Fill-in-the-blank questions are standardized and objective questions with unique answers. However, in the actual exam, candidates may give different answers due to differences in understanding and expression. Therefore, for fill-in-the-blank questions, the correctness of the answer is the primary consideration, while the uniqueness of the answer is relatively secondary. In the process of preparing for the exam, candidates should pay attention to mastering basic concepts and problem-solving methods to ensure that they can get correct answers accurately and quickly in the exam.
