assign the stereochemical configuration of the selected tetrahedral carbon chiral centers (R, S or N (not a chiral center)) and the alkene (E, Z or N (not a stereocenter)) that are indicated by the arrows (note that you do not have to assign the configuration of every chiral center in the molecule). If the atom in question is not a chiral center or is not a stereocenter circle N for neither.
