Comprehensive reasoning question type involves multiple knowledge points in inevitability reasoning. Compared with the question types that test a single knowledge point, this type of question type is relatively more difficult, and it is often tested in provincial examinations in recent years. So how do candidates find a "breakthrough" to solve the problem when they encounter this type of question?

Now take a question as an example:

examples

A candidate is filling out his application, including law, management, economy, finance, audit and accounting 6 There are majors for choice, but the application you fill in must meet the following conditions:

(1) If you fill in the legal major, then you will not fill in the management major, but you will need to fill in the accounting major;

(2) Only when you don’t fill in the audit major, you will only fill in the finance or economic major;

(3) If you don’t fill in the economic major, then you will not fill in the accounting major;

(4) The law major has always been the major you want to study, so you must fill in it.

This can be used to introduce the candidate:

A. Fill in the finance and economics major

B. Both the management and economics major did not fill in the

C. Fill in the law major, and also fill in the finance major

D. Fill in the accounting major, but did not fill in the audit major

[Zhonggong Analysis] D. According to the conditions of the question, we can obtain: ① Law ⇒ Non-management and accounting; ② Financial or economic ⇒ Non-auditor; ③ Non-economic ⇒ Non-accounting; ④ Law. Through these four conditions, we can find that compared with the other three conditions, the situation of the condition ④ is determined, so we can start from the condition ④, and then we can find that both the condition ④ and the condition ① mentioned the legal profession, which is related. You can use the hypothesis proposition reasoning rules. You must be willing to be willing to be willing to be unfaith, and no after, no before. Therefore, from ④ and ①, you can introduce the management major and the accounting major; combined with ③, you can know that if you apply for the accounting major, you must apply for the economic major; combined with ②, you can know that if you apply for the economic major, you cannot apply for the audit major, and the financial major is uncertain. Therefore, choose D for the answer.

[Analysis tips] We can find that the question stem involves multiple inevitable reasoning points such as false propositions and selective propositions. Then this type of question is a comprehensive reasoning question. When encountering comprehensive reasoning problems, you need to pay attention to the correlation between the determined information and conditions. Taking this question as an example, the first three conditions are hypothetical propositions, and there is uncertainty, but the application law for the fourth condition is determined, that is, there is only one situation, so we can start with the determined conditions. Then we can find that both Condition 4 and Condition 1 mention the legal major, and the two conditions are related, that is, there is common information between conditions and conditions. From this, we can see that Condition 1 and Condition 2 have the common information of accounting major, and Condition 2 and Condition 3 have the common information of economic major, so it is also related.

When you understand the correlation between the determined information and the conditions, start with the determined information of the condition four, and then use the correlation between the condition four and the condition one, and then use the correlation between the condition one and the condition two, condition three and condition two to deduce it step by step.

[Summary] When doing comprehensive reasoning questions, pay special attention to the correlation between the determined information and conditions.

Recently, a community launched a unique community cultural activity to activate the community cultural atmosphere, and several interest clubs are available for residents to choose from. The known registration situation is as follows:

(1) Residents participated in at least one of the poetry clubs and calligraphy clubs.

(2) If residents participate in the poetry club, they do not participate in the choir.

(3)Ms. Li participated in the choir.

The community director learned about the above situation and concluded that Ms. Li also participated in the drama fan club.

Which of the following items is true, can it become the prerequisite for the community director to determine?

A. Ms. Li did not participate in the Poetry Club. B. Those who participated in the Theatre Fan Club also participated in the Calligraphy Club

C. Ms. Li did not participate in the Calligraphy Club. D. Those who did not participate in the Theatre Fan Club did not participate in the Calligraphy Club

[Answer] D. questions: ①Either join the poetry club or participate in the calligraphy club; ②Either join the poetry club ⇒Without joining the choir; ③Ms. Li participated in the choir.Through these three conditions, we can find that compared with the other two conditions, the situation of the condition ③ is determined, so we can start from the condition ③, and then we can find that both the condition ③ and the condition ② mention the choir, which is related. Combined with the latter part of ③, the negative front part can be drawn, that is, Ms. Li did not participate in the poetry club, and because ① and ② are related, it can be seen that Ms. Li must have participated in the calligraphy club.

A item, combined with the reasoning of the question, it is impossible to determine whether Ms. Li participated in the Poetry Club without participating in the Poetry Club, and it is not a prerequisite for the community director to determine.

B item, reasoning relationship: Participated in the drama fan club ⇒ Participated in the calligraphy club. According to the reasoning in the question, it can be seen that Ms. Li participated in the calligraphy club and confirmed that the latter part could not be effective inference, which was not a prerequisite for the community director to make a conclusion.

C item. According to the reasoning of the question, it can be seen that Ms. Li must have participated in the calligraphy club. The contradiction with this item is not a prerequisite for the community director to determine.

D item, reasoning relationship: do not participate in the drama fan club ⇒ do not participate in the calligraphy club. According to the reasoning of the question, it can be seen that Ms. Li participated in the calligraphy club, and the negative last item can be issued, that is, Ms. Li participated in the drama fan club, which is the prerequisite required by the community director to make a decision.

Therefore, this question is D.

and above are related to how to find a "breakthrough" in comprehensive reasoning. "Just say but not practice fake style" candidates also need to practice a lot of questions to practice "fire eyes". Zhonggong Education wishes everyone good results!
