Who withdrew from the torch event?
---
A: Lin Hatfield Dodds


Problem: Printed circuit board:

In boundary scan testing, test circuits integrated into various ICs on the board form temporary connections between the PCB traces to test that the ICs are mounted correctly. Boundary scan testing requires that all the ICs to be tested use a standard test configuration procedure, the most common one being the Joint Test Action Group (JTAG) standard. The JTAG test architecture provides a means to test interconnects between integrated circuits on a board without using physical test probes. JTAG tool vendors provide various types of stimulus and sophisticated algorithms, not only to detect the failing nets, but also to isolate the faults to specific nets, devices, and pins.

To whom would you go to acquire the algorithms you'd use for the Joint Test Action Group procedures?
---
A: JTAG tool vendors


Problem: Light-emitting diode:

While LEDs have the advantage over fluorescent lamps that they do not contain mercury, they may contain other hazardous metals such as lead and arsenic. Regarding the toxicity of LEDs when treated as waste, a study published in 2011 stated: "According to federal standards, LEDs are not hazardous except for low-intensity red LEDs, which leached Pb [lead] at levels exceeding regulatory limits (186 mg/L; regulatory limit: 5). However, according to California regulations, excessive levels of copper (up to 3892 mg/kg; limit: 2500), lead (up to 8103 mg/kg; limit: 1000), nickel (up to 4797 mg/kg; limit: 2000), or silver (up to 721 mg/kg; limit: 500) render all except low-intensity yellow LEDs hazardous."

What LEDs are considered safer than any other?
---
A: low-intensity yellow LEDs


Problem: Westminster Abbey:

The Westminster Abbey Museum is located in the 11th-century vaulted undercroft beneath the former monks' dormitory in Westminster Abbey. This is one of the oldest areas of the abbey, dating back almost to the foundation of the church by Edward the Confessor in 1065. This space has been used as a museum since 1908.

The vaulted undercroft beneath the monks' dormitory hasn't been a museum since when?
