A different format, CD-4 (not to be confused with compact disc), by RCA, encoded the front-rear difference information on an ultrasonic carrier, which required a special wideband cartridge to capture it on carefully calibrated pickup arm/turntable combinations. CD-4 was even less successful than the two matrixed formats. (A further problem was that no cutting heads were available that could handle the HF information. That was remedied by cutting at half the speed. Later, the special half-speed cutting heads and equalization techniques were employed to get a wider frequency response in stereo with reduced distortion and greater headroom.)

What was a major issue with CD-4 technology?
Answer: no cutting heads were available that could handle the HF information

Problem: In a nonpartisan system, no official political parties exist, sometimes reflecting legal restrictions on political parties. In nonpartisan elections, each candidate is eligible for office on his or her own merits. In nonpartisan legislatures, there are no typically formal party alignments within the legislature. The administration of George Washington and the first few sessions of the United States Congress were nonpartisan. Washington also warned against political parties during his Farewell Address. In the United States, the unicameral legislature of Nebraska is nonpartisan but is elected and votes on informal party lines. In Canada, the territorial legislatures of the Northwest Territories and Nunavut are nonpartisan. In New Zealand, Tokelau has a nonpartisan parliament. Many city and county governments[vague] are nonpartisan. Nonpartisan elections and modes of governance are common outside of state institutions. Unless there are legal prohibitions against political parties, factions within nonpartisan systems often evolve into political parties.
Was the administration of George Washington nonpartisan?
The answer is the following: The administration of George Washington and the first few sessions of the United States Congress were nonpartisan.

In a major split in the ranks of Al Qaeda's organization, the Iraqi franchise, known as Al Qaeda in Iraq covertly invaded Syria and the Levant and began participating in the ongoing Syrian Civil War, gaining enough support and strength to re-invade Iraq's western provinces under the name of the Islamic State of Iraq and the Levant (ISIS/ISIL), taking over much of the country in a blitzkrieg-like action and combining the Iraq insurgency and Syrian Civil War into a single conflict. Due to their extreme brutality and a complete change in their overall ideology, Al Qaeda's core organization in Central Asia eventually denounced ISIS and directed their affiliates to cut off all ties with this organization. Many analysts[who?] believe that because of this schism, Al Qaeda and ISIL are now in a competition to retain the title of the world's most powerful terrorist organization.
Who denounced ISIS?
Al Qaeda's core organization

Input: Plymouth
The city's airport was Plymouth City Airport about 4 miles (6 km) north of the city centre. The airport was home to the local airline Air Southwest, which operated flights across the United Kingdom and Ireland. In June 2003, a report by the South West RDA was published looking at the future of aviation in the south-west and the possible closure of airports. It concluded that the best option for the south-west was to close Plymouth City Airport and expand Exeter International Airport and Newquay Cornwall Airport, although it did conclude that this was not the best option for Plymouth. In April 2011, it was announced that the airport would close, which it did on 23 December. However, FlyPlymouth plans to reopen the city airport by 2018, which will provide daily services to various destinations including London.

In kilometers, how far away from the Plymouth city center was Plymouth City Airport?
Output: 6

Input: Article: Roughly one quarter of all zinc output in the United States (2009), is consumed in the form of zinc compounds; a variety of which are used industrially. Zinc oxide is widely used as a white pigment in paints, and as a catalyst in the manufacture of rubber. It is also used as a heat disperser for the rubber and acts to protect its polymers from ultraviolet radiation (the same UV protection is conferred to plastics containing zinc oxide). The semiconductor properties of zinc oxide make it useful in varistors and photocopying products. The zinc zinc-oxide cycle is a two step thermochemical process based on zinc and zinc oxide for hydrogen production.

Now answer this question: What protects the polymers in rubber from ultraviolet radiation?

Output: Zinc oxide

Problem: On 20 May 2011, Royal Dutch Shell's final investment decision for the world's first floating liquefied natural gas (FLNG) facility was finalized following the discovery of the remote offshore Prelude fieldlocated off Australia's northwestern coast and estimated to contain about 3 trillion cubic feet of natural gas equivalent reservesin 2007. FLNG technology is based on liquefied natural gas (LNG) developments that were pioneered in the mid-20th century and facilitates the exploitation of untapped natural gas reserves located in remote areas, often too small to extract any other way.
The final investment decision for what was finalized by Royal Dutch Shell in May 2011?
The answer is the following:
the world's first floating liquefied natural gas (FLNG) facility
