Problem: Please answer a question about the following article about Railway electrification system:
In comparison to the principal alternative, the diesel engine, electric railways offer substantially better energy efficiency, lower emissions and lower operating costs. Electric locomotives are usually quieter, more powerful, and more responsive and reliable than diesels. They have no local emissions, an important advantage in tunnels and urban areas. Some electric traction systems provide regenerative braking that turns the train's kinetic energy back into electricity and returns it to the supply system to be used by other trains or the general utility grid. While diesel locomotives burn petroleum, electricity is generated from diverse sources including many that do not produce carbon dioxide such as nuclear power and renewable forms including hydroelectric, geothermal, wind and solar.
What type of fuel do diesel locomotives use?
A: petroleum
Problem: Please answer a question about the following article about Affirmative action in the United States:
In 1976, a group of Italian American professors at City University of New York asked to be added as an affirmative action category for promotion and hiring. Italian Americans are usually considered white in the US and would not be covered under affirmative action policies, but the professors believed they were underrepresented. Libertarian economist Thomas Sowell wrote in his book, Affirmative Action Around the World: An Empirical Study, that affirmative action policies encourage non-preferred groups to designate themselves as members of preferred groups [i.e., primary beneficiaries of affirmative action] to take advantage of group preference policies.
What was the title of the book written by Thomas Sowell?
A: Affirmative Action Around the World: An Empirical Study
Problem: Please answer a question about the following article about Virgil:
Book 7 (beginning the Iliadic half) opens with an address to the muse and recounts Aeneas' arrival in Italy and betrothal to Lavinia, daughter of King Latinus. Lavinia had already been promised to Turnus, the king of the Rutulians, who is roused to war by the Fury Allecto, and Amata Lavinia's mother. In Book 8, Aeneas allies with King Evander, who occupies the future site of Rome, and is given new armor and a shield depicting Roman history. Book 9 records an assault by Nisus and Euryalus on the Rutulians, Book 10, the death of Evander's young son Pallas, and 11 the death of the Volscian warrior princess Camilla and the decision to settle the war with a duel between Aeneas and Turnus. The Aeneid ends in Book 12 with the taking of Latinus' city, the death of Amata, and Aeneas' defeat and killing of Turnus, whose pleas for mercy are spurned. The final book ends with the image of Turnus' soul lamenting as it flees to the underworld.
Which King does Aeneas ally with in Book 8 of the Aeneid?
A:
King Evander
