Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

[Q]: Context: Miles Monroe (Woody Allen), a jazz musician and owner of the "Happy Carrot" health-food store in 1973, is subjected to cryopreservation without his consent, and not revived for 200 years.[2] The scientists who revive him are members of a rebellion: 22nd-century America seems to be a police state, ruled by a dictator about to implement a secret plan known as the "Aries Project". The rebels hope to use Miles as a spy to infiltrate the Aries Project, because he is the only member of this society without a known biometric identity. The authorities discover the scientists' project, and arrest them. Miles escapes by disguising himself as a robot, and goes to work as a butler in the house of socialite Luna Schlosser (Diane Keaton). When Luna decides to have his head replaced with something more "aesthetically pleasing," Miles reveals his true identity to her, whereupon Luna threatens to give Miles to the authorities. In response, he kidnaps her and goes on the run, searching for the Aries Project. Miles and Luna fall in love, but Miles is captured and brainwashed into becoming a complacent member of the society, while Luna joins the rebellion. The rebels kidnap Miles and perform reverse-brainwashing, whereupon he remembers his past and joins their efforts. Miles becomes jealous when he catches Luna kissing the rebel leader, Erno Windt (John Beck), and she tells him that she believes in free love. Miles and Luna infiltrate the Aries Project, wherein they quickly learn that the national leader had been killed by a rebel bomb ten months previously. All that survives is his nose. Other members of the Aries Project, mistaking Miles and Luna for doctors, expect them to clone the leader from this single remaining part. Miles steals the nose and "assassinates" it by dropping it in the path of a road roller. After escaping, Miles and Luna debate their future together. He tells her that Erno will inevitably become as corrupt as the Leader. Miles and Luna confess their love for one another, but she claims that science has proven men and women cannot have meaningful relationships due to chemical incompatibilities. Miles dismisses this, saying that he does not believe in science, and Luna points out that he does not believe in God or political systems either. Luna asks Miles if there is anything he does believe in, and he responds with the line, "Sex and deathtwo things that come once in a lifetimebut at least after death you're not nauseous."[3] The film ends as the two embrace. 
 Question: Who catches onto the scientists' project?
[A]: the police or the authorities


[Q]: Context: An electric transformer is a device that uses electromagnetic induction to change the voltage of electric current. Electromagnetic induction is the process of generating current with a magnetic field. It occurs when a magnetic field and electric conductor, such as a coil of wire, move relative to one another. A transformer may either increase or decrease voltage. You can see the basic components of an electric transformer in the Figure 1.1. Click image to the left or use the URL below. URL: The transformer in the diagram consists of two wire coils wrapped around an iron core. Each coil is part of a different circuit. When alternating current passes through coil P, it magnetizes the iron core. Because the current is alternating, the magnetic field of the iron core keeps reversing. This is where electromagnetic induction comes in. The changing magnetic field induces alternating current in coil S of the other circuit. Notice that coil P and coil S in the Figure 1.1 have the same number of turns of wire. In this case, the voltages of the primary and secondary currents are the same. Usually, the two coils of a transformer have different numbers of turns. In that case, the voltages of the two currents are different. When coil S has more turns than coil P, the voltage in the secondary current is greater than the voltage in the primary current (see Figure 1.2). This type of transformer is called a step-up transformer. Thats because it steps up, or increases, the voltage. When coil S has fewer turns of wire than coil P, the voltage in the secondary current is less than the voltage in the primary current (see Figure 1.3). This type of transformer is called a step-down transformer because it steps down, or decreases, the voltage. Q: Both step-up and step-down transformers are used in the electrical grid that carries electricity from a power plant to your home. Where in the grid do you think step-down transformers might be used? A: One place that step-down transformers are used is on the electric poles that supply current to homes. They reduce the voltage of the electric current before it enters home circuits. 
 Question: an electric transformer contains
[A]: an iron core.


[Q]: Context: Trying to snap a three-game losing streak, the 49ers flew to Giants Stadium for a Week 7 brawl with the New York Giants. With QB Alex Smith still recovering from a shoulder injury, back-up Trent Dilfer once again got the start. In the first quarter, the Niners trailed early as Giants QB Eli Manning hooked up with WR Amani Toomer on a 4-yard TD pass (with a missed PAT) for the only score of the period. In the second quarter, San Francisco took the lead with Dilfer completing a 17-yard TD pass to WR Arnaz Battle. However, New York responded with RB Brandon Jacobs getting a 5-yard TD run, while kicker Lawrence Tynes nailed field goals of 29 and 39 yards. In the third quarter, things got worse for the Niners as Giants DE Osi Umenyiora sacked Dilfer, causing a fumble, picked up the loose ball, and ran 75 yards for a touchdown. San Francisco would manage to get a safety as FB Moran Norris blocked a punt, which went out of bounds in the endzone. In the fourth quarter, New York sealed its win with Manning completing a 2-yard TD pass to TE Jeremy Shockey. The Niners ended its day with Dilfer completing a 1-yard TD pass to WR Darrell Jackson (with a failed 2-point conversion). 
 Question: Which receiver had the longest touchdown reception of the game?
[A]:
arnaz battle
