                          問題 #22
                          Below are six possible summaries for your presentation:
                          - Summary 1: "The data revealed a moderate positive correlation between age and recycling frequency. While 72% of students reported recycling paper regularly, only 39% reported recycling plastic."
                          - Summary 2: "Analysis showed notable differences in recycling habits by material type, with paper being most recycled and plastic least recycled."
                          - Summary 3: "Older kids recycled more than younger ones. Paper was the most recycled item- plastic got forgotten a lot."
                          - Summary 4: "Student responses showed positive environmental habits overall, though participation varied by waste type."
                          - Summary 5: "A lot of students said they recycle. Some didn't answer every question, so we couldn't figure out everything."
                          - Summary 6: "We asked more than 300 students about recycling. Most said they recycle paper, but way fewer recycle plastic." Which communication style is the best fit for Group A (data scientists) and Group B (12-year- olds), respectively? Select the best answer.

                          答案：E

                          解題說明：
                          The first summary uses precise statistical language and quantitative detail appropriate for data scientists. The third summary uses simpler, more conversational language that is easier for 12- year-olds to understand.


                          問題 #23
                          You have a list of test scores, where each entry includes a student name and a score. Some students appear more than once. You want to compute the average score for each student and store the results in a dictionary. Here's the partial code block:

                          Which code correctly replaces the # MISSING CODE comment to calculate the average score for each student? Select the best answer.

                          答案：D

                          解題說明：
                          It iterates through each record, extracts the name and score, and uses dictionary .get() to accumulate total scores and counts per student safely, initializing missing keys to zero. This correctly enables calculation of each student's average afterward.


                          問題 #24
                          An online retailer collects customer reviews, order transaction logs, and product ratings.
                          Which of the following correctly classifies these types of data? Select the best answer.

                          答案：B

                          解題說明：
                          Product ratings are numeric values stored in fixed fields, making them quantitative and structured.
                          Customer reviews are free-text responses, which are qualitative and unstructured. Transaction logs consist of organized records with defined fields such as order ID, date, and amount, making them structured and quantitative.


                          問題 #25
                          You are writing a function named process_data()to read and process numerical input from a file. The function must:
                          - read the file data.txt,
                          - attempt to convert the first line into an integer,
                          - handle file, conversion, or index-related exceptions,
                          - print the value only if no error occurs,
                          - and always print a final message after execution.
                          Which implementation correctly and robustly meets all these conditions? Select the best answer.

                          答案：C

                          解題說明：
                          It wraps file reading and integer conversion in a try block, catches the relevant file, conversion, and indexing exceptions, prints the value only in the no-error path using an else block, and uses a finally block to always print the final message.


                          問題 #26
                          Which of the following code snippets will output Truefor both printfunctions by correctly identifying the type of each variable and performing valid operations?

                          答案：C

                          解題說明：
                          Adding an integer and a float produces a float result, so checking that the type of the sum is float evaluates to True. The variable holding 3.0 is a float, so the isinstance check for float also evaluates to True.


                          問題 #27
                          ......
