premise: Both of these attacks, attributed to the drug trafficking cartels, took place after 10 bombs, placed in nine political offices of the Liberal and Social Conservative parties and in another bank office, exploded early this morning in downtown Bogota.
hypothesis: Downtown Bogota is a nice place to live.
reason: Downtown Bogota may or may not be a nice place to live. This bombing event could just be an isolated incident. The system likely thought that downtown Bogota was not a nice place to live because it is only focused on this negative event.
