What are the underlined words?
The correct answer is "mirar vidrieras".
"Mirar vidrieras" means to window-shop and it is the best option because the speaker of the sentence is <u>referring to a situation in which he/she does not have any money to spend. Window-shopping is the activity to look at items on sale without intending to buy any of them, that is, without spending any money</u>. On the other hand, the other options imply activities that demand giving your money to someone.
That’s one rule you can search up the passage and look for context clue in it.
