Respuesta :
The answer is at midlife. The first clue is "half of my days". It expresses the poet's blindness at a time he feels he has more life to live. It creates the scenario of losing his talent to write. Since it was "half of his days" it also could not indicate the poet's youth. The poem also does not mention spring.
Answer: D) At midlife.
Explanation: In the given passage from "Sonnet XIX" by John Milton, the speaker is in his late life, he thinks his life is ending and he is remembering how he has spend half of his life without being able to see ("...in this dark world and wide"), we know that he lost his vision at midlife because he expresses it with the phrase "Ere half my days" and then he lost his talent.
