Problem: The original post-punk movement ended as the bands associated with the movement turned away from its aesthetics, often in favor of more commercial sounds. Many of these groups would continue recording as part of the new pop movement, with entryism becoming a popular concept. In the United States, driven by MTV and modern rock radio stations, a number of post-punk acts had an influence on or became part of the Second British Invasion of "New Music" there. Some shifted to a more commercial new wave sound (such as Gang of Four), while others were fixtures on American college radio and became early examples of alternative rock. Perhaps the most successful band to emerge from post-punk was U2, who combined elements of religious imagery together with political commentary into their often anthemic music.
Where was a lot of the post-punk pop bands played in addition to MTV?

Answer: American college radio

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On one hand, this means that the Belgian political landscape, generally speaking, consists of only two components: the Dutch-speaking population represented by Dutch-language political parties, and the majority populations of Wallonia and Brussels, represented by their French-speaking parties. The Brussels region emerges as a third component. This specific dual form of federalism, with the special position of Brussels, consequently has a number of political issueseven minor onesthat are being fought out over the Dutch/French-language political division. With such issues, a final decision is possible only in the form of a compromise. This tendency gives this dual federalism model a number of traits that generally are ascribed to confederalism, and makes the future of Belgian federalism contentious.
How many components doesn't the Belgian political landscape include?
A: unanswerable

Context and question: In December 1993, the Famicom received a similar redesign. It also loads cartridges through a covered slot on the top of the unit and uses non-hardwired controllers. Because HVC-101 used composite video output instead of being RF only like the HVC-001, Nintendo marketed the newer model as the AV Famicom (AV, Eibui Shiyo Famikon?). Since the new controllers don't have microphones on them like the second controller on the original console, certain games such as the Disk System version of The Legend of Zelda and Raid on Bungeling Bay will have certain tricks that cannot be replicated when played on an HVC-101 Famicom without a modded controller. However, the HVC-101 Famicom is compatible with most NES controllers due to having the same controller port. Nintendo had also released a 3D graphic capable headset. However, this peripheral was never released outside Japan.[citation needed]
What month and year did the Famicom receive a redesign?
Answer: December 1993

Question: Speaking in St. Petersburg, Russia on 30 June 2011, the head of Russia's United Shipbuilding Corporation said his company expected to begin design work for a new carrier in 2016, with a goal of beginning construction in 2018 and having the carrier achieve initial operational capability by 2023. Several months later, on 3 November 2011 the Russian newspaper Izvestiya reported that the naval building plan now included (first) the construction of a new shipyard capable of building large hull ships, after which Moscow will build two (80,000 tons full load each) nuclear-powered aircraft carriers by 2027. The spokesperson said one carrier would be assigned to the Russian Navy's Northern Fleet at Murmansk, and the second would be stationed with the Pacific Fleet at Vladivostok.
Is there an answer to this question: When did Russia's United Shipbuilding Corporation expect to begin design work for a new carrier?

Answer: 2016

Problem: Printed circuit board:

Multi-layer printed circuit boards have trace layers inside the board. This is achieved by laminating a stack of materials in a press by applying pressure and heat for a period of time. This results in an inseparable one piece product. For example, a four-layer PCB can be fabricated by starting from a two-sided copper-clad laminate, etch the circuitry on both sides, then laminate to the top and bottom pre-preg and copper foil. It is then drilled, plated, and etched again to get traces on top and bottom layers.

If you started with a two-sided laminate etched on either side, laminated to the top and bottom, and processed it again to get traces on the outside layers, how many layers would your final PCB have?

A:
four
