Answer:
Letter A is correct in this question.
Step-by-step explanation:
Perseverance is a poem written by Johann Wolfgang von Goethe, a German poet, scientist, and novelist. Since the poem has "Perseverance" as the title, it is important to remember that the word refers to the steady persistance in a purpose.
The excerpt has two lines and one (A harvest of thorns or of flowers) is the consequence of the other (Life's field will yield as we make it.) So, it means that life will give you what you share with others, making A the correct answer.
