In the second example, "only Jedi use the Force" is translated into F -> J. Is this the equivalent to saying "One uses the Force only if they are a Jedi"?

I was under the impression that "only" and "only if" are two completely different ideas, with "only" indicating a group one translation and "only if" indicating a Group 2 translation. Are they both group 2 indicators in that case? Can someone please clarify?

For question #8, if I translated it as:

Domain: countries w nationalized health insurance

Translation: req-treat --> / denied

would this still be correct? Is the assumption that /denied = receive something that's necessary on the LSAT?
