Formula for answering multiple-choice questions:
I. Exclusion method
1. In multiple-choice questions, if there is a progressive relationship between two or more options, that is, these two or more options will be established at the same time, the correct item can only be found outside the above options.
2. In multiple-choice questions, if two or more options are similar or similar, that is, two or more options are established at the same time, the correct item can only be found outside the above options.
3. In multiple-choice questions, once a pair of contradictory options appear, the correct option often comes from these two opposing options.
Second, the causal analysis method
1, causal analysis, refers to the solution of causal multiple-choice questions, combining limbs and stems, specifically analyzing whether they constitute a causal relationship and making a correct judgment.
2. To correctly grasp the causal relationship between things, it is necessary to make clear that the cause and result are both the first and the second, and the relationship between cause and effect.
3. It should be noted that the causal relationship between things has many reasons, both objective and subjective; There are both fundamental reasons and general reasons; There are primary reasons and secondary reasons. Therefore, when solving problems, we must analyze the causal relationship between them according to the different requirements of the topics. To solve the causal problem by causal analysis, we should combine the problem limb with the problem stem, take the problem stem as the cause and select the limb as the fruit.
4. It should be noted that the third question of causality is not selected: first, those who answer irrelevant questions are not selected; Second, it is repeated with the stem or in disguised form; Third, those who cause and effect are reversed do not choose.
