A
test case generation
support system 30 comprising an arithmetic unit 31 that executes: open-ended
response generation processing for generating an open-ended response corresponding to an open-ended question for a predetermined topic which requires a response by inputting the open-ended question to a trained model 47; first closed-ended
question generation processing for generating a first closed-ended question by inputting the open-ended question and the open-ended response to the trained model 47, the first closed-ended
question asking whether the open-ended response is correct or incorrect and requiring that the open-ended response is correct as a correct answer; and second closed-ended
question generation processing for changing a topic portion of the first closed-ended question by a predetermined
algorithm and generating a second closed-ended
question asking whether the changed topic portion is correct or incorrect.
