Question

in the 1970s, the national organization for women expanded its goals by
backing a female candidate for the us presidency.
hiring phyllis schlafly to promote cultural equality.
supporting the equal rights amendment.
calling for required government childcare centers.

Explanation:

The National Organization for Women (NOW) expanded its feminist advocacy in the 1970s by pushing for broader social support systems. Backing a female presidential candidate was not a key 1970s expansion goal; Phyllis Schlafly opposed NOW's goals (she fought the ERA); while NOW supported the ERA, this was an earlier priority, and the 1970s expansion included pushing for government-supported childcare as part of broader gender equity efforts.

Answer:

calling for required government childcare centers.
