A student has researched bariatric surgery and its effect on type 2 diabetes and compiled the following notes:
- Gastric bypass and sleeve gastrectomy are two common bariatric surgery procedures that produce substantial weight loss.
- Many patients with type 2 diabetes experience major improvement in blood sugar control after these surgeries.
- Blood sugar levels can improve within days after surgery, before most of the weight loss has actually occurred.
- Changes in gut hormones and how nutrients are processed appear to contribute to these metabolic effects.
- Diabetes can sometimes return in patients years after an initially successful surgery.
- The surgeries carry risks during and after the operation, including nutritional complications.
The student wants to challenge the assumption that bariatric surgery improves diabetes symptoms solely by causing weight loss. Which choice most effectively uses relevant information from the notes to accomplish this goal?

Answer and explanation
Answer: D: Blood sugar levels can improve within days after surgery, before most of the weight loss has actually occurred, suggesting that changes in gut hormones and nutrient processing contribute…
Challenging a weight-loss-only explanation requires evidence that something else is at work, and D supplies exactly that: blood sugar improving before substantial weight loss even happens, pointing to an independent mechanism. A simply states the surgeries cause weight loss, reinforcing instead of challenging the assumption. C and B each name a real but separate consideration, risk and recurrence, that doesn't address the mechanism question at all.
