Advanced grammar involves understanding the nuances of epistemic modality and the restrictive nature of relative clauses. Mark T (True) or F (False) for the statements regarding these structures.

(__)The modal verb "must" in "He must be exhausted after the marathon" expresses epistemic necessity (logical deduction), not obligation.
(__)In the sentence "The theory, that I described earlier, is complex," the use of "that" is grammatically correct for a non-restrictive clause.
(__)The pronoun "whom" is mandatory, in formal English, when it functions as the complement of a preposition (e.g., "The person to whom I spoke").
(__)The conjunction "lest" is followed by the subjunctive mood or "should", expressing a negative purpose (e.g., "Lest he forget").

Select the alternative that presents the correct sequence, from top to bottom.
