Answer:
One way to rewrite this paragraph without figures of speech and idioms would be:
"We had the greatest vacation ever! We went to a beautiful beach. The sand was extremely white. We lay in the shade of the blowing palm trees all afternoon, watching the butterflies and birds. In the evening, the ocean was incredibly clear. We could look right down into the water and see coral reefs and bright fish. When I told my friends about it, they were all very jealous! They all said they wished they could have gone!"
Answer:
Adichie's first novel is full of symbols. The palms represent victory, the figurines personify Mama and the purple hibiscus is used as a symbol of hope and freedom in the future in connection with Jaja. The figurines and the purple hibiscus are metaphors for Mama and Jaja respectively.
I'm guessing b. because then those senses help us visualize in our head. I don't know really could be wrong but, hope it helped.
