Problem: A key component common to all CPUs is the program counter, a special memory cell (a register) that keeps track of which location in memory the next instruction is to be read from.
What is a component that all CPUs have?
The answer is the following: the program counter


Voyager 2 is the only spacecraft that has visited Neptune. The spacecraft's closest approach to the planet occurred on 25 August 1989. Because this was the last major planet the spacecraft could visit, it was decided to make a close flyby of the moon Triton, regardless of the consequences to the trajectory, similarly to what was done for Voyager 1's encounter with Saturn and its moon Titan. The images relayed back to Earth from Voyager 2 became the basis of a 1989 PBS all-night program, Neptune All Night.
What near Neptune did a spacecraft visit dangerously close?
Triton


Input: Religion in ancient Rome
Each of Rome's legendary or semi-legendary kings was associated with one or more religious institutions still known to the later Republic. Tullus Hostilius and Ancus Marcius instituted the fetial priests. The first "outsider" Etruscan king, Lucius Tarquinius Priscus, founded a Capitoline temple to the triad Jupiter, Juno and Minerva which served as the model for the highest official cult throughout the Roman world. The benevolent, divinely fathered Servius Tullius established the Latin League, its Aventine Temple to Diana, and the Compitalia to mark his social reforms. Servius Tullius was murdered and succeeded by the arrogant Tarquinius Superbus, whose expulsion marked the beginning of Rome as a republic with annually elected magistrates.

The removal of whom marked the beginning of the Roman Republic?
Output: Tarquinius Superbus


Input: Article: The assumption that black-body radiation is thermal leads to an accurate prediction: the total amount of emitted energy goes up with the temperature according to a definite rule, the Stefan–Boltzmann law (1879–84). But it was also known that the colour of the light given off by a hot object changes with the temperature, so that "white hot" is hotter than "red hot". Nevertheless, Wilhelm Wien discovered the mathematical relationship between the peaks of the curves at different temperatures, by using the principle of adiabatic invariance. At each different temperature, the curve is moved over by Wien's displacement law (1893). Wien also proposed an approximation for the spectrum of the object, which was correct at high frequencies (short wavelength) but not at low frequencies (long wavelength). It still was not clear why the spectrum of a hot object had the form that it has (see diagram).

Now answer this question: What characteristic of the light emitted by a hot object changes with temperature?

Output: the colour of the light given off


Article: One of the more prominent contestants this year was Chris Medina, whose story of caring for his brain-damaged fiancée received widespread coverage. Medina was cut in the Top 40 round. Casey Abrams, who suffers from ulcerative colitis, was hospitalized twice and missed the Top 13 result show. The judges used their one save on Abrams on the Top 11, and as a result this was the first season that 11 finalists went on tour instead of 10. In the following week, Naima Adedapo and Thia Megia were both eliminated the following week.

Question: Which contestant had a fiancé that had suffered brain damage?
Ans: Chris Medina


Input: 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?
Output:
King Evander
