How would you describe the narrator's questions as he views the urn's images in the fourth stanza of Ode on a Grecian Urn?

Who are these coming to the sacrifice?
To what green altar, O mysterious priest,
Lead'st thou that heifer lowing at the skies,
And all her silken flanks with garlands drest?
What little town by river or sea shore,
Or mountain-built with peaceful citadel,
Is emptied of this folk, this pious morn?
And, little town, thy streets for evermore
Will silent be, and not a soul to tell
Why thou art desolate, can e'er return.

A:He wonders why they are sacrificing a heifer.

B:He wonders who these people are, where they are from, and where they are going.
