When would using a visible zipper on a costume be a problem in a play or film with a historical setting? When the zipper color does not match the costume color
When the actor does not like zippers
When the play or film takes place in a time before zippers were invented
When the costume budget is low

When the play or film takes place in a time before zippers were invented

Explanation:

If the play is in a historical settings, zippers were probably not invented. So if you had a zipper on your costume it wouldn't make sense.

Hope this helps!

tbh, either pop or, i know it's not on the list, but indie/ alternative.

lines and shapes are a part of the visual elements which can be played with and used to create a mood or feeling in a composition.

some of the other elements include the pattern, color, tone and texture. all these elements serve together as the construction blocks which are used by the artists to create artwork.

lines are used to form drawings and different shapes are formed when these lines are used in certain lengths or angles. so the artist can play with these elements of art to create and express different moods, thus conveying different  meanings.
