Logical Inferences:
I. All mammals build houses:
This cannot be inferred from the given facts. While it is true that humans are mammals and some humans are engineers who build houses, it does not mean that all mammals build houses. There are many mammals that do not build houses, such as lions, tigers, and bears.
II. Engineers are mammals:
This can be inferred from the given facts. Fact 1 states that humans are mammals, and fact 2 states that some humans are engineers. Therefore, it can be concluded that engineers are mammals.
III. Some humans are not engineers:
This can be inferred from the given facts. Fact 2 states that some humans are engineers, which implies that there are humans who are not engineers. Therefore, it can be concluded that some humans are not engineers.
Conclusion:
Based on the given facts, it can be inferred that:
- Engineers are mammals (Fact 2 supports this inference).
- Some humans are not engineers (Fact 2 supports this inference).
Therefore, the correct answer is option 'B'.
