The symbol i chose was folded papers. Folded papers in this story symbolized the lottery tickets that were in the black box. Each folded paper was a chance of getting the black dot which had to do with death. You can see in page 27 line 73-74 that Mr Summers was able to change out wood chips for slips of paper.
For Imagery i chose the smoothest roundest stone. This is imagery because of the way its describing the stone in detail. It shows that the stones that were chosen were the roundest and smoothest ones they can find. This can be found on page 25 line 17.
For figure of speech i chose "the feeling of liberty sat uneasily on most of them". I chose this because it is personification, its giving human traits. It basically means that the feeling of freedom didn't feel comfortable to most of them. This quote can be found page 25 and line 12-13.
