Statement (I): All children are students. All students are players. Which of the conclusions follow from the given statements?
Conclusions (I): All students are children.
(II): All children are players.
(b) Only II follows
The problem presents a set of statements and conclusions related to categories, a common type of logical reasoning question known as syllogism. We need to determine which of the given conclusions logically follows from the provided statements.
Let's evaluate each conclusion based on the logical relationships established by the statements.
Statement (I) tells us "All children are students" (\(C \subseteq S\)). This does not automatically mean that "All students are children" (\(S \subseteq C\)). There could be students who are not children (e.g., adult students). The statement only guarantees that every member of the 'children' group is also a member of the 'students' group, not the other way around. Therefore, Conclusion (I) does not necessarily follow from the given statements.
We have two statements:
If every child is a student, and every student is a player, then it logically follows that every child must also be a player. This is a basic property of set theory or logical deduction known as transitivity. If set A is a subset of set B, and set B is a subset of set C, then set A is a subset of set C. In our case, A=Children, B=Students, and C=Players.
\(C \subseteq S\) and \(S \subseteq P\) implies \(C \subseteq P\).
Therefore, Conclusion (II) "All children are players" logically follows from the given statements.
Based on our analysis:
Thus, only Conclusion (II) follows from the given statements.
| Statement/Conclusion | Logical Representation | Follows? | Reasoning |
|---|---|---|---|
| Statement (I): All children are students | \(C \subseteq S\) | Given | Provided statement |
| Statement (II): All students are players | \(S \subseteq P\) | Given | Provided statement |
| Conclusion (I): All students are children | \(S \subseteq C\) | No | \(C \subseteq S\) does not imply \(S \subseteq C\). Counter-example exists. |
| Conclusion (II): All children are players | \(C \subseteq P\) | Yes | Follows from transitivity: \(C \subseteq S\) and \(S \subseteq P \implies C \subseteq P\). |
Syllogism is a type of logical argument that applies deductive reasoning to arrive at a conclusion based on two or more propositions that are assumed to be true (statements). A typical syllogism consists of three parts: a major premise, a minor premise, and a conclusion.
Categorical syllogisms, like the one here, deal with categories or classes of things. Common forms include "All A are B," "No A are B," "Some A are B," and "Some A are not B." The relationships between these categories can often be visualized using Venn diagrams to check the validity of conclusions.
In this specific case, the structure is of the form:
This is a fundamental valid argument form in logic.
Statement: Money plays a vital role in politics.
Conclusion I: The poor can never become politicians.
Conclusion II: All the rich men take part in politics.
Which of them logically follows from the information given in the statement?
Statements:
(A) All Principals are men
(B) Some Women are Principals
(C) All humans are women
Conclusions:
(I) All humans are men
(II) Some humans are women
(III) Some men are Principals
(IV) All women are men
Choose the correct conclusion:
Statements:
Some Bottles are Papers
Some Papers are pens
No Pen is Pencil
Conclusions:
(I) Some Bottles are Pencil
(II) No Bottle is pencil
(III) Some Bottles are pencil
Which conclusion(s) follow?
Given below are two statements: one is labeled as Assertion (A) and the other is labeled as Reason (R). Assertion (A): Milk production in India is low as compared to many countries of the world. Reason (R): The animal rearers in India are poor. In the light of the above statements, choose the most appropriate answer:
Statement: European economy is dependent mainly on forests. Conclusions: (I) Europe wants only maintenance of forests to improve economic conditions. (II) Trees should be preserved to improve the European economy. Which conclusion will follow on the basis of the given statement?
