Many of these sentences with 'personnel' seem to be based on the idea that it's a singular word representing a singular individual, which is not the case in English. It always represents a plural group in common English usage, being defined as: "people employed in an organization or engaged in an organized undertaking such as military service."

Din cate stiu, "your" inseamna si "al tau" si "al vostru", prin urmare din ce cauza e acceptata doar una din cele doua propozitii?
