answer:To identify the sum fusion number among the given options, we start by understanding that a sum fusion number is defined as the square difference of two consecutive even numbers. This means we are looking for a number that can be expressed as the difference between the squares of two even numbers that follow each other. Given the options: A: 2020 B: 2021 C: 2022 D: 2023 We first note that the square of an even number is always even, and the difference between the squares of two consecutive even numbers is also even. This immediately tells us that 2021 and 2023, being odd numbers, cannot be sum fusion numbers. Let's denote the two consecutive even numbers as 2k+2 and 2k, where k is an integer. The square difference of these numbers can be represented as: [ (2k+2)^{2}-(2k)^{2} ] Expanding and simplifying this expression, we get: [ = (4k^2 + 8k + 4) - (4k^2) ] [ = 8k + 4 ] [ = 4(2k+1) ] This simplification shows that any sum fusion number can be expressed as 4 times an odd number (since 2k+1 is always odd for any integer k). For 2022, setting 4(2k+1) = 2022 gives us 2k+1 = 505.5. Since 2k+1 must be an integer (as it represents an odd number), k cannot be a half-integer, and thus 2022 cannot be a sum fusion number. For 2020, setting 4(2k+1) = 2020 gives us 2k+1 = 505. This implies k = 252, which is an integer, satisfying the condition for a sum fusion number. Therefore, the correct answer is A: 2020, which can be encapsulated as boxed{A}.

answer:Your essay raises crucial points about the importance of protecting the environment and provides actionable steps for individuals and companies to make a positive impact. Here's a revised version with suggested improvements in grammar, structure, and persuasive power: The problem of protecting the environment has never been more pressing. Despite growing awareness of the impact human activities have on the earth, many individuals still fail to take action to reduce their carbon footprint and help the planet. One major contributor to environmental degradation is the way people live their daily lives. Not recycling, relying on single-occupancy vehicles, and neglecting to use eco-friendly alternatives are all detrimental habits. However, making small changes can add up to make a significant difference. For instance, individuals can start by using reusable bags for grocery shopping, buying in bulk, composting, and choosing products with minimal packaging. Further adjustments can be made by incorporating eco-friendly cleaning products, planting trees, and investing in energy-efficient appliances for the home. Companies also have a crucial role to play and can transition to renewable energy sources like solar panels, reduce waste, and adopt sustainable practices. By implementing these changes, individuals and companies not only contribute to a healthier planet but also reap financial benefits. Buying in bulk and reducing energy consumption, for example, can lead to substantial cost savings. Moreover, taking action to protect the environment can bring a sense of satisfaction and fulfillment, knowing that we are working towards a better future for generations to come. In conclusion, safeguarding the planet is a collective responsibility that requires cooperation between individuals and companies. It is essential that we work together to reduce waste, lower our carbon footprint, and mitigate the harm inflicted on our planet. Some specific suggestions to enhance the essay's impact and persuasiveness include: - Emphasize the urgency and consequences of inaction by adding statistics or real-world examples that illustrate the devastating effects of environmental neglect. - Use more descriptive language to paint a vivid picture of the benefits of environmental stewardship, such as thriving ecosystems or a healthier planet for future generations. - Consider adding a personal anecdote or a success story of a company or community that has made significant environmental strides to inspire and motivate readers. - Use a stronger call-to-action in the conclusion, such as Let us join forces to create a more sustainable future or It is time for us to take responsibility for our planet's well-being.
