Input: Read this: By the mid-1970s, the agency had achieved a semi-automated air traffic control system using both radar and computer technology. This system required enhancement to keep pace with air traffic growth, however, especially after the Airline Deregulation Act of 1978 phased out the CAB's economic regulation of the airlines. A nationwide strike by the air traffic controllers union in 1981 forced temporary flight restrictions but failed to shut down the airspace system. During the following year, the agency unveiled a new plan for further automating its air traffic control facilities, but progress proved disappointing. In 1994, the FAA shifted to a more step-by-step approach that has provided controllers with advanced equipment.
Question: When was the nationwide strike that forced flight restrictions but failed to shutdown the aerospace system?

Output: unanswerable


QUES: According to the 2010 Census, 53.5% of Bronx's population was of Hispanic, Latino, or Spanish origin (they may be of any race); 30.1% non-Hispanic Black or African American, 10.9% of the population was non-Hispanic White, 3.4% non-Hispanic Asian, 0.6% from some other race (non-Hispanic) and 1.2% of two or more races (non-Hispanic). The U.S. Census considers the Bronx to be the most diverse area in the country. There is an 89.7 percent chance that any two residents, chosen at random, would be of different race or ethnicity.

How much of the Bronx's population is non-Hispanic White?
What is the answer?
ANS: 10.9%


QUES: Energy transfer can be considered for the special case of systems which are closed to transfers of matter. The portion of the energy which is transferred by conservative forces over a distance is measured as the work the source system does on the receiving system. The portion of the energy which does not do work during the transfer is called heat.[note 4] Energy can be transferred between systems in a variety of ways. Examples include the transmission of electromagnetic energy via photons, physical collisions which transfer kinetic energy,[note 5] and the conductive transfer of thermal energy.
What can be considered for the special case of systems which are closed to transfers of matter?

ANS: Energy transfer


Due to technical limitations, the original ReWritable CD could be written no faster than 4x speed. High Speed ReWritable CD has a different design, which permits writing at speeds ranging from 4x to 12x. Original CD-RW drives can only write to original ReWritable CDs. High Speed CD-RW drives can typically write to both original ReWritable CDs and High Speed ReWritable CDs. Both types of CD-RW discs can be read in most CD drives. Higher speed CD-RW discs, Ultra Speed (16x to 24x write speed) and Ultra Speed+ (32x write speed) are now available.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Does a High Speed CD-RW drive write faster on ReWriteable CDs or High Speed ReWritable CDs?
Ah, so.. unanswerable


Question: All vertebrates have a blood–brain barrier that allows metabolism inside the brain to operate differently from metabolism in other parts of the body. Glial cells play a major role in brain metabolism by controlling the chemical composition of the fluid that surrounds neurons, including levels of ions and nutrients.
Try to answer this question if possible: What type of cells have a huge role in brain metabolism?
Answer: Glial cells


Context and question: A national university is generally a university created or run by a national state but at the same time represents a state autonomic institution which functions as a completely independent body inside of the same state. Some national universities are closely associated with national cultural or political aspirations, for instance the National University of Ireland in the early days of Irish independence collected a large amount of information on the Irish language and Irish culture. Reforms in Argentina were the result of the University Revolution of 1918 and its posterior reforms by incorporating values that sought for a more equal and laic higher education system.
In what year did Argentina's University Revolution occur?
Answer:
1918
