Hello. You did not present the poem to which this question is related. However, through the line of the poem presented in the question, it is possible to see that you are referring to the poem "Harriet Tubman" written by Eloise Greenfield. However you presented the line incorrectly, the correct one is "She ran to the woods and she ran through the woods".
Answer:
Without the use of repetition, the reader would not have realized that Harriet Tubman ran a very long way and for a long time.
Step-by-step explanation:
The poem pays homage to Harriet Tubman, an African American woman who was born a slave, but ran away and helped several slaves to escape and achieve freedom, just like her.
Harriet Tubman's escape was not an easy one, but she had to run and hide for a long time and for many paths before finding a place that would be safe and free. This difficult and long escape is reinforced in the poem by the use of repetition in the line "She ran to the woods and she ran through the woods" where the reader can see that Harriet Tubman ran a lot and for a long time.
