer choices, the answer that relates to this definition most closely is nationalism which means loyalty or devotion to one's nation. This makes perfect sense as we are referring to people who have "extreme pride" for their nation.
For the second blank, we must analyze the whole phrase and use the context to find the answer. The phrase says, "Things came to a head when a _____ nationalist assassinated the heir to the Austrian Throne. In order to find this blank we must do a little research. We can begin by searching up who was the heir to the Austrian Throne before world war 1. Many sources indicate that Archduke Franz Ferdinand was the heir of the Austrian Throne. We can next search who assassinated Archduke Franz Ferdinand. Many sources indicate that Archduke Franz Ferdinand was assissinated by Gavrilo Princip, a Bosnian-Serbian nationalist. So the person who assassinated the heir of the Austrian throne was a Serbian nationalist.
For the third blank, we are given more context clues based on the following phrase, "a deadly lock that neither side could break". This phrase is most closely related to Stalemate, which is a term often used in chess where a player who is not in checkmate can make no legal move and therefore results in a draw. This term can be related to the part of the war as neither of the two powers fighting on the western front could not advance.
For the fourth blank, we use the context given, "bombing on the east coast." The two answers that are most related to this are U boats and Zeppelins. Both were use as weapons of destruction by the Germans however, U boats were submarines with torpedoes. These were used to take out enemy ships that carried supplies on the east coast. Zeppelins were airships with bombs that initially going to be used to bomb the east coast but as a result of a storm had to move towards the western coast. So the most logical answer here is U boats.
For the last blank we can use the following phrase, a peace treaty with the Allies. This answer choice is most closely related to Armistice which means An agreement between two opposing armies in order to end hostility and discuss peace which is also known as a treaty or truce.
