What archetype does the speaker of this poem BEST represent?
the tyrant
B)
the champion
the best friend
D)
the lovesick man

Based on what I found this poem is in the category of Pastorals, which Renaissance poets like Marlowe wrote to convey their thoughts and feelings about love and other subjects. Pastorals contain idealized, rural settings. In "The Passionate Shepherd" the speaker is the shepherd himself, and he is trying to woo an un-named love interest by tempting her with bunches of fancy material possessions and lovely flowers. To gain a real sense of the speaker's perspective, read the reply that Sir Walter Raleigh wrote: "The Nymph's Reply to the Shepherd." You will notice a decidedly different tone. So, I would say the answer is D) the lovesick man.

Sorry if i'm wrong I studied this a couple of years ago and I only remeber somethings.

the reason some people sacrifice their own life for another person's life could be that they are in love with them and would do anything to keep them safe a protected even if that means risking their life in the process
