<u>Right Answer:
</u>
<u>
</u>
<h2>entradas…la taquilla
</h2><h2>
</h2>
According to the context this is the right option. When you go to the movie theater you have to buy tickets (entradas) at the ticket office (taquilla) if you want to watch the movie.
Then, the complete sentence is:
<h2>Tenemos que comprar <u>entradas</u> en <u>la taquilla </u>para entrar en el cine. </h2>
We have to buy <u>tickets </u>at the <u>ticket office</u> to enter the movie theater
The options <em>escenas</em> (scenes), <em>el teatro</em> (the theater), <em>filas</em> (lines), <em>la butaca </em>(the seat), <em>pantallas</em> (screens) and <em>el cine</em> (the cinema or movie theater) do not match the context of the sentence
.
