I remember this from Kaplan
. When using "order" words like
[ require - request - order - ask .. etc ]
the rule of thumb is : [order word] + "that" + subject + "be"
Here only answer choice A uses it correctly
that pay be the same for jobs historically held by women as for jobs requiring comparable skill that are
[ order word ] : requires
the word that should appear next, so cross out choices C,D, and E
subject : pay
only choice A uses the verb "be"
