Twelve firms in the Lensdale industrial district moved to a four-day working week at the start of last year. Every one of the twelve has since reported higher output per employee than it recorded in the year before the change. A consultant advising the district's business association concludes that any firm in the district would raise its output per employee by moving to a four-day week.

The consultant's reasoning is most vulnerable to criticism on which of the following grounds?

AIt does not establish that the twelve firms' gains in output per employee were of similar size.

BIt draws a conclusion about the productivity of individual employees from evidence about firms taken as wholes.

CIt treats a result found among firms that chose a change as one the change itself would produce in firms that did not choose it.

DIt assumes that output per employee is the only measure of a firm's performance that its owners have reason to care about.

EIt concludes that a four-day week is necessary if a firm is to raise its output per employee.
