Problem: Copyright infringement:

In order to qualify for protection, a work must be an expression with a degree of originality, and it must be in a fixed medium, such as written down on paper or recorded digitally. The idea itself is not protected. That is, a copy of someone else's original idea is not infringing unless it copies that person's unique, tangible expression of the idea. Some of these limitations, especially regarding what qualifies as original, are embodied only in case law (judicial precedent), rather than in statutes.

What limitation is only embodied in case law, rather than statues?

A: what qualifies as original

Problem: On September 21, 1953, Thomas Watson, Jr., the company's president at the time, sent out a controversial letter to all IBM employees stating that IBM needed to hire the best people, regardless of their race, ethnic origin, or gender. He also publicized the policy so that in his negotiations to build new manufacturing plants with the governors of two states in the U.S. South, he could be clear that IBM would not build "separate-but-equal" workplaces. In 1984, IBM added sexual orientation to its nondiscrimination policy. The company stated that this would give IBM a competitive advantage because IBM would then be able to hire talented people its competitors would turn down.
What did the letter sent in 1984 state to employees?

Physically, database servers are dedicated computers that hold the actual databases and run only the DBMS and related software. Database servers are usually multiprocessor computers, with generous memory and RAID disk arrays used for stable storage. RAID is used for recovery of data if any of the disks fail. Hardware database accelerators, connected to one or more servers via a high-speed channel, are also used in large volume transaction processing environments. DBMSs are found at the heart of most database applications. DBMSs may be built around a custom multitasking kernel with built-in networking support, but modern DBMSs typically rely on a standard operating system to provide these functions. from databases before the inception of Structured Query Language (SQL). The data recovered was disparate, redundant and disorderly, since there was no proper method to fetch it and arrange it in a concrete structure.[citation needed]
How can large quantities of data be accessed?
A: Hardware database accelerators

Context and question: In the early 1970s, Universal teamed up with Paramount Pictures to form Cinema International Corporation, which distributed films by Paramount and Universal worldwide. Though Universal did produce occasional hits, among them Airport (1970), The Sting (1973), American Graffiti (also 1973), Earthquake (1974), and a big box-office success which restored the company's fortunes: Jaws (1975), Universal during the decade was primarily a television studio. When Metro-Goldwyn-Mayer purchased United Artists in 1981, MGM could not drop out of the CIC venture to merge with United Artists overseas operations. However, with future film productions from both names being released through the MGM/UA Entertainment plate, CIC decided to merge UA's international units with MGM and reformed as United International Pictures. There would be other film hits like E.T. the Extra-Terrestrial (1982), Back to the Future (1985), Field of Dreams (1989), and Jurassic Park (1993), but the film business was financially unpredictable. UIP began distributing films by start-up studio DreamWorks in 1997, due to connections the founders have with Paramount, Universal, and Amblin Entertainment. In 2001, MGM dropped out of the UIP venture, and went with 20th Century Fox's international arm to handle distribution of their titles to this day.
What company did Universal team up with in 1970?

Question: Although professional wrestling in Mexico (lucha libre) also has stories and characters, they are less emphasized. Wrestlers in Mexico are traditionally more agile and perform more aerial maneuvers than professional wrestlers in the U.S. who, more often, rely on power moves and strikes to subdue their opponents. The difference in styles is due to the independent evolution of the sport in Mexico beginning in the 1930s and the fact that wrestlers in the cruiserweight division (peso semicompleto) are often the most popular wrestlers in Mexican lucha libre. Wrestlers often execute high flying moves characteristic of lucha libre by utilizing the wrestling ring's ropes to catapult themselves towards their opponents, using intricate combinations in rapid-fire succession, and applying complex submission holds. Lucha libre is also known for its tag team wrestling matches, in which the teams are often made up of three members, instead of two as is common in the U.S.
Is there an answer to this question: What else is lucha libre known for?

Answer: tag team wrestling matches
