I would say C probably. the text sort of explains how each decade is different from the previous one, but it doesn't seem to really show a strong "cause and effect."
sorry I wasn't very helpful.
Is there a picture to help me understand what ur doing
The underlying universal message of a text is the theme.
The theme is a big idea, something that you can learn about life in general.
Here are some examples of themes found in literature:
Love, such as Shakespeare's Romeo and Juliet, a tragic tale of forbidden love with terrible consequences.
Death, The Fault in Our Stars features teenage characters coming to terms with their mortality in the face of terminal illness.
Good vs. evil, The Chronicles of Narnia, C. S. Lewis', follows four siblings who pass into an entirely new world, in which they encounter characters both good (Aslan) and evil (The White Witch)
Beacause no one is being judged for what they look like and how they dres, they are all equal.
