OE
The words for the blank should match the clue “to metaphorically separate the wheat from the chaff.” (Chaff is the inedible part of wheat that is discarded before the wheat can be made into flour, so this expression means to separate out the useful and non-useful, or important and unimportant, parts of something.) You can also use the clues regarding “the only way that a person can function” given an “influx of information.” “Delete” and “eliminate” are attractive traps but don’t match the idea of separating the important parts from the unimportant. Only “triage” (think of what emergency room nurses do) and “prioritize” match. “Respond” and “requite,” which means to reciprocate, are not good fits.
