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: There are less than sixty bombs used by them
reason: There were only ten bombs making this statement correct. The model caught my statement the first three times, but adding the phrase used by them was enough to fool it. The model might have problems dealing with longer statements.
