Free LSAT drill for Logical Reasoning (Main Conclusion/Main Point):
1) The expansion of the renewable energy sector has led to a significant decrease in the cost of solar panels. As a result, more households are installing solar panels on their rooftops, which in turn has led to a decrease in overall electricity bills. However, this widespread adoption has also caused a decrease in the profitability of traditional power companies.
Which one of the following most accurately expresses the conclusion of the argument?
A) The renewable energy sector will continue to expand in the coming years.
B) More households are installing solar panels on their rooftops.
C) The profitability of traditional power companies has decreased due to the widespread adoption of solar panels.
D) Renewable energy is becoming more affordable for households.
E) The decrease in electricity bills is a direct result of the expansion of the renewable energy sector.
2) Recent studies have shown that regular exercise not only improves physical health but also has significant mental health benefits. People who exercise regularly report lower levels of stress and anxiety and higher levels of happiness and well-being. Therefore, incorporating regular exercise into one's daily routine is essential for maintaining both physical and mental health.
Which one of the following most accurately expresses the conclusion of the argument?
A) Regular exercise improves both physical and mental health.
B) People who exercise regularly report lower levels of stress and anxiety.
C) Incorporating regular exercise into one's daily routine is essential for maintaining both physical and mental health.
D) Recent studies have shown that exercise has significant mental health benefits.
E) Higher levels of happiness and well-being are associated with regular exercise.
3) Recent studies have shown that the decline in honeybee populations is primarily due to the use of neonicotinoid pesticides. These pesticides weaken bees' immune systems and disrupt their ability to navigate and communicate effectively. Therefore, to reverse the decline in honeybee populations, governments worldwide must ban the use of neonicotinoid pesticides in agriculture.
Which one of the following most accurately expresses the conclusion of the argument?
A) Neonicotinoid pesticides weaken bees' immune systems and disrupt their ability to navigate and communicate.
B) Recent studies have shown a correlation between the use of neonicotinoid pesticides and the decline in honeybee populations.
C) Governments worldwide should take immediate action to ban neonicotinoid pesticides to protect honeybee populations.
D) The decline in honeybee populations poses a significant threat to global agriculture.
E) Effective communication and navigation are crucial for honeybee populations to thrive.
4) In recent years, advancements in artificial intelligence have revolutionized various industries, leading to increased efficiency and automation. While proponents argue that AI will continue to drive economic growth and innovation, critics caution against its unchecked deployment due to potential job displacement and ethical concerns. Therefore, policymakers must navigate the complexities of AI adoption carefully to maximize its benefits while minimizing its negative impacts on society.
Which one of the following most accurately expresses the main point of the argument above?
A) Artificial intelligence has revolutionized industries by enhancing efficiency and automation.
B) Proponents believe that artificial intelligence will drive economic growth and innovation, while critics highlight concerns about job displacement and ethics.
C) Policymakers should carefully consider both the benefits and potential drawbacks of artificial intelligence before implementing widespread adoption.
D) The adoption of artificial intelligence should be regulated to ensure that its benefits are maximized and its negative impacts on society are minimized.
E) The use of artificial intelligence in industries has sparked debates about its economic, social, and ethical implications.
5) Historically, investments in renewable energy sources such as solar and wind power have been promoted as effective strategies to combat climate change and reduce dependency on fossil fuels. While renewable energy technologies have improved in efficiency and affordability, challenges remain in integrating them into existing energy grids and addressing intermittency issues. Therefore, governments and industry leaders must continue to invest in research and infrastructure to overcome these challenges and accelerate the transition to a sustainable energy future.
Which one of the following most accurately expresses the main point of the argument above?
A) Renewable energy sources like solar and wind power are effective strategies to combat climate change and reduce fossil fuel dependency.
B) Investments in renewable energy technologies have improved efficiency and affordability, yet challenges persist in integrating them into existing energy grids.
C) Governments and industry leaders should invest in research and infrastructure to address challenges in integrating renewable energy sources into existing energy grids.
D) The transition to a sustainable energy future requires ongoing investments in research and infrastructure to overcome challenges associated with renewable energy technologies.
E) The adoption of renewable energy sources faces challenges in addressing intermittency issues and integrating them into existing energy grids.
Answers:
1) (C). The conclusion of the argument is that the widespread adoption of solar panels has caused a decrease in the profitability of traditional power companies. The argument supports this conclusion by explaining how the expansion of the renewable energy sector and the decrease in the cost of solar panels led to more households installing solar panels, which then impacted the profitability of traditional power companies.
2) (C). The conclusion of the argument is that incorporating regular exercise into one's daily routine is essential for maintaining both physical and mental health. The argument supports this conclusion by providing evidence from recent studies showing the benefits of regular exercise on physical and mental health.
3) (C). The conclusion of the argument is that governments worldwide should take immediate action to ban neonicotinoid pesticides to protect honeybee populations. The argument supports this conclusion by presenting evidence that links the use of these pesticides to the decline in honeybee populations and the detrimental effects on their health and behavior.
4) (D). The main point of the argument is that policymakers should regulate the adoption of artificial intelligence to ensure that its benefits are maximized while its negative impacts on society, such as job displacement and ethical concerns, are minimized. This conclusion is supported by presenting both the advantages and criticisms of AI and advocating for careful consideration before widespread adoption.
5) (D). The main point of the argument is that governments and industry leaders should continue to invest in research and infrastructure to overcome challenges associated with integrating renewable energy sources into existing energy grids. The argument emphasizes the need for ongoing investments to accelerate the transition to a sustainable energy future despite improvements in renewable energy technologies.
