All the trees in the park are flowering trees.

So, a flowering tree should satisfy two conditions.

1. It should be a Tree (Some of the trees in the park are dogwoods).
2. It should be in the Park (Some of the trees in the park are dogwoods).

Since, dogwoods satisfy the above conditions, "All dogwoods in the park are flowering trees" - True.

Note: If the dogwoods outside the park, it may or may-not be flowering trees.

If you use the venn diagram, the result is invalid. Also, when you follow the three rules of syllogism you will see that the conclusion is invalid. If we look at the conclusion, the subject (Dogwoods) is not distributed in any of the premises which violates rule #3 of the rules of syllogism.

Yeah! The answer should be false as it is mentioned in the second statement that some trees in the park are dogwood.

And according to my knowledge, we are not supposed to apply our prior knowledge even if dogwood trees are flowering trees.

Correct me if I'm wrong.

This question is totally based on 1st Sentence that.

All the trees in the park are flowering trees.

And the 2nd sentence is Dogwoods which also in the park I mean it is also counted in the All trees in the park I think you got my point.

The 3rd premise doesn't logically follow from the first two premises, in syllogism, if one of the premises is universal (with a quantifier All) and the other is particular (Some) the conclusion should be particular hence wrongly deducted.

If we use the venn diagram the result is invalid. And also according to rules of syllogism the conclusion is invalid because in syllogism, if one of the premises of a statement is particular the conclusion should be particular.

1. all the trees in park is flowering tree
so dogwoods is one kind of tree which is planted in the park
you can say like a classification of tree
so, any kind of tree planted in park is flowering tree

Here is written that all the trees in the plant contain flowers right?

Here it is written all so every plant contains a flower so the dogwood tree also contains flowers.

Correct me if I am wrong.

The correct answer is false. Because some of the trees in park are dogwood not all. So when we do it using venn diagram it will be wrong. So the correct answer is FALSE.
