Problem: Lighting:

Beyond the energy factors being considered, it is important not to over-design illumination, lest adverse health effects such as headache frequency, stress, and increased blood pressure be induced by the higher lighting levels. In addition, glare or excess light can decrease worker efficiency.

What can cause health effects such headache frequency?
---
A: higher lighting levels

Problem: When the board has no embedded components it is more correctly called a printed wiring board (PWB) or etched wiring board. However, the term printed wiring board has fallen into disuse. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). The IPC preferred term for assembled boards is circuit card assembly (CCA), and for assembled backplanes it is backplane assemblies. The term PCB is used informally both for bare and assembled boards.
What's the more appropriate, but mostly unused, name for a printed circuit board when it doesn't have embedded components?
---
Answer: printed wiring board

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Environmental sustainability has become a mainstream issue, with profound effect on the architectural profession. Many developers, those who support the financing of buildings, have become educated to encourage the facilitation of environmentally sustainable design, rather than solutions based primarily on immediate cost. Major examples of this can be found in Passive solar building design, greener roof designs, biodegradable materials, and more attention to a structure's energy usage. This major shift in architecture has also changed architecture schools to focus more on the environment. Sustainability in architecture was pioneered by Frank Lloyd Wright, in the 1960s by Buckminster Fuller and in the 1970s by architects such as Ian McHarg and Sim Van der Ryn in the US and Brenda and Robert Vale in the UK and New Zealand. There has been an acceleration in the number of buildings which seek to meet green building sustainable design principles. Sustainable practices that were at the core of vernacular architecture increasingly provide inspiration for environmentally and socially sustainable contemporary techniques. The U.S. Green Building Council's LEED (Leadership in Energy and Environmental Design) rating system has been instrumental in this.
Who was the last to design architecture environmentally?
A: unanswerable

Context and question: On August 1, 2012, Windows 8 (build 9200) was released to manufacturing with the build number 6.2.9200.16384 . Microsoft planned to hold a launch event on October 25, 2012 and release Windows 8 for general availability on the next day. However, only a day after its release to manufacturing, a copy of the final version of Windows 8 Enterprise N (a version for European markets lacking bundled media players to comply with a court ruling) leaked online, followed by leaks of the final versions of Windows 8 Pro and Enterprise a few days later. On August 15, 2012, Windows 8 was made available to download for MSDN and TechNet subscribers. Windows 8 was made available to Software Assurance customers on August 16, 2012. Windows 8 was made available for students with a DreamSpark Premium subscription on August 22, 2012, earlier than advertised.
What was the final build Microsoft decided to manufacture?
Answer: 9200

Question: where a single prime denotes the real part and a double prime the imaginary part, Z() is the complex impedance with the dielectric present, Ccmplx() is the so-called complex capacitance with the dielectric present, and C0 is the capacitance without the dielectric. (Measurement "without the dielectric" in principle means measurement in free space, an unattainable goal inasmuch as even the quantum vacuum is predicted to exhibit nonideal behavior, such as dichroism. For practical purposes, when measurement errors are taken into account, often a measurement in terrestrial vacuum, or simply a calculation of C0, is sufficiently accurate.)
Is there an answer to this question: How is the complex capacitance mathematically unrepresented with the dielectric present?

Answer: unanswerable

Problem: Dutch language:

The Germanic languages are traditionally divided into three groups: West, East and North Germanic. They remained mutually intelligible throughout the Migration Period. Dutch is together with English and German part of the West Germanic group, that is characterized by a number of phonological and morphological innovations not found in North and East Germanic. The West Germanic varieties of the time are generally split into three dialect groups: Ingvaeonic (North Sea Germanic), Istvaeonic (Weser-Rhine Germanic) and Irminonic (Elbe Germanic). It appears that the Frankish tribes fit primarily into the Istvaeonic dialect group with certain Ingvaeonic influences towards the northwest, still seen in modern Dutch.

In what historical period did the different types of Germanic languages stop being collectively understood?
---
A:
the Migration Period
