   2. In a single file on the system

   3. On a remote server automatically

   4. In the Python installation folder

2. What are breakpoints and watches used for in software development?

   1. To compile source code into machine code

   2. To analyze program behavior and examine data at specific points

   3. To format Python source code automatically

   4. To speed up the execution of loops

3. On what are predictions in predictive modeling based?

   1. Guaranteed certainty

   2. Probability

   3. Fixed rules without variation

   4. Raw feature counts

4. When does a function linked to an event run?

   1. Continuously while the application is open

   2. Before the GUI window loads

   3. Only when the event happens

   4. When the program is compiled

5. What are breakpoints defined as in IDEs like PyCharm or VS Code?

   1. Keywords that stop program compilation

   2. Variables that store error logs

   3. Markers that pause program execution at a chosen line of code

   4. Functions that return calculated values

6. Predicting a student's final grade using past marks, attendance, and study hours is an example of what?

   1. Causation

   2. Prediction

   3. Hyperparameter tuning

   4. Model validation

7. GUIs improve usability primarily by providing:

   3. False Positives (FP)

   4. False Negatives (FN)

10. What elements characterize a clean interface?

    1. Well-arranged widgets and enough space between them

    2. Heavy graphical animations and fast network speeds

    3. Database connections and complex backend logic

    4. Full-screen background images and dark themes

11. What feeds directly into the Tuning stage?

    1. Collecting configuration and refining tunings

    2. Deleting database records

    3. Generating syntax errors

    4. Creating breakpoints

12. A commonly used tool for machine learning and data analysis is:

    1. MS Word

    2. Python

    3. PowerPoint

    4. Notepad
