Below are the statements followed by two conclusions numbered I and II...
Statements:
- a. Some roses are thorns.
- b. All thorns are flowers.
- c. No flower is a petal.
Conclusions:
- I. No petal is a rose.
- II. Some flowers are roses.
Explanation:
Both conclusions I and II can be logically derived from the given statements.
Conclusion I:
- From statement a, we know that some roses are thorns.
- From statement b, we know that all thorns are flowers.
- Combining these two statements, we can conclude that no petal is a rose. Therefore, conclusion I follows.
Conclusion II:
- From statement b, we know that all thorns are flowers.
- Since some roses are thorns (from statement a), it follows that some flowers are roses. Therefore, conclusion II also follows.
Therefore, the correct answer is option B: only conclusion II follows.
