By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

SEL2(s1(X), cons2(Y, Z)) -> SEL2(X, activate1(Z))
Used argument filtering: SEL2(x1, x2)  =  x1
s1(x1)  =  s1(x1)
activate1(x1)  =  x1
n__from1(x1)  =  n__from
from1(x1)  =  from
cons2(x1, x2)  =  cons
Used ordering: Quasi Precedence: [n__from, from, cons]
