Tú compras un boleto para ellos. (1 point) question 5 options: 1) los lo compras. 2) se lo compras. 3) se les compras.

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).

2) Se lo compras.

The answer is dolieron.
