(A)Increase the credit score requirement from 700 to 750 to be more selective.(B)Rewrite the algorithm in a different programming language.(C)Analyze the preferredZipCodeList to determine if it unfairly excludes certain communities and consider removing that condition.(D)Ensure that the application data is encrypted before being processed.

9. A company develops a hiring tool that uses machine learning to screen résumés. The tool is trained on a dataset of résumés from the company's successful employees over the last 20 years. If the company historically hired more men than women, what is a likely outcome of using this tool?

(A)The tool will be completely objective because it is a computer algorithm.(B)The tool will learn to favor résumés from male candidates, reflecting the bias in the training data.(C)The tool will correct for the historical imbalance and favor résumés from female candidates.(D)The tool will be unable to process résumés from female candidates due to a lack of data.

10. A weather research institute develops a mobile app that allows users to submit local weather observations, such as temperature and cloud cover, from their current location.

12. A software developer creates a new video game and wants to allow others to freely share and even modify the game, as long as they give her credit and do not use it for commercial purposes. Which of the following would be the most appropriate legal tool for her to use?

13. A student finds a program online that solves a difficult problem for their computer science class. The student copies the code, changes the variable names, and submits it as their own work without citing the original source. This is an example of which of the following?

(A)Open source development(B)Phishing(C)Crowdsourcing(D)Plagiarism
