Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: Three neighborhood teens and childhood friends, Alex, Tuck, and Munch, are upset by the fact that their neighborhood, Mulberry Woods, Nevada, is going to be demolished, allegedly for a new highway construction project, and they all have to move away because of it.
While at Tuck's house, their phones start to glitch out, displaying seemingly random graphical patterns. They soon find out, through Munch, that the patterns are actually a map to a spot in the desert 17.6 miles away. They decide to go to the desert on their bikes and disguise it as a sleepover, recording the experience on various cameras because it's their last night together.
Tuck, Alex, and Munch eventually make it to the desert, and they follow the map to a dusty, rusted object under an electrical tower. Tuck, confused, decides to abruptly call it off when the object starts to copy Alex's ringtone, and they follow another map to a barn. There the object telekinetically starts to repair itself, and the boys find it contains an alien that can answer questions with "Yes" or "No" answers, from which they learn it is from outer space, has crash landed after being shot down by an unknown force, and is seriously injured.
They follow another map to a pawn shop, where the object further repairs itself, allowing the alien to reveal itself, using Alex's phone camera to "see" and befriend the three. While in an alley, they decide to name the alien "Echo." Looking for more parts to repair Echo, they again follow another map to a house where Emma, a girl who goes to their high school, lives and finds out about Echo. Emma soon joins the team, as they go to a bar, then an arcade, and she finds out the object Echo is in is a key to a spaceship hidden in Mulberry Woods.
A:
Who names the alien?
