Question

this story is mainly about
a the types of fish in the sea.
b why the sun is hot.
c how the sunflower came to be.
d the first birds with wings.

Explanation:

To determine the main idea of the story, we analyze each option:

• Option A is about types of sea fish, which is unrelated to a story likely focused on sunflowers, sun heat, or first birds.
• Option B is about why the sun is hot, a scientific/astronomical topic, not typical of a story about origins (like sunflowers or first birds).
• Option C, "how the sunflower came to be," fits a story about the origin of a plant, which is a common narrative type (e.g., folktales or origin stories).
• Option D is about first birds with wings, a biological/evolutionary topic, less likely if the story's main focus is on sunflowers.

Among these, Option C is the most plausible for a story's main theme about an origin (sunflower's origin).

Answer:

C. how the sunflower came to be.
