Problem: Religion in ancient Rome:

Chthonic gods such as Dis pater, the di inferi ("gods below"), and the collective shades of the departed (di Manes) were given dark, fertile victims in nighttime rituals. Animal sacrifice usually took the form of a holocaust or burnt offering, and there was no shared banquet, as "the living cannot share a meal with the dead". Ceres and other underworld goddesses of fruitfulness were sometimes offered pregnant female animals; Tellus was given a pregnant cow at the Fordicidia festival. Color had a general symbolic value for sacrifices. Demigods and heroes, who belonged to the heavens and the underworld, were sometimes given black-and-white victims. Robigo (or Robigus) was given red dogs and libations of red wine at the Robigalia for the protection of crops from blight and red mildew.

When were the gods below and the dead celebrated?
---
A: nighttime


Problem: Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce. The United States Code is the official compilation and codification of the general and permanent federal statutes. Many statutes give executive branch agencies the power to create regulations, which are published in the Federal Register and codified into the Code of Federal Regulations. Regulations generally also carry the force of law under the Chevron doctrine. Many lawsuits turn on the meaning of a federal statute or regulation, and judicial interpretations of such meaning carry legal force under the principle of stare decisis.
Where are regulations codified into?
---
Answer: Code of Federal Regulations


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
One of the founding members, East Germany was allowed to re-arm by the Soviet Union and the National People's Army was established as the armed forces of the country to counter the rearmament of West Germany.
Which nation was permitted rearmament by the foundation of the Warsaw Pact?
A: East Germany


Context and question: From 1938 until 1995, the U.S. Supreme Court did not invalidate any federal statute as exceeding Congress' power under the Commerce Clause. Most actions by the federal government can find some legal support among the express powers, such as the Commerce Clause, whose applicability has been narrowed by the Supreme Court in recent years. In 1995 the Supreme Court rejected the Gun-Free School Zones Act in the Lopez decision, and also rejected the civil remedy portion of the Violence Against Women Act of 1994 in the United States v. Morrison decision. Recently, the Commerce Clause was interpreted to include marijuana laws in the Gonzales v. Raich decision.
What does the commerce clause include?
Answer: include marijuana laws in the Gonzales v. Raich decision


Question: In 1886, Frank Julian Sprague invented the first practical DC motor, a non-sparking motor that maintained relatively constant speed under variable loads. Other Sprague electric inventions about this time greatly improved grid electric distribution (prior work done while employed by Thomas Edison), allowed power from electric motors to be returned to the electric grid, provided for electric distribution to trolleys via overhead wires and the trolley pole, and provided controls systems for electric operations. This allowed Sprague to use electric motors to invent the first electric trolley system in 1887–88 in Richmond VA, the electric elevator and control system in 1892, and the electric subway with independently powered centrally controlled cars, which were first installed in 1892 in Chicago by the South Side Elevated Railway where it became popularly known as the "L". Sprague's motor and related inventions led to an explosion of interest and use in electric motors for industry, while almost simultaneously another great inventor was developing its primary competitor, which would become much more widespread. The development of electric motors of acceptable efficiency was delayed for several decades by failure to recognize the extreme importance of a relatively small air gap between rotor and stator. Efficient designs have a comparatively small air gap. [a] The St. Louis motor, long used in classrooms to illustrate motor principles, is extremely inefficient for the same reason, as well as appearing nothing like a modern motor.
Is there an answer to this question: What was the transportation advancement made possible by Sprague's designs?

Answer: electric trolley system


Problem: Materialism:

The German materialist and atheist anthropologist Ludwig Feuerbach would signal a new turn in materialism through his book, The Essence of Christianity (1841), which provided a humanist account of religion as the outward projection of man's inward nature. Feuerbach's materialism would later heavily influence Karl Marx.

The author's ideas would later influence what well known philosopher?
---
A:
Karl Marx
