Step 1: Understanding unaccusative verbs.
Unaccusative verbs are intransitive verbs where the subject undergoes the action rather than performing it. They often describe a change of state or movement and originate from a deep structure object position.
Step 2: Classifying the options.
(A) "Hulk ran": Agentive; Hulk is performing the action. → Not unaccusative.
(B) "Hulk stumbled": Involuntary motion; Hulk undergoes the event. → Unaccusative.
(C) "Hulk joked": Volitional action; Hulk is the agent. → Not unaccusative.
(D) "Hulk collapsed": Involuntary change of state; Hulk undergoes the action. → Unaccusative.

S1: If X is an adjunct of Y, then Y is an argument of X because the presence of Y in a sentence is necessary for X to occur.
S2: It is not necessarily true that if Y is an argument of X, then X is Y's adjunct.
Given the sentences S1 and S2, choose the option that explains why S2 cannot be derived from S1.
S1: Deadpool was interested in Wolverine's description of morphosyntax.
