Problem: Electric motor:

A commutator is a mechanism used to switch the input of most DC machines and certain AC machines consisting of slip ring segments insulated from each other and from the electric motor's shaft. The motor's armature current is supplied through the stationary brushes in contact with the revolving commutator, which causes required current reversal and applies power to the machine in an optimal manner as the rotor rotates from pole to pole. In absence of such current reversal, the motor would brake to a stop. In light of significant advances in the past few decades due to improved technologies in electronic controller, sensorless control, induction motor, and permanent magnet motor fields, electromechanically commutated motors are increasingly being displaced by externally commutated induction and permanent-magnet motors.

What two motor types are ascendant today?
---
A: externally commutated induction and permanent-magnet

Problem: Israel:

In July 2006, a Hezbollah artillery assault on Israel's northern border communities and a cross-border abduction of two Israeli soldiers precipitated the month-long Second Lebanon War. On 6 September 2007, the Israeli Air Force destroyed a nuclear reactor in Syria. In May 2008, Israel confirmed it had been discussing a peace treaty with Syria for a year, with Turkey as a go-between. However, at the end of the year, Israel entered another conflict as a ceasefire between Hamas and Israel collapsed. The Gaza War lasted three weeks and ended after Israel announced a unilateral ceasefire. Hamas announced its own ceasefire, with its own conditions of complete withdrawal and opening of border crossings. Despite neither the rocket launchings nor Israeli retaliatory strikes having completely stopped, the fragile ceasefire remained in order. In what Israel described as a response to more than a hundred Palestinian rocket attacks on southern Israeli cities, Israel began an operation in Gaza on 14 November 2012, lasting eight days. Israel started another operation in Gaza following an escalation of rocket attacks by Hamas in July 2014.

When did the Israeli Air Force destroy a nuclear reactor in Syria?
---
A: 6 September 2007

Problem: Kathmandu:

The fire service, known as the Barun Yantra Karyalaya, opened its first station in Kathmandu in 1937 with a single vehicle. An iron tower was erected to monitor the city and watch for fire. As a precautionary measure, firemen were sent to the areas which were designated as accident-prone areas. In 1944, the fire service was extended to the neighboring cities of Lalitpur and Bhaktapur. In 1966, a fire service was established in Kathmandu airport. In 1975, a West German government donation added seven fire engines to Kathmandu's fire service. The fire service in the city is also overlooked by an international non-governmental organization, the Firefighters Volunteer Association of Nepal (FAN), which was established in 2000 with the purpose of raising public awareness about fire and improving safety.

When did Bhaktapur receive coverage from the fire department?
---
A: 1944

Problem: Nintendo Entertainment System:

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?

A:
unanswerable
