Teacher: Now, understand the problem? Solve this instance: Passage: I selected the space on the wall I wanted for my poster . I did not want to put holes in the wall with nails , so I used double-sided tape instead of nails . I unrolled the poster flat and put it on the surface of my kitchen table . Meanwhile , I inspected the wall and made sure it was clean . Once the poster was sufficiently flattened , I took my books off of it and carried it into the room for hanging . I attached pieces of double-sided tape to the back of the poster to attach to the wall . \ nI placed the taped side of the poster against the wall , pressing down firmly on the center and corners of the poster . Once it adhered to the wall , I stepped back to amke sure it looked straight , which it did . Question: What did they help take the curl out of? Option1: Tape. Option2: A poster.
Student:
A poster.
