1. **State the problem:** We are given a function $C$ with parameters and sets defined as: $$Qe\ Ue = C \times : x \text{ is an integer}$$ $$C(e, f, g, h, p, q, r, s)$$ and two subsets: $$M = C(e, h, q, s)$$ $$N = C(h, p, r)$$ We need to find the sets $M$ and $N$ based on the given parameters. 2. **Understand the notation:** The function $C$ takes a list of parameters. The sets $M$ and $N$ are defined as subsets of $C$ with specific parameters. 3. **Find $M$:** $M$ is the set $C$ with parameters $(e, h, q, s)$. 4. **Find $N$:** $N$ is the set $C$ with parameters $(h, p, r)$. 5. **Conclusion:** Without additional information about the function $C$, the best we can do is express $M$ and $N$ as the subsets of $C$ with the specified parameters: $$M = C(e, h, q, s)$$ $$N = C(h, p, r)$$ These represent the sets defined by the function $C$ with the given arguments. **Final answer:** $M = C(e, h, q, s)$ $N = C(h, p, r)$
