Question
This question is evaluating the understanding of a certain property in set theory or linear algebra. **Question:** (8). If \( L_1 \) and \( L_2 \) are in \( D \), then \( L_1 - L_2 \) must be in \( D \). - ○ True - ○ False **Explanation:** This question asks whether the subtraction of two elements belonging to a set \( D \), specifically \( L_1 - L_2 \), also belongs to that set \( D \). The answer involves understanding the closure properties of set \( D \) with respect to the operation being performed.
