Final answer:
Details (a), (b), and (c) demonstrate that the narrator is practical because they suggest the narrator plans carefully, considers consequences, and uses logic and common sense, which are characteristics of a practical individual.
Step-by-step explanation:
To determine which details show that the narrator is practical in a text, we must look for evidence of careful planning, consideration of consequences, and logic-based decision-making. Detail (a), plans their actions carefully, and detail (b), considers the consequences of their actions, both suggest a methodical and reasoned approach to situations. Detail (c), uses logic and common sense in decision-making, further supports the idea that the narrator is practical, as they do not act on impulse but rather use reason to guide their actions. Conversely, detail (d), guided by emotions and intuition, is not typically associated with being practical, as it implies an approach that is less systematic and more spontaneous.
For a real-world application of practical decision-making, one can refer to cognitive skills and heuristics in solving complex problems, and strategic consideration of all available options in political decision-making as practical approaches to situations requiring thoughtful analysis.
