1. So the answer here is 1 or true,
2. and you can see that as follows:
3. So X1 is equal to 1, not X2 is equal to 0,
4. so 1 or 0 is equal to 1,
5. so this whole part here is equal to 1,
6. and actually X3 is also equal to 1.
7. So we have that this whole part here is equal to 1,
8. X3 is equal to 1, and 1 or 1 is 1 again,
9. so this whole part here is equal to 1.
10. And over here we have not X1, which is 0 or X2,
11. but X2 is true or 1,
12. and so the whole thing 0 or 1 is equal to 1,
13. and so we have 1 and 1,
14. which evaluates to 1.
