First question: he started making alliances after coming to power and a war did happen, so we have to choose amog the two other options:
give powerful and persuasive speeches
create industry and employment where none existed
I find that they're both true and that an even better answer would be that he gave people huge promises of making Italy great again.
If I can choose only one option, then "speeches" is better, since the other one required him to be in power already to do
second question: while the last option did happen, as minorities were persecuted, the major mechanism of keeping the population in control was controlling resistance, so the correct answer is the first one.
World war 1 broke out in 1914 because a group of Serbian nationalists (The Black Hand) assassinated the duke of Austria-Hungary. Austria -Hungary threatened Serbia with a bunch of wishes that they wanted Serbia to due for them. Due to the treaty between Serbia and Russia, Serbia said no. Germany, who had a treaty with Austria-Hungary threatened to attack if Russia mobilized its army. Russia did and Germany invaded Belgium. This brought Great Britain and France into the war.
The most important result the came from Ww1 was the treaty of Versailles in 1919. this became a catalyst to wwii because Germany was forced to pay reparations to the Allies.
It helped them buy seeds, tools and supplies in bulk
