Ex Input:
Passage: By the spring of 49 BC, the hardened legions of Caesar crossed the river Rubicon, the legal boundary of Roman Italy beyond which no commander might bring his army, and swept down the Italian peninsula towards Rome, while Pompey ordered the abandonment of Rome. Afterwards Caesar turned his attention to the Pompeian stronghold of Hispania (modern Spain) but decided to tackle Pompey himself in Greece. Pompey initially defeated Caesar, but failed to follow up on the victory, and was decisively defeated at the Battle of Pharsalus in 48 BC, despite outnumbering Caesar's forces two to one, albeit with inferior quality troops. Pompey fled again, this time to Egypt, where he was murdered. Question: Who decided to attack Pompey in Greece?

Ex Output:
Caesar

Passage: Caesar became consul in 59 BC. His colleague, Marcus Calpurnius Bibulus, was an extreme aristocrat. Caesar submitted the laws that he had promised Pompey to the assemblies. Bibulus attempted to obstruct the enactment of these laws, and so Caesar used violent means to ensure their passage. Caesar was then made governor of three provinces. He facilitated the election of the former patrician Publius Clodius Pulcher to the tribunate for 58 BC. Clodius set about depriving Caesar's senatorial enemies of two of their more obstinate leaders in Cato and Cicero. Clodius was a bitter opponent of Cicero because Cicero had testified against him in a sacrilege case. Clodius attempted to try Cicero for executing citizens without a trial during the Catiline conspiracy, resulting in Cicero going into self-imposed exile and his house in Rome being burnt down. Clodius also passed a bill that forced Cato to lead the invasion of Cyprus which would keep him away from Rome for some years. Clodius also passed a law to expand the previous partial grain subsidy to a fully free grain dole for citizens. Question: Who enacted a law that would increase the partial grain subsidy?

Ex Output:
Clodius

Passage: Filming temporarily returned to England to shoot scenes at Blenheim Palace in Oxfordshire, which stood in for a location in Rome, before moving on to the city itself for a five-week shoot across the city, with locations including the Ponte Sisto bridge and the Roman Forum. The production faced opposition from a variety of special interest groups and city authorities, who were concerned about the potential for damage to historical sites around the city, and problems with graffiti and rubbish appearing in the film. A car chase scene set along the banks of the Tiber River and through the streets of Rome featured an Aston Martin DB10 and a Jaguar C-X75. The C-X75 was originally developed as a hybrid electric vehicle with four independent electric engines powered by two jet turbines, before the project was cancelled. The version used for filming was converted to use a conventional internal combustion engine, to minimise the potential for disruption from mechanical problems with the complex hybrid system. The C-X75s used for filming were developed by the engineering division of Formula One racing team Williams, who built the original C-X75 prototype for Jaguar. Question: For which auto maker did Williams first develop the C-X75?

Ex Output:

Jaguar
