Answer:
Musicals include every person's voice and their voices are incorporated in to one song that is trying to tell some form of a story. It wouldn't be a musical if there were one person right? So the "collaborative" part induces the fact that it is a musical with multiple roles for singing and acting. I hope this will help you, this answer came truly from me. Thank you.
If you're using paper, find the object you want to use for the texture. Put the paper on top of the texture. Whatever media you're using (pencil, charcoal, paint, oil pastels, etc.) lightly brush over the paper with your pencil for example, while your texture is underneath.
Informational would probably be my guess. Is there answer choices?
