Instead of the troika coming, there was a power struggle and Stalin took control of the country. He managed to remove all his political opponents and collectivize the properties which led to a rapid industrialization. There was no troika because Stalin ruled himself with an iron fist. He stayed in that position until he died in 1953.
The correct answer is Inclusion
Inclusion is the set of means and actions that combat exclusion from the benefits of living in society, caused by differences in social class, education, age, disability, gender, social prejudice or racial prejudice. Social inclusion means offering equal opportunities for everyone to access goods and services.
