Answer:
Lines 38-39 (“Grow up . . . wants”)
Step-by-step explanation:
Correct. The speaker’s advice to “Grow up and join the big, busy crowd / That scrambles for what it thinks it wants” (lines 38-39) follows his advice that “this is no time nor place for a poet” (line 37). By putting the crowd in opposition to poets and saying it “scrambles for what it thinks it wants” (line 39), the speaker implies that the nonpoets are undignified and misguided in their desires.
