Passage Summary: People go on diets to get healthier and lower their cholesterol. However, when you lose weight, your fat cells shrink and dump their own stored cholesterol into your blood.

Reasoning: Fat cells release stored cholesterol into the bloodstream as they get smaller during weight loss.

Analysis: This is a 'Complete the Argument' task, which functions like a 'Must Be True' question where we must synthesize the facts provided. We know the goal is to lower blood cholesterol, but we also know the physical process of losing weight actually adds cholesterol to the blood. Look for an answer that highlights this ironic or counterintuitive result: that dieting to lower cholesterol might actually cause a temporary spike in it. You are essentially looking for the logical 'punchline' that connects the biological mechanism to the dieter's goal.
