choice by the negasystem (i.e., system fromput).
This concept is complementary to system environment, only viewed from the
"eyes" or perspective of the negasystem.

graduating from high school and looking for a job. An education system
might have used textbooks for sale. An education system might conduct
research an make new knowledge available. These are examples of
negasystem environment.
