Interfere is my guess as per the context, so option B matches here.

This is a question of the Manhattan GRE diagnostic exam.

I would recommend not to post such questions cuz affects the ones who haven't dont it yet.

The clue phrase in the first part of the stem is "spheres of human conduct carefully delineated and harmonized," implying that the modern legal system defines the boundaries of human behaviors to promote the peaceful coexistence of these behaviors. In other words, the modern legal system serves to keep people out of others' space. The second part of the stem should conform to this concept.

Thus, the second part of the stem should mean "one person's freedom ends where it begins to infringe on" another person's freedom. An appropriate Filler is infringe on, which means "to encroach on."

(A) Constitute sounds like Constitution, which is a theme trap if you're thinking of the relationship between the Constitution and the legal system.

(B) CORRECT. Impinge upon means the same thing as infringe on.

(C) Decimate means "to destroy." This has an appropriately negative spin, but it's much too strong for what we're looking for.

(D) Dampen is an easy, familiar word, but it's not close enough in meaning to infringe on.

(E) Rule over is not close in meaning, but it does contain a theme trap if you're thinking of the "rule of law."
