Problem: Copper:

Copper's greater conductivity versus other metals enhances the electrical energy efficiency of motors. This is important because motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Increasing the mass and cross section of copper in a coil increases the electrical energy efficiency of the motor. Copper motor rotors, a new technology designed for motor applications where energy savings are prime design objectives, are enabling general-purpose induction motors to meet and exceed National Electrical Manufacturers Association (NEMA) premium efficiency standards.

What percentage of electrical consumption does motor systems use in industry?
---
A: 69%

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Copper, silver and gold are in group 11 of the periodic table, and they share certain attributes: they have one s-orbital electron on top of a filled d-electron shell and are characterized by high ductility and electrical conductivity. The filled d-shells in these elements do not contribute much to the interatomic interactions, which are dominated by the s-electrons through metallic bonds. Unlike metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. This explains the low hardness and high ductility of single crystals of copper. At the macroscopic scale, introduction of extended defects to the crystal lattice, such as grain boundaries, hinders flow of the material under applied stress, thereby increasing its hardness. For this reason, copper is usually supplied in a fine-grained polycrystalline form, which has greater strength than monocrystalline forms.
What is copper normally missing?
A: unanswerable

Context and question: In the 2004 Democratic presidential primaries, John Kerry defeated several Democratic rivals, including Sen. John Edwards (D-North Carolina.), former Vermont Governor Howard Dean and retired Army General Wesley Clark. His victory in the Iowa caucuses is widely believed to be the tipping point where Kerry revived his sagging campaign in New Hampshire and the February 3, 2004, primary states like Arizona, South Carolina and New Mexico. Kerry then went on to win landslide victories in Nevada and Wisconsin. Kerry thus won the Democratic nomination to run for President of the United States against incumbent George W. Bush. On July 6, 2004, he announced his selection of John Edwards as his running mate. Democratic strategist Bob Shrum, who was Kerry's 2004 campaign adviser, wrote an article in Time magazine claiming that after the election, Kerry had said that he wished he'd never picked Edwards, and that the two have since stopped speaking to each other. In a subsequent appearance on ABC's This Week, Kerry refused to respond to Shrum's allegation, calling it a "ridiculous waste of time."
Who won the 2004 Iowa Democratic Caucus?
Answer: John Kerry

Question: A culinary staple of North Carolina is pork barbecue. There are strong regional differences and rivalries over the sauces and methods used in making the barbecue. The common trend across Western North Carolina is the use of premium grade Boston butt. Western North Carolina pork barbecue uses a tomato-based sauce, and only the pork shoulder (dark meat) is used. Western North Carolina barbecue is commonly referred to as Lexington barbecue after the Piedmont Triad town of Lexington, home of the Lexington Barbecue Festival, which attracts over 100,000 visitors each October. Eastern North Carolina pork barbecue uses a vinegar-and-red-pepper-based sauce and the "whole hog" is cooked, thus integrating both white and dark meat.
Is there an answer to this question: What is another name for Western North Carolina Barbecue?

Answer: Lexington barbecue

Question: Logically, no number of positive outcomes at the level of experimental testing can confirm a scientific theory, but a single counterexample is logically decisive: it shows the theory, from which the implication is derived, to be false. To say that a given statement (e.g., the statement of a law of some scientific theory) -- [call it "T"] -- is "falsifiable" does not mean that "T" is false. Rather, it means that, if "T" is false, then (in principle), "T" could be shown to be false, by observation or by experiment. Popper's account of the logical asymmetry between verification and falsifiability lies at the heart of his philosophy of science. It also inspired him to take falsifiability as his criterion of demarcation between what is, and is not, genuinely scientific: a theory should be considered scientific if, and only if, it is falsifiable. This led him to attack the claims of both psychoanalysis and contemporary Marxism to scientific status, on the basis that their theories are not falsifiable.
Is there an answer to this question: What political theory did Popper say did not meet his falsifiability criterion?

Answer:
Marxism
