Based on this map, the proposed equal rights amendment was not added to the
Constitution because
(1) too few New England states supported it
(2) fewer than three-fourths of the states ratified it
(3) the president vetoed the passage of the amendment
(4) Idaho, Nebraska, and Kentucky never held a ratification vote
Assuming that this is referring to the same map that was posted before with this question, the response is "(4) Idaho, Nebraska, and Kentucky never held a ratification vote"
