Ex Input:
Question: I'm trying to describe a situation in which a person prepares for an event, then realises the event won't happen, and so they undo their preparations, returning to a state of unpreparedness. Whenever I search for the opposite of "prepare", I get words that describe a failure to prepare in the first place, or at best words that describe what happens to the preparations, not words that describe what happens to the person. Is there a word that captures what happens to the person as they return to a state of unpreparedness? 
Answer: There is the phrase "stand down" about which Lexico says stand down PHRASAL VERB 2 Relax or cause to relax after a state of readiness. If something doesn't happen soon, I reckon they'll stand us down. An ambulance crew was dispatched immediately, however they were stood down shortly after. They have got to accept that the war is over and stand down their army once and for all.

Ex Output:
yes

Ex Input:
Question: What is the history of the word "troubleshoot"? At face value, it seems to be mean "aiming for trouble." Which must be short-hand for locating the source of the trouble by reproducing it under different circumstances. How did the term come to be? Who were the first "troubleshooters"? 
Answer: Why would anyone not see an original link to guns in the term? The logic would flow from issues in the old American West which was, for the most part, lawless. In those days, if a rancher or farmer had trouble with wild animals attacking his livelihood, his first recourse would be to shoot the offending animal. If claim jumpers were bothering (troubling) miners, they got shot. If some patron caused trouble in a bar, he got shot. Even the Indians of the day were prone to pull down telegraph wires that the White Man put up across their territory. Doing so made them troublemakers that required troubleshooters to balance the scales. This begs the answer that the term evolved to describe telegraph repair that would require firepower to back it up.
