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. 
        
             
        
        
        
Answer:
