Explanation

Reasoning:  

1. A is brother of B → A and B are siblings  

2. B is sister of C → B and C are siblings  

So A, B, C are all siblings.

3. C is mother of D → C is D’s mom

Since A is the brother of D’s mom C, A is D’s maternal uncle.

Explanation

Premises:  

1. All engineers are intelligent → Engineers are a small circle inside the bigger "Intelligent" circle  

2. Some intelligent people are not doctors → There’s a part of "Intelligent" that’s outside "Doctors"

Conclusion I: Some engineers are not doctors  

Not necessarily. The "intelligent people who are not doctors" could all be artists, teachers, etc. Engineers might still all be doctors. So I doesn’t follow.

Conclusion II: All doctors are intelligent 

No info given about doctors. Some intelligent people aren’t doctors, but that says nothing about doctors being intelligent or not. So II doesn’t follow.

So from your options: Neither follows

"All roses are flowers" → Every rose is inside the "flowers" circle. So some flowers = roses is definitely true.

"Some flowers fade quickly" → Only tells us about _some_ flowers, not all. We don’t know if those fading flowers are roses or not.

So: "Some flowers are roses" → Must be true, because all roses are flowers.
