Final answer:
The sentence, 'Who is el mapa?', translates to 'Whose is the map?'. Considering 'el' as the pronoun, the sentence would be written as, 'El mapa es de él' or 'Es de él', meaning 'The map is his' or 'It is his'. Correct usage of object personal pronouns is important in conveying accurate meanings.
Step-by-step explanation:
The question asked requires us to use the preposition 'de' which means 'of', and a pronoun which is 'el' in this context. In Spanish, we show possession using 'de'. The given sentence is, 'Who is el mapa?', which in terms of possession means, 'Whose is the map?' Given the pronoun 'el' in the parentheses, your sentence will become 'El mapa es de él' or 'Es de él', which translates to, 'The map is his' or 'It is his'.
The usage of the right object personal pronoun 'el' is important here, transforming the meaning completely. This highlights the necessity to correctly differentiate between subject personal pronouns and object personal pronouns.
