Problem: Video output connections varied from one model of the console to the next. The original HVC-001 model of the Family Computer featured only radio frequency (RF) modulator output. When the console was released in North America and Europe, support for composite video through RCA connectors was added in addition to the RF modulator. The HVC-101 model of the Famicom dropped the RF modulator entirely and adopted composite video output via a proprietary 12-pin "multi-out" connector first introduced for the Super Famicom/Super Nintendo Entertainment System. Conversely, the North American re-released NES-101 model most closely resembled the original HVC-001 model Famicom, in that it featured RF modulator output only. Finally, the PlayChoice-10 utilized an inverted RGB video output.
The Super NES had how many pins in its non-proprietary connector?

Problem: The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds. The line following the stem group Sphenacodontia split-off several diverse groups of non-mammalian synapsidssometimes referred to as mammal-like reptilesbefore giving rise to the proto-mammals (Therapsida) in the early Mesozoic era. The modern mammalian orders arose in the Paleogene and Neogene periods of the Cenozoic era, after the extinction of the non-avian dinosaurs 66 million years ago.
When did sphenacodont pelycosaurs become extinct?

Problem: Xiamen dialect, sometimes known as Amoy, is the main dialect spoken in the Chinese city of Xiamen and its surrounding regions of Tong'an and Xiang'an, both of which are now included in the Greater Xiamen area. This dialect developed in the late Ming dynasty when Xiamen was increasingly taking over Quanzhou's position as the main port of trade in southeastern China. Quanzhou traders began travelling southwards to Xiamen to carry on their businesses while Zhangzhou peasants began traveling northwards to Xiamen in search of job opportunities. It is at this time when a need for a common language arose. The Quanzhou and Zhangzhou varieties are similar in many ways (as can be seen from the common place of Henan Luoyang where they originated), but due to differences in accents, communication can be a problem. Quanzhou businessmen considered their speech to be the prestige accent and considered Zhangzhou's to be a village dialect. Over the centuries, dialect leveling occurred and the two speeches mixed to produce the Amoy dialect.
What city took over Quanzhou's position as the main port of trade in SE China?
