Nature's first green is gold, Her hardest hue to hold. Her early leaf's a flower; But only so an hour. Then leaf subsides to leaf. So Eden sank to grief, So dawn goes down to day. Nothing gold can stay. Which best describes the effect of allusion on the meaning in this excerpt?

The following line, "Her hardest hue to hold," indicates that maintaining the innocent of the initial greens is the most difficult things to accomplish and he adds, "Her first leaf's a blossom / only so an evening." This is the third time he uses an analogy, suggesting that a blade is a bloom (and green is gold).
