Passage Summary: Taking more than a tiny bit of a specific antacid is a bad idea because it can damage your kidneys and might actually cause your stomach to produce more of the very acid you're trying to get rid of.

Reasoning: Calcium carbonate can neutralize stomach acid, but it also increases blood calcium (harming kidneys) and triggers a hormone that causes more acid to be secreted.

Analysis: Since this is a 'Most Strongly Supported' question, we must treat the statements as facts and see what they imply when combined. We have a classic 'rebound effect' scenario: the substance solves a problem (neutralizes acid) but simultaneously triggers a process that worsens that same problem (stimulates gastrin/acid secretion). An ideal answer will likely point out this counterproductive nature or suggest that the health risks to the kidneys make the antacid a double-edged sword. Avoid any answer choices that make broad, sweeping claims not strictly supported by these specific biological interactions.
