1. A company builds a facial recognition system with an all-male development team. Post-release, the system performs significantly worse on female faces. The most likely cause is:

• Female faces are fundamentally harder for computers to recognize.
• The team intentionally designed the system to work poorly on female faces.
• The homogeneous team tested with faces similar to their own, creating an unrepresentative training and testing dataset.
• Female users are less likely to position their faces correctly for recognition.

2. Two programmers simultaneously edit the same file. Which tool most directly prevents one programmer’s changes from silently overwriting the other’s?

• A debugger, which finds errors in the combined code.
• Version control, which tracks changes and flags conflicts requiring human resolution.
• A compiler, which checks both versions for syntax errors.
• Documentation, which records what each programmer changed.

3. Consider statements about collaboration in computing:
I. Diverse teams are more likely to identify bugs related to accessibility and edge cases that affect underrepresented users.
II. Collaboration always produces better software than individual work.
III. Version control allows multiple programmers to work on the same codebase simultaneously without losing each other’s changes.

Which statements are correct?

• I only
• I and II only
• I and III only
• I, II, and III

4. For the AP CSP Create Task, which activity is permitted?

• Having a classmate write a procedure you include in your submission.
• Copying code from another student’s program with their permission.
• Discussing your program idea with a teacher and acknowledging their input in your written response.
• Using an AI to generate the code for your program.

5. Code review, where programmers read and comment on each other’s code before merging, primarily provides which benefit?

• It speeds up development by parallelizing the coding process.
• It catches errors and enforces quality standards before code reaches the codebase.
• It automatically fixes bugs found during the review.
• It replaces the need for testing by verifying correctness through reading.

6. Which scenario best illustrates how diverse teams reduce algorithmic bias?

• A team with members from different universities produces more original research.
• A team including users with visual impairments identifies that the app’s color-only error indicators are inaccessible, adding text labels before release.
• A large team writes more total code than a small team.
• A team that disagrees more often takes longer to ship features.
