Explanation:
Memorabilia from a lifetime could be used. If you think of each paragraph representing a shell, necklace, WWII helmet, letter, photograph, etc. Each would have their own purpose, relevance, and setting.
A participle has the form of verb + -ing. So the only such word here is 'smiling' that is the participle in this sentence. It modifies 'woman', that is, it refers to how the woman opened the door - smiling pleasantly.
