Abstract: The automatic generation of multiple-choice questions, whose subtasks include cutting-edge tasks such as question generation, answer generation, and distractor generation, is a new difficulty in the NLP field. Although previous studies have done on these three subtasks, few studies have tried to unify them. A multiple-choice question automatic generation model was proposed, theoretical analysis was made on the model’s question generation, answer generation, and distractor generation modules, and experiments on automatic question generation and answer generation based on T5 was conducted. The experiments showed that this model can generate multiple-choice questions based on user input text, and the question quality was about 1 point higher than the BLEU against the pure T5 model, and other metrics are also slightly improved. A theoretical analysis was made on the generation of distractor.

Key words: multiple-choice questions, question generation, T5 model
