Question

a) gm crops that resist pests and harsh environments. b) crops with shorter shelf life. c) crops needing more water and pesticides. d) crops that cannot grow without chemicals. 8. what is one medical use of genetic engineering mentioned? a) developing antibiotics. b) creating vaccines. c) gene therapy to correct faulty genes. d) using herbal remedies. 9. what ethical concern is discussed? a) it is always safe and risk - free. b) morality of altering genetic makeup, especially in humans. c) it has no environmental impact. d) everyone agrees it is morally acceptable. 10. what role do regulatory agencies play? a) ban all genetic research. b) ensure safety and responsible conduct in genetic engineering. c) promote unrestricted genetic modification. d) fund only agricultural projects. passage 3: the role of renewable energy in combating climate change renewable energy sources such as solar, wind, hydroelectric, and geothermal power provide sustainable alternatives to fossil fuels, which contribute heavily to climate change. these energy sources rely on natural processes that replenish over time and produce little or no greenhouse gas emissions. switching to renewable energy reduces air pollution and helps lower carbon footprints. however, challenges include higher initial costs, reliance on weather conditions, and the need for modern infrastructure. governments and organizations worldwide are investing in technology and research to make renewable energy more efficient and affordable. adopting renewable energy is essential for creating a cleaner environment and slowing global warming, benefiting current and future generations. questions for passage 3: 11. what is the main idea of the passage? a) fossil fuels are better and cheaper than renewable energy. b) renewable energy provides sustainable alternatives to fossil fuels. c) renewable energy causes more pollution than fossil fuels. d) renewable energy has no impact on climate change.

Explanation:

• Question 8: Genetic engineering in medicine can be used for gene therapy to correct faulty genes. Antibiotics are mainly developed through other microbiological - based methods, creating vaccines is a part of immunology and genetic engineering is not the main way for herbal remedies.
• Question 9: One of the major ethical concerns of genetic engineering is the morality of altering genetic makeup, especially in humans. It is not risk - free, has environmental impacts, and there is no consensus on its moral acceptability.
• Question 10: Regulatory agencies in genetic engineering aim to ensure safety and responsible conduct. They do not ban all research, promote unrestricted modification, or only fund agricultural projects.
• Question 11: The passage emphasizes that renewable energy provides sustainable alternatives to fossil fuels, reduces air pollution, and helps combat climate change despite some challenges.

Answer:

1. C. Gene therapy to correct faulty genes
2. B. Morality of altering genetic makeup, especially in humans
3. B. Ensure safety and responsible conduct in genetic engineering
4. B. Renewable energy provides sustainable alternatives to fossil fuels
