How did this segment help
you to better understand the
book and the author?

even though there may be variations in human emotions over time, the poem “ a contribution to statistics” by wislawa symborska suggests that the only unchangeable characteristic is mortality.

the author poses a distinction between the approximate and non-approximate numbers which correspond to our need for certainty in life and the difficulty of achieving it. our efforts to measure the exact often fail because the world is not always clearly structured .the poem seems to imply   that the only thing that is certain and has an exact number is death.  

you did not give us a excerpt to read or any statements to choose from so we can not know the right answer be more detailed when asking your question

it would be nice to see the passage but with my understanding of the word oxymoron they speaker is saying that love is contradictory.
