Problem: The illuminated ceiling was once popular in the 1960s and 1970s but fell out of favor after the 1980s. This uses diffuser panels hung like a suspended ceiling below fluorescent lights, and is considered general lighting. Other forms include neon, which is not usually intended to illuminate anything else, but to actually be an artwork in itself. This would probably fall under accent lighting, though in a dark nightclub it could be considered general lighting.
When would neon lighting be considered general lighting?
The answer is the following: dark nightclub

Problem: Another recent environmental issue in Melbourne was the Victorian government project of channel deepening Melbourne Ports by dredging Port Phillip Baythe Port Phillip Channel Deepening Project. It was subject to controversy and strict regulations among fears that beaches and marine wildlife could be affected by the disturbance of heavy metals and other industrial sediments. Other major pollution problems in Melbourne include levels of bacteria including E. coli in the Yarra River and its tributaries caused by septic systems, as well as litter. Up to 350,000 cigarette butts enter the storm water runoff every day. Several programs are being implemented to minimise beach and river pollution. In February 2010, The Transition Decade, an initiative to transition human society, economics and environment towards sustainability, was launched in Melbourne.
Why was the Port Phillip Channel Deppening Project subject to controversy and strict regulations?
The answer is the following: fears that beaches and marine wildlife could be affected

Problem: The interface of Windows 8 has been the subject of mixed reaction. Bright wrote that its system of hot corners and edge swiping "wasn't very obvious" due to the lack of instructions provided by the operating system on the functions accessed through the user interface, even by the video tutorial added on the RTM release (which only instructed users to point at corners of the screen or swipe from its sides). Despite this "stumbling block", Bright said that Windows 8's interface worked well in some places, but began to feel incoherent when switching between the "Metro" and desktop environments, sometimes through inconsistent means. Tom Warren of The Verge wrote that the new interface was "as stunning as it is surprising", contributing to an "incredibly personal" experience once it is customized by the user, but had a steep learning curve, and was awkward to use with a keyboard and mouse. He noted that while forcing all users to use the new touch-oriented interface was a risky move for Microsoft as a whole, it was necessary in order to push development of apps for the Windows Store. Others, such as Adrian Kingsley-Hughes from ZDNet, considered the interface to be "clumsy and impractical" due to its inconsistent design (going as far as considering it "two operating systems unceremoniously bolted together"), and concluded that "Windows 8 wasn't born out of a need or demand; it was born out of a desire on Microsoft's part to exert its will on the PC industry and decide to shape it in a directiontouch and tablets -- that allows it to compete against, and remain relevant in the face of Apple's iPad."
Who said the Windows 8 interface was clumsy and impractical?
The answer is the following: Adrian Kingsley-Hughes
