The following text discusses medicine.
The microbiome—the trillions of microorganisms living in our digestive system—influences far more than digestion. Research links gut bacteria to immune function, mental health, and even weight regulation. Some conditions, from autoimmune diseases to depression, show associations with altered microbiomes. Scientists are investigating whether changing the gut microbiome through diet, probiotics, or fecal transplants could treat these conditions. While promising, the field is young, and many claimed benefits remain unproven.
What is the current state of microbiome research according to the text?
All microbiome treatments have been proven effective
Research shows promising connections but many claims remain unproven
Scientists have abandoned microbiome research
The microbiome only affects digestion
Correct Answer: B
Choice B is the correct answer. The text presents associations and ongoing investigation but notes "the field is young, and many claimed benefits remain unproven."
- Evidence: "Promising" but "many claimed benefits remain unproven."
- Reasoning: Early-stage research with potential but incomplete proof.
- Conclusion: Promising findings, uncertain applications.
Choice A is incorrect because many claims "remain unproven." Choice C is incorrect because investigation is ongoing. Choice D is incorrect because immune function, mental health, and weight are also affected.
