Explanation:
This task involves determining the time range during which a person could have visited a specific location based on the times they were observed at other locations. The goal is to identify the time range when the person could have visited the target location without being observed. This requires careful tracking of the times and locations of the person and the other individuals involved.

Analyzing the Task:
1. Understanding the Scenario: The input text provides a scenario with a person (Nancy, Jessica, Susan, William, or Ashley) and a target location (bookstore, restaurant, art studio).

2. Identifying the Time Ranges: Each person is observed at various locations at specific times. These time ranges need to be recorded and analyzed to determine the time range when the person could have visited the target location.

3. [Important] Identifying the Gaps: The goal is to identify the time range when the person could have visited the target location without being observed. This requires identifying gaps in the observed time ranges.

4. Extracting the Final Query: After analyzing the time ranges, the question usually asks for the time range when the person could have visited the target location.

Constructing the Code Prompt:
1. Identifying the Person and Target Location: Parse the input text to determine the person and target location.

2. Parsing Time Ranges: Extract the time ranges from the input text. Each time range will need to be processed in the order they occur.

3. [Important] Identifying Gaps: Iterate over each time range and identify gaps in the observed time ranges. This is a crucial step that ensures the current state is always up-to-date.

4. Extracting the Final Question: After processing all time ranges, identify the specific question asked in the input text.

5. Examining Options: Review and display the options provided in the input text for the final question.

6. Determining the Answer: Based on the identified gaps, select the correct option that answers the question.
