A worker for a power company trims the branches of trees that overhang power lines as a prevention against damage to the lines anticipated because of the impending stormy season. βββ ββββββ βββββββ ββββ βββββ ββββ ββ ββ ββββ βββ βββ ββ ββββ βββ βββββββββββ ββββββββ ββ β βββββββ ββββ βββββββ βββ ββββββ ββ βββ ββββ ββββ βββββββββ ββββ ββββ βββββ βββ ββ ββββ βββββββ
The worker concludes that there is no need to complete a task (trim a certain tree). Her reasoning is that an outside force may eliminate the problem (the owners may cut down the tree anyway).
The workerβs reasoning has a clear flaw. The owners might decide not to cut down the tree (or cut it down after the stormy season), in which case damage could occur.
