Take the following as truth: The evaluators identified the key elements of the programs as implemented and what measurable changes were likely to occur and developed measures of the outcomes, as well as designs for testing cause and effect in the subsequent larger study (Chelimsky and Sasfy, 1976).
Then the following statement: "The evaluators did a lot of hard work in this study, and they were only able to thanks to the full participation of the companies and their representatives." is true, false, or inconclusive?
