What do you think the speaker refers to when he says “If you had known what I know”?

when i skim a text i look for anything i'm trying to find, like keys or clues or i just want to see if it is interesting to me.

explanation:

the answer is actually c   i just got done with the test.

journalism is the gathering, organizing, and distribution of news -- to include feature stories and commentary -- through the wide variety of print and non-print media outlets. it is not a recent phenomenon, by any means; the earliest reference to a journalistic product comes from rome circa 59 b.c., when news was recorded in a circular called the acta diurna. it enjoyed daily publication and was hung strategically throughout the city for all to read, or for those who were able to read.

choices ? or is this a actual question from yourself ?
