1. Problem solving (1- 15): The problem solving is multiple choice, and one of the five choices is single choice.
Second, conditional adequacy judgment (16-25): Conditional adequacy judgment is a new type of question, which has a stem and then two conditions: condition (1) and condition (2).
(a) The condition (1) is sufficient, but the condition (2) is not.
(b) Condition (2) is sufficient, but condition (1) is not.
(c) Conditions (1) and (2) alone are not enough, but the combination of conditions (1) and (2) is sufficient.
(d) The condition (1) is sufficient, and the condition (2) is also sufficient.
(e) Conditions (1) and (2) alone are not enough, but the combination of conditions (1) and (2) is not enough.
Solving problems is relatively easy, as long as the knowledge points are basically correct, but it will be more difficult to judge the adequacy of conditions. It's a logic problem in mathematics, which involves both mathematics and logic. There are many pitfalls. Students should practice the judgment of the adequacy of conditions when reviewing.
