The image contains a list of unit assessment questions on logic gates and Boolean algebra. I can break down the questions and provide solutions or guidance. Let me know which question you'd like to start with or if you’d like me to tackle them one by one.

Here are the topics covered in the questions:

1. Creating Boolean expressions and applying De Morgan’s theorem.
2. Truth tables for equivalent circuits.
3. Equivalence of NOR gates based on De Morgan’s theorem.
4. Explanation of universal gates (NAND and NOR).
5. Logic simplification through double inversion.
6. XOR gate truth table and diagram.
7. NOR gate and its equivalent gate using De Morgan’s theorem.
8. Boolean equations for a NOR gate.
9. NAND gate equivalent using De Morgan’s theorem.
10. Boolean equations for NAND gate.
11. Boolean expression circuit design (e.g., $V = WX + YZ$).
12. OR circuit with only NOR gates.
13. AND circuit using only NAND gates. 14-15. Truth table analysis to compare outputs of specific gates.

Let me know which question you'd like to work on first!
