Question

1. para comprar un billete de tren, los pasajeros hicieron ____ en la ____. hablaron con un agente.

Explanation:

This is a Spanish language - related problem, likely about filling in the correct word for the context of buying a train ticket. The phrase "hacer cola" (to queue) is a common action when buying tickets (like at a ticket office, "ventanilla" or "taquilla" for train tickets). So the correct word to fill in the blank would be "cola" (queue) and the place could be "ventanilla" (ticket window). But from the structure, the first blank (after "hicieron") should be "cola" as "hacer cola" means to queue, and the second blank (after "en la") could be "ventanilla" (ticket window). Wait, re - reading the sentence: "Para comprar un billete de tren, los pasajeros hicieron __ en la __. Hablaron con un agente." So the first blank: "cola" (because "hacer cola" is to line up/queue), the second blank: "ventanilla" (ticket window, as that's where you queue to buy a train ticket and talk to the agent).

Answer:

First blank: cola; Second blank: ventanilla
