Answer: Chronosystem.
Urie Bronfenbrenner, an American psychologist, developed the Ecological Systems Theory as an explanation to how children interact with their environment and how in turn the environment affects the child’s development.
The first four levels of the system are:
Microsystem <em>(Immediate Environment)
</em>
Mesosystem <em>(Connections)
</em>
Exosystem <em>(Indirect Environment)
</em>
Macrosystem <em>(Social and Cultural Values)
</em>
The last system, which underlies all the other levels is the Chronosystem. This system introduces time to the theory. It includes changes over time in a small level (changes to family structure, changes in social circle) and changes at a social level (wars, recessions, etc.).

It is not B because the passage does not state anything about people preferring to ride in wagons to riding by train
So it is A because truly it was a difficult process
The correct sentence of the four is this one:
<span>Neither the train nor the bus runs that late.
and in this sentence the verb agrees with the compound subject, in the rest it does not (but it would not be a big mistake if the verb was in plural form here- there are arguments for a plural form here too).</span>
