Question

The correct answer is B because the author emphasizes that stem-cell therapies aim not merely to prolong life but to restore function and quality of life as well.

1. Relevant knowledge points and concepts
- Reading-for-inference: determine what the author most likely believes based on general claims and tone rather than explicit facts.
- Stem-cell biology (as used in popular summaries): stem cells can regenerate damaged tissues and restore organ function, so benefits are often framed as both life-extending and life-improving.
- Distinguishing supported vs. unsupported claims: plausible general conclusions versus specific, technical claims require explicit passage support.

2. Step-by-step reasoning
- Identify the author’s main claim: the passage stresses therapeutic promise of stem cells in repairing damage and improving patient outcomes. That implies benefits beyond mere survival.
- Compare each option to that main claim:
  a) “Most useful for builders” is irrelevant and flippant; nothing in a serious passage about medical treatments would support that. So A is unsupported.
  b) “Lives that are extended by stem cell treatments will also be improved” matches the idea that restoring tissues improves patients’ functioning and well-being as well as lifespan. This is a general, supported inference.
  c) “Stem cells can use restored brain cells to repair heart tissue” is biologically confused and very specific; the passage would need explicit evidence to make such a cross-tissue mechanism claim. Unlikely and not supported.
  d) “Stem cell treatments are reducing transplant waiting lists” is a factual claim about current health system impact; most discussions present stem cell therapy as promising but experimental, so there’s unlikely to be firm evidence that waiting lists are being reduced now.

3. Why B is correct
- B is a measured, general inference consistent with an author arguing stem-cell therapies repair damaged tissues and thereby improve patients’ lives as well as prolong them. It neither overstates mechanisms nor asserts an unsupported healthcare-system effect.

Conclusion: therefore option B is the best choice, matching the provided answer.
