premise: The Pistol model 2000 (also "md. 2000") is a semi-automatic pistol designed and manufactured by RomArm via the Cugir Arsenal of Romania. The pistol, chambered in 9×19mm Luger is an almost-identical copy of the Magnum Research Jericho 941 (Baby Eagle). The pistol is the standard sidearm of the Romanian Army.
hypothesis: The Romanian Army does not use the Pistol model 2000 very often.
reason: According to the context, this sidearm is the standard sidearm of the Romanian Army, and therefore the statement that they don't use it very often is incorrect. It was likely difficult for the system because it possibly can't truly interpret what 'standard' means in this context.
