Final answer:
The given sentence lacks parallel structure, as 'those involved with consulting' does not align with the structure of 'vendors' and 'suppliers.' It should be revised to 'The policy affected all vendors, suppliers, and consultants' to create parallelism. Policy operates across diverse realms and can influence multiple sectors.
Step-by-step explanation:
The sentence "The policy affected all vendors, suppliers, and those involved with consulting" does not contain a parallel structure. Parallel structure, also known as parallelism, requires that phrases or clauses in a list or series follow the same grammatical pattern.
To achieve a parallel structure in the given sentence, we might rephrase it to: "The policy affected all vendors, suppliers, and consultants." This revision now aligns the structure of each element in the series (vendors, suppliers, consultants), making them all simple plural nouns.
Understanding how policy occurs and how it impacts a wide range of domains is important. For example, a policy change in the energy sector could impact not only businesses but also schools, governments, and even aspects of environment, tribal sovereignty, and transportation issues. These are key considerations for policy makers as their decisions can have far-reaching effects on various groups and sectors of society.
