Problem: Lighting:

For example, in order to meet the expectations for good color rendering in retail applications, research suggests using the well-established CRI along with another metric called gamut area index (GAI). GAI represents the relative separation of object colors illuminated by a light source; the greater the GAI, the greater the apparent saturation or vividness of the object colors. As a result, light sources which balance both CRI and GAI are generally preferred over ones that have only high CRI or only high GAI.

Would a lower GAI mean higher apparent saturation or vividness of object colors?

A: ano


Problem: The service's B-2A aircraft entered service in the 1990s, its B-1B aircraft in the 1980s and its current B-52H aircraft in the early 1960s. The B-52 Stratofortress airframe design is over 60 years old and the B-52H aircraft currently in the active inventory were all built between 1960 and 1962. The B-52H is scheduled to remain in service for another 30 years, which would keep the airframe in service for nearly 90 years, an unprecedented length of service for any aircraft. The B-21 is projected to replace the B-52 and parts of the B-1B force by the mid-2020s.
When did the B-2A aircraft enter into service of the US Air Force?

Answer: 1990s

Short-term memory is believed to rely mostly on an acoustic code for storing information, and to a lesser extent a visual code. Conrad (1964) found that test subjects had more difficulty recalling collections of letters that were acoustically similar (e.g. E, P, D). Confusion with recalling acoustically similar letters rather than visually similar letters implies that the letters were encoded acoustically. Conrad's (1964) study, however, deals with the encoding of written text; thus, while memory of written language may rely on acoustic components, generalisations to all forms of memory cannot be made.
What didn't Conrad find out about test subjects?
A: unanswerable


Context and question: Trade secret misappropriation is different from violations of other intellectual property laws, since by definition trade secrets are secret, while patents and registered copyrights and trademarks are publicly available. In the United States, trade secrets are protected under state law, and states have nearly universally adopted the Uniform Trade Secrets Act. The United States also has federal law in the form of the Economic Espionage Act of 1996 (18 U.S.C. §§ 1831–1839), which makes the theft or misappropriation of a trade secret a federal crime. This law contains two provisions criminalizing two sorts of activity. The first, 18 U.S.C. § 1831(a), criminalizes the theft of trade secrets to benefit foreign powers. The second, 18 U.S.C. § 1832, criminalizes their theft for commercial or economic purposes. (The statutory penalties are different for the two offenses.) In Commonwealth common law jurisdictions, confidentiality and trade secrets are regarded as an equitable right rather than a property right but penalties for theft are roughly the same as the United States.[citation needed]
What is criminalized by the United Trade Secrets Act when for the benefit of a foreign power?
Answer: unanswerable


Question: In late 1954, Gen. J. Lawton Collins was made ambassador to "Free Vietnam" (the term South Vietnam came into use in 1955), effectively elevating the country to sovereign status. Collins' instructions were to support the leader Ngo Dinh Diem in subverting communism, by helping him to build an army and wage a military campaign. In February 1955, Eisenhower dispatched the first American soldiers to Vietnam as military advisors to Diem's army. After Diem announced the formation of the Republic of Vietnam (RVN, commonly known as South Vietnam) in October, Eisenhower immediately recognized the new state and offered military, economic, and technical assistance.
Is there an answer to this question: Who was the leader of South Vietnam in 1954?

Answer: Ngo Dinh Diem

Arsenal was the first club from the south of England to join The Football League, in 1893. They entered the First Division in 1904, and have since accumulated the second most points. Relegated only once, in 1913, they continue the longest streak in the top division. In the 1930s, Arsenal won five League Championships and two FA Cups, and another FA Cup and two Championships after the war. In 1970–71, they won their first League and FA Cup Double. Between 1988 and 2005, they won five League titles and five FA Cups, including two more Doubles. They completed the 20th century with the highest average league position.
