Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to
be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
All cabbages are beetroots.
Some cabbages are carrots.
Conclusions:
I. Some beetroots are cabbages.
II. Some beetroots are carrots.
This question requires us to evaluate two statements about vegetables and determine if the given conclusions logically follow from these statements. We need to assume the statements are true, regardless of real-world facts.
Statement 1: All cabbages are beetroots.
This is a universal affirmative statement. It means the entire set of 'cabbages' is contained within the larger set of 'beetroots'. If something is identified as a cabbage, it is automatically also a beetroot.
Symbolically, if $C$ denotes the set of cabbages and $B$ denotes the set of beetroots, this statement can be represented as: $ \forall x (C(x) \implies B(x)) $.
Statement 2: Some cabbages are carrots.
This is a particular affirmative statement. It indicates that there is at least one member that belongs to both the 'cabbages' set and the 'carrots' set. There is an intersection between these two categories.
Symbolically, if $R$ denotes the set of carrots, this statement is: $ \exists x (C(x) \land R(x)) $.
Conclusion I: Some beetroots are cabbages.
Based on Statement 1 ('All cabbages are beetroots'), we know that every cabbage is also a beetroot. This implies that the set of cabbages is a subset of the set of beetroots. Therefore, it must be true that at least some members of the 'beetroots' set are also members of the 'cabbages' set. This conclusion is a direct logical consequence of Statement 1.
From $ \forall x (C(x) \implies B(x)) $, it directly follows that $ \exists x (B(x) \land C(x)) $. Hence, Conclusion I logically follows.
Conclusion II: Some beetroots are carrots.
We use both statements here. Statement 2 tells us that 'Some cabbages are carrots', meaning there exists at least one entity that is both a cabbage and a carrot. Statement 1 tells us that 'All cabbages are beetroots'. Therefore, any entity that is both a cabbage and a carrot must also be a beetroot (since it is a cabbage). This establishes that there exists at least one entity that is both a beetroot and a carrot.
Combining $ \exists x (C(x) \land R(x)) $ (Statement 2) and $ \forall x (C(x) \implies B(x)) $ (Statement 1), we can deduce $ \exists x (B(x) \land R(x)) $. Hence, Conclusion II logically follows.
After analyzing both statements and evaluating each conclusion based on the rules of logic:
Therefore, both conclusions are valid deductions from the given statements.
