Problem: The elevator motor was located at the top of the shaft or beside the bottom of the shaft. Pushing the handle forward would cause the cab to rise; backwards would make it sink. The harder the pressure, the faster the elevator would move. The handle also served as a dead man switch: if the operator let go of the handle, it would return to its upright position, causing the elevator cab to stop. In time, safety interlocks would ensure that the inner and outer doors were closed before the elevator was allowed to move.
Why was the handle considered a "dead man switch"?
The answer is the following: if the operator let go of the handle, it would return to its upright position, causing the elevator cab to stop

Problem: While some commentators have called for the relocation of Tuvalu's population to Australia, New Zealand or Kioa in Fiji, in 2006 Maatia Toafa (Prime Minister from 20042006) said his government did not regard rising sea levels as such a threat that the entire population would need to be evacuated. In 2013 Enele Sopoaga, the prime minister of Tuvalu, said that relocating Tuvaluans to avoid the impact of sea level rise "should never be an option because it is self defeating in itself. For Tuvalu I think we really need to mobilise public opinion in the Pacific as well as in the [rest of] world to really talk to their lawmakers to please have some sort of moral obligation and things like that to do the right thing."
What did the Tuvalu Prime Minster say was not enough of an immediate threat to cause evacuation of the population?
The answer is the following: rising sea levels

Problem: Critics of the modern concept of the "separation of church and state" argue that it is untethered to anything in the text of the constitution and is contrary to the conception of the phrase as the Founding Fathers understood it.
