Editorial: To qualify as an effective law, as opposed to merely an impressive declaration, a command must be backed up by an effective enforcement mechanism. That is why societies have police. The power of the police to enforce a society’s laws makes those laws effective. But there is currently no international police force. Hence, what is called “international law” is not effective law.
Which one of the following is an assumption required by the editorial’s argument?
(A) No one obeys a command unless mechanisms exist to compel obedience.
(B) If an international police force were established, then so-called international law would become effective law.
(C) The only difference between international law and the law of an individual society is the former’s lack of an effective enforcement mechanism.
(D) The primary purpose of a police force is to enforce the laws of the society.
(E) Only an international police force could effectively enforce international law.
EXPLANATION FROM Fox LSAT
Hmm. Maybe a diagram?
- Premise 1: Effective Law —> Effective Enforcement Mechanism
- Premise 2: Police are one Effective Enforcement Mechanism
- Conclusion:
International Police Force —> International Law Effective
The problem here is that police are
sufficient for enforcement, but that doesn’t mean they’re
necessary for effective enforcement (i.e., they are not the only effective enforcement mechanism).
So the argument seems to have assumed that one effective enforcement mechanism is the
only effective enforcement mechanism. It has assumed that a sufficient condition has to be a necessary condition.
A) This is way too big and broad to be the answer for a necessary assumption question. The argument was entirely about international law. It never said anything about people not cheating at Scrabble against your granny, even though you could get away with it, just because it’s more fun not to cheat. This ain’t it.
B) The conclusion implied that an international police force was
necessary, but didn’t say that laws couldn’t still fail to be effective, even if there
was a police force. (Remember, there can be many necessary conditions, lack of any one of which could cause something to fail. For example, maybe in order for a law to work, it also can’t be stupid (the prohibition of marijuana is stupid, that’s why nobody follows the law, regardless of whether or not there’s an effective enforcement mechanism), or for another example, suppose there was an international police force but it wasn’t willing to go to war with the U.S. or China, so the U.S. and China could just ignore whatever international laws they didn’t want to follow, international police force be damned. Anyway, this is not the answer.
C) The argument doesn’t assume that there aren’t other differences between international law and domestic law. Not even close.
D) The “primary purpose” of a police force could be simply to show off; the argument doesn’t tell us whether there are other purposes or not.
E) Yep. This
must be true for the argument to make sense, which means it’s necessary. If this answer is not true, then there are other ways to effectively enforce international law, which would destroy the conclusion of the argument. This is what we predicted, and it’s our answer.
The answer is E.
