Final answer:
The provided passages do not clearly specify what happened after Trevor's mother found a 'present' in the trash, as the passages discuss other characters and their related events.
Step-by-step explanation:
The passage you've presented is not directly connected with the discovery of a 'present' in the trash; rather, it provides diverse, fragmented scenarios concerning different characters and events, such as McTeague receiving a dental sign from Trina as a birthday present or the events following a pursuit and finding marijuana bundles. Looking at these contexts, it's possible that the 'present' found in the trash, which is not explicitly detailed here, leads to the events with McTeague's birthday, Trina's wedding, or Jane's preparation of a pack, depending on which character and which story the question refers to.
