CR PASSAGE
Environmental conservation has always been a point of debate. One widely discussed approach to mitigate the adverse effects of deforestation is reforestation—planting trees in areas where forests once thrived. While reforestation is hailed as an effective method for combating climate change and enhancing biodiversity, it is not a perfect solution. For one, reforested areas often consist of monoculture plantations rather than diverse ecosystems. Such plantations, though visually similar to forests, lack the ecological complexity required to support a wide variety of species.
Another criticism is that reforestation projects can sometimes result in land-use conflicts. For instance, in developing countries, reforestation initiatives often displace local communities or disrupt agricultural practices. Furthermore, the carbon sequestration potential of young plantations is significantly lower than that of mature forests. It takes decades for reforested areas to reach the carbon absorption levels of naturally grown forests.
On the other hand, proponents argue that reforestation remains a vital tool in addressing the growing carbon emissions problem. Studies suggest that large-scale tree planting campaigns can offset up to 20% of global emissions if executed effectively. Additionally, reforestation contributes to soil stabilization, reducing the risk of floods and erosion. In areas affected by industrial activities, such projects help restore degraded lands.

In recent years, there has been a surge in the popularity of electric vehicles (EVs) as a cleaner alternative to conventional fossil-fuel-powered cars. EVs are lauded for their potential to reduce greenhouse gas emissions and decrease dependence on finite fossil fuel resources. Governments worldwide are providing incentives like tax rebates and subsidies to promote EV adoption. However, critics argue that EVs are not entirely as eco-friendly as they seem.
One major concern is the environmental cost of lithium-ion batteries, which power most EVs. The extraction of lithium and other rare earth metals involves extensive mining, which damages ecosystems and consumes vast amounts of water. Furthermore, the manufacturing process for EVs generates significant emissions, sometimes offsetting the benefits of their zero tailpipe emissions. Additionally, in regions where electricity is primarily generated from coal or natural gas, the environmental impact of EVs is comparable to that of traditional vehicles.
Despite these concerns, proponents emphasize that EV technology is rapidly evolving. Advances in battery recycling and the transition to renewable energy sources can substantially reduce the environmental footprint of EVs. Moreover, widespread EV adoption could spur further investment in sustainable infrastructure, such as charging networks powered by solar or wind energy.
6. Which of the following, if true, most strengthens the argument in favor of EVs as an eco-friendly alternative?
a) Lithium mining practices have become significantly more sustainable.

The increasing use of social media has transformed the way individuals interact and share information. Platforms like Twitter, Facebook, and Instagram have given people unprecedented access to global audiences, enabling them to voice their opinions and advocate for causes. While social media is often credited with fostering a sense of community and collective action, it has also been criticized for promoting misinformation and creating echo chambers.
One of the major criticisms is that social media algorithms are designed to prioritize content that garners high engagement, often amplifying sensational or polarizing posts. This can lead to the rapid spread of misinformation, making it difficult for users to discern credible sources. Moreover, these algorithms reinforce existing beliefs by showing users content aligned with their preferences, thereby creating echo chambers that stifle constructive dialogue.
Proponents, however, argue that social media remains a powerful tool for positive change. Activists have successfully used these platforms to raise awareness about social justice issues and mobilize support for humanitarian efforts. In addition, social media has democratized access to information, giving marginalized communities a platform to amplify their voices.

The debate over genetically modified organisms (GMOs) in agriculture continues to polarize public opinion. Proponents argue that GMOs can help address global food insecurity by increasing crop yields, enhancing nutritional content, and making plants resistant to pests and diseases. For instance, genetically modified rice enriched with vitamin A—commonly known as “Golden Rice”—has been developed to combat vitamin A deficiency in developing countries.
Critics, however, raise concerns about the long-term safety of GMOs. They argue that the introduction of genetically modified crops could lead to unforeseen environmental consequences, such as the emergence of pesticide-resistant pests or the unintentional harm to non-target species. Additionally, opponents highlight the potential economic impact on small-scale farmers, who may struggle to compete with large agribusinesses that dominate the GMO seed market.
Despite these criticisms, there is a growing consensus among scientists that GMOs are safe for consumption. Regulatory agencies worldwide, including the World Health Organization (WHO) and the Food and Agriculture Organization (FAO), have endorsed the use of GMOs after rigorous safety assessments. However, the ethical and economic implications of their widespread adoption remain contentious.
16. Which of the following, if true, most strengthens the argument in favor of GMOs?
a) Studies show that GMOs have consistently improved soil fertility in farming regions.
b) The adoption of GMOs has significantly reduced the use of chemical pesticides worldwide.

d) Consumers are more likely to purchase GMO products if they are labeled clearly.
17. What assumption underlies the criticism regarding the economic impact of GMOs?
a) Farmers prefer traditional farming methods over genetically modified crops.
b) The dominance of large agribusinesses in the GMO market limits opportunities for small-scale farmers.

d) Non-GMO farming methods are capable of producing equally high yields.
The concept of universal basic income (UBI)—a fixed amount of money provided to all citizens regardless of employment status—has gained traction in recent years as a potential solution to poverty and economic inequality. Advocates of UBI argue that it provides financial security, enabling individuals to pursue education, entrepreneurship, or caregiving without the pressure of meeting basic needs. Studies from pilot programs in Finland and Canada suggest that recipients of UBI experience improved mental health and greater job satisfaction.
Opponents, however, argue that UBI is an impractical solution due to its high cost. Funding a universal income program would require substantial increases in taxes or reallocating resources from existing social welfare programs. Critics also contend that providing unconditional income could reduce motivation to work, thereby harming overall productivity. Additionally, there are concerns that UBI does not address structural issues in the labor market, such as lack of access to quality education and healthcare.
Despite these challenges, UBI continues to be explored by policymakers as automation and artificial intelligence threaten to displace millions of jobs. Proponents argue that in an era of technological disruption, UBI could act as a safety net, ensuring economic stability during times of transition.
21. Which of the following, if true, most strengthens the argument in favor of UBI?
a) UBI pilot programs have shown a significant reduction in homelessness rates.
b) Countries with UBI programs have higher tax revenues than those without.

d) Employment rates have declined in regions where UBI has been implemented.
22. What assumption underlies the criticism that UBI reduces motivation to work?
a) Financial security leads individuals to seek alternative income sources.
b) Unconditional income discourages individuals from pursuing employment.
c) The primary goal of social welfare is to incentivize work.
d) UBI programs are only feasible in low-unemployment economies.

a) UBI is a proven solution to poverty and inequality worldwide.
b) The high cost of UBI makes it unlikely to be implemented at a national level.
c) UBI has potential benefits but faces significant economic and structural challenges.
