Answer: C. Radical Republicans were less willing to allow former Confederates to participate in government.
Explanation:
Radical Republicans were so called because they advocated radical policies based on the socio-political landscape at the time in calling for an immediate, permanent and uncompensated end to slavery.
They were very opposed to former Confederates such as officers and politicians joining Congress or any other form of government so as not to give them the chance to implement confederate policies.
The answer is B: a larger urban population.
One statistic that has functioned steadily as an indicator of the level of industrialization and economic development in countries is the percentage of people living in urban areas, that is to say, people living in cities rather than on rural lands. It is a good indicator because this allows one to infer that the population of such a country is employed not in farming or fishing, but rather in industrial labor, the service industry or forms of human capital exploitation.
