                          質問 # 24
                          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.

                          正解：D

                          解説：
                          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.


                          質問 # 25
                          Which of the following code snippets will output Truefor both printfunctions by correctly identifying the type of each variable and performing valid operations?

                          正解：D

                          解説：
                          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.


                          質問 # 26
                          You are creating a presentation slide to communicate findings about student stress levels across four categories over a six-month period. You include the following line graph in your presentation:

                          Your goal is to help your audience clearly understand trends in stress levels over time.
                          What is the highest problem with this visual presentation? Select the best answer.

                          正解：E

                          解説：
                          The lines are very light and visually similar, making it difficult to clearly distinguish between the different stress level trends, which directly reduces the effectiveness of the visualization in communicating patterns over time.


                          質問 # 27
                          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.

                          正解：B

                          解説：
                          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.


                          質問 # 28
                          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.

                          正解：C

                          解説：
                          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.


                          質問 # 29
                          ......
