Here is a question about this article: New or "virgin" heavy/heavyweight (180–220 g) vinyl is commonly used for modern audiophile vinyl releases in all genres. Many collectors prefer to have heavyweight vinyl albums, which have been reported to have better sound than normal vinyl because of their higher tolerance against deformation caused by normal play. 180 g vinyl is more expensive to produce only because it uses more vinyl. Manufacturing processes are identical regardless of weight. In fact, pressing lightweight records requires more care. An exception is the propensity of 200 g pressings to be slightly more prone to non-fill, when the vinyl biscuit does not sufficiently fill a deep groove during pressing (percussion or vocal amplitude changes are the usual locations of these artifacts). This flaw causes a grinding or scratching sound at the non-fill point.
What is the answer to this question: Which pressing of vinyl require more attention to detail, lightweight or heavyweight?
****
So... lightweight records requires more care


The problem: Answer a question about this article:
The transition from independence to a relatively minor part of a larger union was not easily accepted. To quell uprisings Charles V was struggling to exert his power over the citizens of the city, who had struggled to gain a certain level of independence from the bishops and were not willing to cede this to their new lord. The heavily fortified castle Vredenburg was built to house a large garrison whose main task was to maintain control over the city. The castle would last less than 50 years before it was demolished in an uprising in the early stages of the Dutch Revolt.
What was the purpose of the castle

The answer: The heavily fortified castle Vredenburg was built to house a large garrison whose main task was to maintain control over the city


Problem: Please answer a question about the following article about CBC Television:
On October 9, 2006 at 6:00 a.m., the network switched to a 24-hour schedule, becoming one of the last major English-language broadcasters to transition to such a schedule. Most CBC-owned stations previously signed off the air during the early morning hours (typically from 1:00 a.m. to 6:00 a.m.). Instead of the infomercials aired by most private stations, or a simulcast of CBC News Network in the style of BBC One's nightly simulcast of BBC News Channel, the CBC uses the time to air repeats, including local news, primetime series, movies and other programming from the CBC library. Its French counterpart, Ici Radio-Canada Télé, still signs off every night.
When did stations previously sign off the air?
A: early morning hours (typically from 1:00 a.m. to 6:00 a.m.)


Question: Read this and answer the question

Daniel L. Magruder, Jr defines USAF culture as a combination of the rigorous application of advanced technology, individualism and progressive airpower theory. Major General Charles J. Dunlap, Jr. adds that the U.S. Air Force's culture also includes an egalitarianism bred from officers perceiving themselves as their service's principal "warriors" working with small groups of enlisted airmen either as the service crew or the onboard crew of their aircraft. Air Force officers have never felt they needed the formal social "distance" from their enlisted force that is common in the other U.S. armed services. Although the paradigm is changing, for most of its history, the Air Force, completely unlike its sister services, has been an organization in which mostly its officers fought, not its enlisted force, the latter being primarily a rear echelon support force. When the enlisted force did go into harm's way, such as members of multi-crewed aircraft, the close comradeship of shared risk in tight quarters created traditions that shaped a somewhat different kind of officer/enlisted relationship than exists elsewhere in the military.

How have the enlisted forces of the US Air Force been seen?
Answer: primarily a rear echelon support force


Problem: Drawing from his own experiences in Scouting, Spielberg helped the Boy Scouts of America develop a merit badge in cinematography in order to help promote filmmaking as a marketable skill. The badge was launched at the 1989 National Scout Jamboree, which Spielberg attended, and where he personally counseled many boys in their work on requirements. That same year, 1989, saw the release of Indiana Jones and the Last Crusade. The opening scene shows a teenage Indiana Jones in scout uniform bearing the rank of a Life Scout. Spielberg stated he made Indiana Jones a Boy Scout in honor of his experience in Scouting. For his career accomplishments, service to others, and dedication to a new merit badge Spielberg was awarded the Distinguished Eagle Scout Award.
What was Indy's rank in Boy Scouts when shown in a movie?
The answer is the following: Life Scout


Input: Article: Due to the work nature of airline pilots, who often cross several timezones and regions of sunlight and darkness in one day, and spend many hours awake both day and night, they are often unable to maintain sleep patterns that correspond to the natural human circadian rhythm; this situation can easily lead to fatigue. The NTSB cites this as contributing to many accidents[unreliable medical source?]  and has conducted several research studies in order to find methods of combating fatigue in pilots.

Now answer this question: What has the NTSB conducted to find the cause of pilot fatigue?

Output:
research studies
