Final answer:
Combining the activities of Kellogg and General Mills would violate the economic entity assumption.
Step-by-step explanation:
Combining the activities of Kellogg and General Mills would violate the economic entity assumption.
The economic entity assumption is a fundamental accounting principle which states that the business activities of a company should be kept separate from the personal activities of its owners and other businesses.
By combining the activities of two distinct companies like Kellogg and General Mills, this principle would be violated as it would blur the distinction between the two entities.
