a) Nkrumah's government held too much power, and officials could do whatever they wanted.

Opposition parties have an important role to play in democracies. The role of these parties is to control the party in power. The threat of being able to lose their power makes the party in power more likely to fulfill the citizens' demands. In the case of Ghana, opposition parties were banned. This means that the governing party had no risk of losing their power. This confidence and excess of power reduces accountability, and in the case of Ghana, severely increased corruption.
