Pedigreed dogs, including those officially classified as working dogs, must conform to standards set by organizations that issue pedigrees. Those generally specify the physical appearance necessary for a dog to be recognized as belonging to a breed but stipulate nothing about other genetic traits, such as those that enable breeds originally developed as working dogs to perform the work for which they were developed. Since dog breeders try to maintain only those traits specified by pedigree organizations, and traits that breeders do not try to maintain risk being lost, certain traits like herding ability risk being lost among pedigreed dogs. Therefore, pedigree organizations should set standards requiring working ability in pedigreed dogs classified as working dogs.

Which one of the following principles, if valid, justifies the argument's conclusion that pedigree organizations should set standards for working abilities in dogs?

A. Organizations that set standards for products or activities should not set standards calling for a particular characteristic if such standards increase the risk of some other characteristic being lost.

B. Any standard currently in effect for a product or an activity should be rigorously enforced regardless of when the standard was first set.

C. Organizations that set standards for products or activities should be responsible for seeing to it that those products or activities conform to all the specifications called for by those standards.

E. Organizations that set standards for products or activities should attempt to ensure that those products or activities can sever the purposes for which they were originally developed.

结论：
Pedigreed dogs, including those officially classified as working dogs, must conform to standards set by organizations that issue pedigrees.
----------------------------------------
Why “conform to standards”？
因为 standards 有用，因为这个 standards 可以“ those that enable breeds originally developed as working dogs to perform the work for which they were developed”保留。
即，把“开始想发展”（originally developed）的特性保留。
-----------------------------------------------
即，E
Organizations that set standards for products or activities should attempt to ensure that those products or activities can sever the purposes for which they were originally developed.
