<span>The metaphor's meaning in this line is D) the speaker sees the daffodil's beauty as a priceless memory. The speaker emphasizes wealth as a lasting virtue in this stanza, and as such, is priceless. This word does not necessarily fit in with the rest of the poem, however, because it is mostly natural up until this point.</span>
I would personally recommend the Ben Carson interview simply because it is constantly updated unlike the Encyclopedia Britannica.
Also, taking into consideration the fact that the main focus should be learning about a modern hero is important to highlight the fact that The Encyclopedia provides facts and general information regarding past heroes and despite Carson's controversial opinions he has had plenty of experience interviewing modern day heroes therefore I consider he would be a great resource.
Hope this helps!
