The domain for variable \( x \) is the set of applicants for employment. Define the predicates:

- \( R(x) \): \( x \) brought a resume to the interview
- \( N(x) \): \( x \) arrived on time for the interview
- \( J(x) \): \( x \) got the job

Select the logical expression that is equivalent to:

"Every applicant who did not come on time for the interview or did not bring a resume did not get the job."

1. \(\forall x(\lnot N(x) \rightarrow (\lnot R(x) \rightarrow \lnot J(x)))\)

2. \(\forall x((\lnot N(x) \lor \lnot R(x)) \rightarrow \lnot J(x))\)

3. \(\forall x(\lnot N(x) \land \lnot R(x) \rightarrow \lnot J(x))\)

4. \(\forall x((\lnot N(x) \lor \lnot R(x)) \land \lnot J(x))\)
