Problem: The extraordinary demands of the Punic Wars, in addition to a shortage of manpower, exposed the tactical weaknesses of the manipular legion, at least in the short term. In 217 BC, near the beginning of the Second Punic War, Rome was forced to effectively ignore its long-standing principle that its soldiers must be both citizens and property owners. During the 2nd century BC, Roman territory saw an overall decline in population, partially due to the huge losses incurred during various wars. This was accompanied by severe social stresses and the greater collapse of the middle classes. As a result, the Roman state was forced to arm its soldiers at the expense of the state, which it had not had to do in the past.
What caused the Roman state to provide armaments to their army?
The answer is the following: greater collapse of the middle classes

Yiu Yung-chin states that the furthest western extent of the Ming dynasty's territory was Gansu, Sichuan, and Yunnan while "the Ming did not possess Tibet."
What does Yiu Yung-chin claim the Ming did not possess?
The answer is the following: Tibet

Problem: The change in political structure led to the inevitable development of the peasant class or smerdy. The smerdy were free un-landed people that found work by labouring for wages on the manors which began to develop around 1031 as the verv' began to dominate socio-political structure. The smerdy were initially given equality in the Kievian law code, they were theoretically equal to the prince, so they enjoyed as much freedom as can be expected of manual labourers. However, in the 13th century they began to slowly lose their rights and became less equal in the eyes of the law.
What eventually led to the creation of the peasant/smerdy class?
The answer is the following:
change in political structure
