Verbal Reasoning – Syllogisms. “Some roses are red.”

Question:

All roses are flowers. Some flowers are red. Therefore, some roses are red. True or False?

Answer:

False (The conclusion does not necessarily follow from the premises)

The conclusion “Therefore, some roses are red” is false because it does not logically follow from the given premises. Here’s a detailed explanation:

Premises:

1. All roses are flowers.
2. Some flowers are red.

Conclusion:

Some roses are red.

Logical Analysis:

• Premise 1 tells us that every rose is a type of flower. This means the set of roses is entirely contained within the set of flowers.
• Premise 2 tells us that within the set of all flowers, there are some flowers that are red. However, it does not specify which flowers are red or whether these red flowers include roses.

Why the Conclusion that “Some roses are red” is False:

The conclusion assumes that because some flowers are red, some of those red flowers must be roses. However, this is not necessarily true. The red flowers mentioned in Premise 2 could be any type of flower other than roses.

For the conclusion to be true, we would need additional information directly linking roses to being red. For example, if we had a premise stating “Some roses are red,” then the conclusion would logically follow. However, with the given premises, there is no such direct link.

Example to Illustrate:

Consider this scenario:

• Suppose there are 100 flowers: 50 roses (all of which are white) and 50 tulips (25 of which are red and 25 are yellow).
• According to Premise 1, all 50 roses are flowers.
• According to Premise 2, some of the 100 flowers are red (specifically, the 25 red tulips).

In this scenario:

• All roses are flowers (Premise 1 is satisfied).
• Some flowers are red (Premise 2 is satisfied because there are 25 red tulips).

However, none of the red flowers are roses; they are all tulips. Therefore, it is possible for Premise 1 and Premise 2 to be true while the conclusion “some roses are red” is false.

Conclusion:

Without additional information linking roses specifically to being red, we cannot deduce that some roses are red based on the given premises. Thus, the logical conclusion “some roses are red” does not necessarily follow and is false.

Can you figure this one out? 🤔

Question: All roses are flowers. Some flowers are red. Therefore, some roses are red. True or False?

Answer: False 🚫

Here’s why: The conclusion “some roses are red” doesn’t logically follow from the premises. While all roses are flowers and some flowers are red, we can’t assume those red flowers include roses without more information.
