[EX Q]: Passage: Cultural and career issues in the U.S. Air Force have been cited as one of the reasons for the shortfall in needed UAV operators. In spite of an urgent need for UAVs or drones to provide round the clock coverage for American troops during the Iraq War, the USAF did not establish a new career field for piloting them until the last year of that war and in 2014 changed its RPA training syllabus again, in the face of large aircraft losses in training, and in response to a GAO report critical of handling of drone programs. Paul Scharre has reported that the cultural divide between the USAF and US Army has kept both services from adopting each other's drone handing innovations. Question: What is the reason for the shortage of UAV operators in the US Air Force?
[EX A]: Cultural and career issues

[EX Q]: Passage: Within Galicia are the Autopista AP-9 from Ferrol to Vigo and the Autopista AP-53 (also known as AG-53, because it was initially built by the Xunta de Galicia) from Santiago to Ourense. Additional roads under construction include Autovia A-54 from Santiago de Compostela to Lugo, and Autovia A-56 from Lugo to Ourense. The Xunta de Galicia has built roads connecting comarcal capitals, such as the aforementioned AG-53, Autovia AG-55 connecting A Coruna to Carballo or AG-41 connecting Pontevedra to Sanxenxo. Question: The Autopista AP-53 was originally built by whom?
[EX A]: Xunta de Galicia

[EX Q]: Passage: The clearance of the pathogens, either treatment-induced or spontaneous, it can be influenced by the genetic variants carried by the individual patients. For instance, for genotype 1 hepatitis C treated with Pegylated interferon-alpha-2a or Pegylated interferon-alpha-2b (brand names Pegasys or PEG-Intron) combined with ribavirin, it has been shown that genetic polymorphisms near the human IL28B gene, encoding interferon lambda 3, are associated with significant differences in the treatment-induced clearance of the virus. This finding, originally reported in Nature, showed that genotype 1 hepatitis C patients carrying certain genetic variant alleles near the IL28B gene are more possibly to achieve sustained virological response after the treatment than others. Later report from Nature demonstrated that the same genetic variants are also associated with the natural clearance of the genotype 1 hepatitis C virus. Question: What is the brand name Pegasys for?
[EX A]:
Pegylated interferon-alpha-2b
