Romanian and English don't use the definite article in the same scenarios.
Romanian utilizes implied definite article after prepositions as the definite article is required unless explicitly stated as indefinite (”Andrei este sub o masă”).
sometimes you accept Andrei as Andrew as a correct answer and sometimes it is not accepted as a correct answer. Same as Mary =~ Maria also Ana =~ Anna.
Agreed, should be fixed to only allow the specified name as a correct answer.
