   A team is testing an AI-based recommendation system. The parameters are: user location (US, EU, Asia), device type (mobile, desktop), and content category (news, sports, entertainment). The team has a budget of 10 test cases. They want to apply pairwise testing but are concerned about coverage. What is the most appropriate action?

   • AGenerate a pairwise test set and verify it covers all pairs within the budget
   • BRun 10 random test cases instead of pairwise
   • CReduce the number of values for each parameter to fit the budget
   • DUse exhaustive testing because the budget is too small

   A team is testing a speech-recognition model. The input parameters are: accent (American, British, Australian), background noise (quiet, noisy), and audio quality (low, high). The team wants to apply pairwise testing but has a limited test budget. What is the most important consideration when identifying the values for each parameter?

   • AInclude as many values as possible for each parameter
   • BUse the same number of values for each parameter
   • CInclude values that are representative of real-world usage
   • DUse only the most common value for each parameter
