Passage: Roman government was headed by two consuls, elected annually by the citizens and advised by a senate composed of appointed magistrates. As Roman society was very hierarchical by modern standards, the evolution of the Roman government was heavily influenced by the struggle between the patricians, Rome's land-holding aristocracy, who traced their ancestry to the founding of Rome, and the plebeians, the far more numerous citizen-commoners. Over time, the laws that gave patricians exclusive rights to Rome's highest offices were repealed or weakened, and leading plebeian families became full members of the aristocracy. The leaders of the Republic developed a strong tradition and morality requiring public service and patronage in peace and war, making military and political success inextricably linked. Many of Rome's legal and legislative structures (later codified into the Justinian Code, and again into the Napoleonic Code) can still be observed throughout Europe and much of the world in modern nation states and international organizations. Question: Who eventually became full members of the aristocracy?

Ex Output:
leading plebeian families

Passage: At present the A35 autoroute, which parallels the Rhine between Karlsruhe and Basel, and the A4 autoroute, which links Paris with Strasbourg, penetrate close to the centre of the city. The Grand contournement ouest (GCO) project, programmed since 1999, plans to construct a 24 km (15 mi) long highway connection between the junctions of the A4 and the A35 autoroutes in the north and of the A35 and A352 autoroutes in the south. This routes well to the west of the city and is meant to divest a significant portion of motorized traffic from the unité urbaine. Question: How far is the connection between junctions A4 and the A35?

Ex Output:
24 km

Passage: The country bounced between socialism and adherence to the neoliberal model. Land reform and nationalizations were enforced; the Portuguese Constitution (approved in 1976) was rewritten in order to accommodate socialist and communist principles. Until the constitutional revisions of 1982 and 1989, the constitution was a highly charged ideological document with numerous references to socialism, the rights of workers, and the desirability of a socialist economy. Portugal's economic situation after its transition to democracy, obliged the government to pursue International Monetary Fund (IMF)-monitored stabilization programs in 1977–78 and 1983–85. Question: For what reasons were the Portuguese Constitution rewritten?

Ex Output:

to accommodate socialist and communist principles
