NO

Problem 1: 

(VAR N X XS)
(RULES
2nd(cons(X)) -> head(XS)
from(X) -> cons(X)
head(cons(X)) -> X
sel(0,cons(X)) -> X
sel(s(N),cons(X)) -> sel(N,XS)
take(0,XS) -> nil
take(s(N),cons(X)) -> cons(X)
)

Problem 1: 

Extra Variables Processor:
-> Rules:
 2nd(cons(X)) -> head(XS)
 from(X) -> cons(X)
 head(cons(X)) -> X
 sel(0,cons(X)) -> X
 sel(s(N),cons(X)) -> sel(N,XS)
 take(0,XS) -> nil
 take(s(N),cons(X)) -> cons(X)
-> The system has extra variables.

The problem is infinite.
