Final answer:
The temporal transitions in the excerpt from Sherlock Holmes indicate a time relationship between events and actions.
Step-by-step explanation:
The temporal transition words in the excerpt from "The Adventures of Sherlock Holmes" by Sir Arthur Conan Doyle are "shortly after" and "however long." Temporal transitions are words or phrases that indicate a time relationship between events or actions. In this case, "shortly after" indicates that the character left the house not long after 8 o'clock in the morning, while "however long" suggests that the character is willing to wait for the person, regardless of how much time it takes. These transitions help to establish a sense of time and sequence in the narrative.
