Very interesting DS. My pick is B.
Each correctional facility in a certain state has the same number of interns, and each facility has interns of each sex. If Lockwood Correctional Facility has 22% of the female interns in the state, does it have less than 20% of the male interns?
(1) Lockwood has between 18% and 22% of the state's male interns
(2) Lockwood has more female interns than does any other facility in the state.
St1: is clearly insuff. (EDITED LATER: how wrong I was... See the later post).
St2: First, we can conclude than each of the other facilities has less than 22% female interns in the state… Which means that there must be at least 5 facilities (including Lockwood one). Also, since the number of interns is the same for all facilities and Lockwood has more females than does any other one => Lockwood has less males than any other one => the Lockwood male interns should constitute less than 100%/5 = 20% of the male interns in the state (because if we assume they constitute 20% or more, it would mean that each of the other facilities would constitute more, and, in order not to exceed 100%, we would have to conclude that there’re less than 5 facilities =>contradiction). Sufficient.
What is the OA?
