The following text is about biotechnology.
Lab-grown meat, produced by culturing animal cells without raising and slaughtering animals, aims to reduce the environmental impact of meat production. Traditional livestock farming is responsible for substantial greenhouse gas emissions, deforestation, and water use. Early lab-grown products were prohibitively expensive, but costs have fallen dramatically. Challenges remain: scaling production, matching the taste and texture of conventional meat, and gaining regulatory approval and consumer acceptance. Nonetheless, proponents see cultured meat as potentially transformative for global food systems.
What does the text say about the current state of lab-grown meat?
It is already cheaper than conventional meat
Costs have decreased but challenges like scaling and acceptance remain
It has more environmental impact than traditional farming
All regulatory bodies have approved it for sale
Correct Answer: B
Choice B is the correct answer. The text states "costs have fallen dramatically" but notes remaining "challenges" including "scaling production" and "gaining...consumer acceptance."
- Evidence: Cost decreases plus ongoing challenges listed.
- Reasoning: Progress has been made but hurdles remain.
- Conclusion: Improved but not yet fully resolved.
Choice A is incorrect because challenges remain and no comparative cost claim is made. Choice C is incorrect because it aims to "reduce the environmental impact." Choice D is incorrect because "gaining regulatory approval" is listed as a remaining challenge.
