Question

Tú compras un boleto para ellos. (1 point) Question 5 options: 1) Los lo compras. 2) Se lo compras. 3) Se les compras.

Answer 1

Tú compras un boleto para ellos.

From the options, it appears you need to write this sentence using a direct object pronoun. The object of the sentence is un boleto, which is masculine singular. This means the direct object pronoun must be masculine singular; the direct object pronoun must be lo.

This narrows the options to 1 and 2, however the first option can be eliminated due to grammatical error (los lo, which translates to "the the", doesn't make sense).

Answer:
2) Se lo compras.
