Question

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 : 

1. All flowers are tulips.

2. No tulips are whites.

Conclusions :

I. All tulips are flowers.

II. Some tulips are whites.

The correct answer is

Neither conclusion I nor conclusion II follows.

Statement Analysis

First, let's break down the meaning of the given statements to understand the relationships between the categories involved (flowers, tulips, whites).

Understanding Statement 1: All flowers are tulips.

This statement tells us that every single item that belongs to the category 'flowers' also belongs to the category 'tulips'. Essentially, the set of 'flowers' is completely contained within the set of 'tulips'. We can represent this relationship using set notation as: $Flowers \subseteq Tulips$. This means if something is a flower, it must be a tulip, but it doesn't exclude the possibility that there are tulips which are not flowers.

Understanding Statement 2: No tulips are whites.

This statement establishes a complete separation between the category 'tulips' and the category 'whites'. It means that there is no overlap between these two sets. An item cannot be both a tulip and white at the same time. Using set notation, this relationship is represented as: $Tulips \cap Whites = \emptyset$.

Conclusion Evaluation

Next, we need to determine if the given conclusions logically follow from the two statements. We will examine each conclusion individually.

Evaluating Conclusion I: All tulips are flowers.

Statement 1 states that All flowers are tulips ($Flowers \subseteq Tulips$). This tells us about flowers being a subset of tulips. However, it does not provide information in the reverse direction. Just because all flowers are tulips doesn't mean all tulips must be flowers. There could be tulips that are not flowers. Therefore, the conclusion All tulips are flowers ($Tulips \subseteq Flowers$) does not logically follow from Statement 1.

Evaluating Conclusion II: Some tulips are whites.

Statement 2 clearly states No tulips are whites ($Tulips \cap Whites = \emptyset$). This means the intersection of the set of tulips and the set of whites is empty. Conclusion II, which states Some tulips are whites, implies that there is at least one tulip that is also white ($Tulips \cap Whites \neq \emptyset$). This conclusion directly contradicts Statement 2. Therefore, Conclusion II cannot logically follow from the given statements.

Overall Determination

After analyzing both statements and conclusions:

  • Conclusion I does not logically follow because the statement "All flowers are tulips" does not guarantee that "All tulips are flowers".
  • Conclusion II is invalid because it directly contradicts the statement "No tulips are whites".

Since neither Conclusion I nor Conclusion II can be logically derived from the provided statements, the correct option is the one indicating that neither conclusion follows.
