The writer is considering adding the following sentence after sentence 11. Focus groups are best understood as sources of potentially valuable information, not as the final word on consumer response.
Should the writer add this sentence?
A
Yes, because it introduces a counterargument to the claim made in sentence 11 that is rebutted in the rest of the paragraph.
B
Yes, because it provides commentary that connects the claim in sentence 11 with the evidence about focus groups provided in sentence 12.
с
No, because it interrupts the discussion of how focus groups provide information with unnecessary details about consumer response.
D
No, because it makes the argument of the passage less convincing by insisting that there is only one way to view focus groups.
E
No, because it includes a vague reference to valuable information without explaining the nature of this information.
