Sample Reading Passage: Ethical Implications of Genetic Modification in Agriculture
Background
Genetic modification, or genetic engineering, involves altering the genetic makeup of organisms. In agriculture, this technology has been used to improve crop yields, resistance to pests, and adaptability to environmental conditions. However, it has also raised significant ethical concerns regarding health, environment, and socioeconomic impacts.
Sample Passage
Genetically modified (GM) crops have been a topic of intense debate. Proponents argue that GM crops can address food security concerns by increasing yields and providing essential nutrients. For instance, GM rice enriched with Vitamin A – known as Golden Rice – aims to combat malnutrition in developing countries. Nevertheless, critics raise ethical issues, questioning the long-term health impacts of consuming GM foods. Studies show conflicting results, with some asserting no significant health risks, while others suggest potential for allergens and unforeseen consequences.
Environmental implications also pose ethical dilemmas. GM crops are designed to be pest-resistant, reducing the need for chemical pesticides. However, there’s evidence suggesting that pests can develop resistance over time, necessitating even stronger chemicals. Furthermore, the cross-contamination of GM and non-GM crops can disrupt biodiversity. Ecosystems rely on varied species for stability, and the dominance of GM crops may lead to the extinction of native species.
From a socioeconomic perspective, the ethical concerns are multifaceted. Large biotechnology companies often hold patents on GM seeds, compelling farmers to purchase new seeds every planting season. This corporate control can marginalize small-scale farmers, leading to economic disparities. Additionally, ethical questions about consumer rights arise. Should people have the right to know whether their food is genetically modified? Some argue that labeling GM foods is crucial for informed consumer choices, while others contend that it could lead to unnecessary fear and rejection of safe food products.

- One ethical question about GM foods is whether consumers __.
Answer Key and Detailed Explanations
- (b) Increased crop yields: The primary argument for GM crops is their potential to increase yields and thus address food security concerns.
- (c) Malnutrition: Golden Rice is specifically developed to combat vitamin A deficiency-related malnutrition.
- (b) Pests may develop resistance to GM crops: This is a key environmental concern as it necessitates stronger chemicals over time.
- False: There are conflicting studies, but no definitive proof of health problems.
- True: Cross-contamination can affect biodiversity.
- Not Given: The passage discusses economic impacts but does not provide a consensus view of all small-scale farmers.
- increased dependency on biotechnological companies: Small farmers may struggle with the cost of purchasing new patented seeds each season.
- should have the right to know about genetic modifications in their food: The passage questions if consumers should be informed about the GM status of their food products.
