NO

Problem 1: 

(VAR X Y Z)
(RULES
first(0,Z) -> nil
first(s(X),cons(Y)) -> cons(Y)
from(X) -> cons(X)
sel(0,cons(X)) -> X
sel(s(X),cons(Y)) -> sel(X,Z)
)

Problem 1: 

Extra Variables Processor:
-> Rules:
 first(0,Z) -> nil
 first(s(X),cons(Y)) -> cons(Y)
 from(X) -> cons(X)
 sel(0,cons(X)) -> X
 sel(s(X),cons(Y)) -> sel(X,Z)
-> The system has extra variables.

The problem is infinite.
