Problem: Law of the United States:

The fifty American states are separate sovereigns, with their own state constitutions, state governments, and state courts. All states have a legislative branch which enacts state statutes, an executive branch that promulgates state regulations pursuant to statutory authorization, and a judicial branch that applies, interprets, and occasionally overturns both state statutes and regulations, as well as local ordinances. They retain plenary power to make laws covering anything not preempted by the federal Constitution, federal statutes, or international treaties ratified by the federal Senate. Normally, state supreme courts are the final interpreters of state constitutions and state law, unless their interpretation itself presents a federal issue, in which case a decision may be appealed to the U.S. Supreme Court by way of a petition for writ of certiorari. State laws have dramatically diverged in the centuries since independence, to the extent that the United States cannot be regarded as one legal system as to the majority of types of law traditionally under state control, but must be regarded as 50 separate systems of tort law, family law, property law, contract law, criminal law, and so on.

Which branch of government promulgates state regulations?

A: executive branch


Problem: IPod:

In September 2007, during a lawsuit with patent holding company Burst.com, Apple drew attention to a patent for a similar device that was developed in 1979. Kane Kramer applied for a UK patent for his design of a "plastic music box" in 1981, which he called the IXI. He was unable to secure funding to renew the US$120,000 worldwide patent, so it lapsed and Kramer never profited from his idea.

Who previously applied for a patent for an iPod-like device?
---
A: Kane Kramer


Problem: Queen (band):

While attending Ealing Art College, Tim Staffell became friends with Farrokh Bulsara, a fellow student who had assumed the English name of Freddie. Bulsara felt that he and the band had the same tastes and soon became a keen fan of Smile. In late 1970, after Staffell left to join the band Humpy Bong, the remaining Smile members, encouraged by Bulsara, changed their name to "Queen" and continued working together. When asked about the name, Bulsara explained, "I thought up the name Queen. It's just a name, but it's very regal obviously, and it sounds splendid. It's a strong name, very universal and immediate. It had a lot of visual potential and was open to all sorts of interpretations. I was certainly aware of gay connotations, but that was just one facet of it."

What band did Tim Staffell join after leaving Smile?
---
A: Humpy Bong
