Question

Which statement best explains why the Roman Republic ended in civil wars?
Nothing had been done to ease the tensions between the patricians and poor plebeians.
Tiberius Gracchus had a bitter personal feud with the leading senator, Publius Nasica.
A lack of land-holding citizens caused generals to recruit landless poor people, whose loyalty was to the generals that paid and rewarded them.
The poorer citizens were upset at the obvious unfairness of voting in the assembly of the centuries.

Answer 1

The best option from the list would be that "A lack of land-holding citizens caused generals to recruit landless poor people, whose loyalty was to the generals that paid and rewarded them," although a much better reason would be because Rome had conquered so much territory that the power structure was spread too thin.
