Why do you think the author chose to use the words prime time in the title?
a to reveal her knowledge about prime numbers and cicada instincts
b to focus on the importance of the insect's well-timed life cycle
c to highlight how researchers solved a puzzling mystery about the insect
d to emphasize that cicadas must emerge in the evening in order to survive

B to focus on the importance of the insect's well-timed life cycle

Explanation:

Some of the cicadas can only be seen at an interval of 17 years, while others  every 13 years. This shows that the life cycle of these insect's revolve around prime numbers, since both 17 and 13 are prime numbers. Thus, the writer tried to synergise the life cycle of the insects with the prime numbered years.

the correct answer is "the rhythm and rhyme scheme add to an eerie and suspenseful tone". poetry is literature written in stanzas and lines that use rhythm to express feelings and ideas. poets will pay particular attention to the length, placement, and grouping of lines and stanzas. this is called form. lines or whole stanzas can be rearranged in order to create a specific effect on the reader.
