From sonnet vii, by john milton my hasting days fly on with full career, but my late spring no bud or blossom showeth. what is the main idea of these lines from sonnet vii? the speaker is too old to continue with his writing career. the speaker is concerned that a thief has stolen his work. the speaker has not yet created a great body of work. the speaker has not taken the time to work on his garden.

The correct option is this: THE SPEAKER HAS NOT YET CREATED A GREAT BODY OF WORK.
From the excerpt given above, the speaker is saying that the time is running by hastily on a daily basis and the speaker is getting old but he believe that what he has achieved so far does not correspond to his age. The 'late spring' used in the excerpt refers to the late youthful stage. The clause 'no bud or blossom showeth' implies that no great work has been done.
