I want to know the answer to the following question:
What organization discovered that the advertisements Beyoncé did for the soft drink company were 70% positive?
All the background I'm provided with is that "The Center for Science in the Public Interest (CSPINET) wrote Beyoncé an open letter asking her to reconsider the deal because of the unhealthiness of the product and to donate the proceeds to a medical organisation.". Is that enough to answer the question?
Answer: no
