Pedigreed dogs, including those officially classified as working dogs, must conform to standards set by organizations that issue pedigrees.
Conclusion
Pedigree organizations should set standards requiring working ability in pedigreed dogs classified as working dogs.
Evidence
Pedigree standards specify physical appearance only, not other genetic traits. Breeders maintain only traits the standards specify, and unmaintained traits risk being lost.
Intermediate Conclusion
Therefore, certain traits like herding ability risk being lost among pedigreed dogs.
Evaluate
The referenced phrase comes after the premises and before the main conclusion. It is the bridge — supported by the facts about standards and breeder behavior, and used in turn to motivate the recommendation that pedigree organizations should require working ability.
Goal
Identify the answer that calls this phrase a subsidiary (intermediate) conclusion that supports the main conclusion.
