## Why these answers are right

**28. NO.** The statement claims studies show current drugs can delay aging. Paragraph A says that no treatment on the market today has been proved to slow human aging. That directly contradicts the statement, so the answer is NO.

**29. YES.** The statement says there is scientific evidence that eating fewer calories may extend human life. Paragraph A reports that a low-calorie diet increases longevity in many animals and that these findings suggest it could increase longevity in humans too. The word may matches suggest, so YES.

**30. YES.** The statement says few people will find a caloric-restricted diet attractive. Paragraph B says people would need to cut about thirty percent of their calories and that few mortals could stick to such a harsh regimen for years. That agrees with the statement, so YES.
