Social Worker: Typically, the physicians in the United States who promote their services do not charge as much as do physicians who do not promote their services at all. Every time physicians are allowed to promote without restriction, the number of physicians promoting their specialty service has gone up, and patients have paid less for these consultations. Recent changes in regulations of such promotions have lifted the requirement that the amount charged for a consultation appear on the promotion. An effect of this change will be that physicians will no longer be inclined to reduce their fees when they start to promote, and many physicians who promote their services will increase their charges to patients.
In the argument above, the two parts in boldface play which of the following roles?
C. The first supplies an action and a consequence that the social worker perceives will no longer hold true;
the second gives an explanation to support that perception.There is no explanation in the bold part : "many physicians who promote their services will increase their charges to patients." It is just a prediction. it is actually the perception itself, no the support.
An effect of this change will be that physicians will no longer be inclined to reduce their fees when they start to promote, and many physicians who promote their services will increase their charges to patients.
If bold part has been this, C would have been correct.
D. The first provides clarification that the social worker presents in advocacy of a prediction; the second is that prediction.
D seems more correct to me.As it is clarification, and by that it doesn't mean that author is implying if it is right or wrong. Just clarification.
