Model Answers

Band 6.0 Answer

Scoring Breakdown

• Task Response (TR): 5.0 - Addresses the task but with some irrelevant points
• Coherence and Cohesion (CC): 6.0 - Presents information with some organization but lacks clear progression
• Lexical Resource (LR): 6.0 - Uses a mix of appropriate and inaccurate vocabulary
• Grammatical Range and Accuracy (GRA): 6.0 - Attempts complex sentences but with frequent errors

Answer

Space exploration is very important for our future, but it has some bad effects. One big problem is the space junk that is floating around Earth. This junk can hit satellites and make them not work. Also, it can be dangerous for astronauts. To solve this problem, we should make rules for countries to clean up their space junk. They can use special robots to catch the junk and bring it back to Earth. This way, space will be safer for everyone.

Another problem is the cost of space exploration. It is very expensive, and some people think we should spend the money on other things like education or health care. To fix this, governments can work together to share the costs. They can also find new ways to make space travel cheaper, like using better technology. This will help us explore space without spending too much money.

In conclusion, space exploration has some problems, but we can solve them if we work together and use our brains.

Band 7.0 Answer

Scoring Breakdown

• Task Response (TR): 7.0 - Addresses all parts of the task with relevant, extended ideas
• Coherence and Cohesion (CC): 7.0 - Presents information with clear progression and logical sequencing
• Lexical Resource (LR): 7.0 - Uses a sufficient range of vocabulary with some less common lexis
• Grammatical Range and Accuracy (GRA): 7.0 - Uses a mix of simple and complex sentence forms with some errors

Answer

Space exploration has brought many benefits to humanity, but it also presents significant challenges. One major problem is the environmental impact on Earth. The launch of rockets releases large amounts of carbon dioxide and other pollutants into the atmosphere, contributing to global warming. Additionally, the debris from space missions can pollute the environment and pose risks to other satellites and spacecraft.

To mitigate this issue, governments and space agencies should invest in developing more environmentally friendly propulsion systems. For instance, electric and solar-powered rockets could significantly reduce the carbon footprint of space missions. Furthermore, international cooperation is essential to establish regulations for the responsible disposal of space debris. By working together, countries can ensure that space exploration does not come at the expense of our planet's health.

In conclusion, while space exploration offers immense potential for scientific discovery and technological advancement, it is crucial to address its environmental impacts. By adopting sustainable practices and fostering international collaboration, we can ensure that space exploration benefits both humanity and the planet.

Band 8.0 Answer

Scoring Breakdown

• Task Response (TR): 8.0 - Addresses all parts of the task with fully extended and supported ideas
• Coherence and Cohesion (CC): 8.0 - Presents information with clear progression and logical sequencing
• Lexical Resource (LR): 8.0 - Uses a sufficient range of vocabulary with some less common lexis
• Grammatical Range and Accuracy (GRA): 8.0 - Uses a mix of simple and complex sentence forms with some errors

Answer

The quest for space exploration has undeniably enriched our understanding of the universe, but it is not without its drawbacks. One pressing issue is the proliferation of space debris, which poses a substantial threat to both operational spacecraft and future missions. This debris, comprising defunct satellites, spent rocket stages, and other fragments, orbits the Earth at high velocities, creating a hazardous environment.

To tackle this problem, a multi-faceted approach is necessary. Firstly, international space agencies should collaborate to develop and implement more robust tracking and monitoring systems. Advanced technologies, such as ground-based radar and space-based telescopes, can provide real-time data on the location and trajectory of space debris. Secondly, innovative solutions for debris removal should be explored. Concepts like laser ablation, electrostatic traps, and robotic arms have shown promise in capturing and de-orbiting debris. By investing in these technologies, we can mitigate the risks associated with space debris and ensure the sustainability of space exploration.

In conclusion, while space exploration presents challenges, proactive measures can be taken to address them. Through international cooperation and technological innovation, we can navigate the complexities of space debris and continue to reap the benefits of exploring the final frontier.

Band 9.0 Answer

Scoring Breakdown

• Task Response (TR): 9.0 - Addresses all parts of the task with fully extended and supported ideas
• Coherence and Cohesion (CC): 9.0 - Presents information with clear progression and logical sequencing
• Lexical Resource (LR): 9.0 - Uses a wide range of vocabulary with precise and sophisticated lexis
• Grammatical Range and Accuracy (GRA): 9.0 - Uses a wide range of complex sentence forms with minimal errors

Answer

The pursuit of space exploration has undeniably expanded the horizons of human knowledge, but it is not devoid of significant challenges. One of the most pressing issues is the escalating problem of space debris, which not only jeopardizes operational spacecraft but also hampers future missions. This debris, comprising a myriad of defunct satellites, spent rocket stages, and other fragments, orbits the Earth at velocities exceeding 17,500 miles per hour, creating a treacherous environment.

To ameliorate this predicament, a concerted effort involving international collaboration and technological innovation is imperative. Firstly, space-faring nations must unite to establish a comprehensive framework for tracking and monitoring space debris. Advanced systems, such as the Space Surveillance Network operated by the United States, can provide real-time data on the location and trajectory of debris. Additionally, the development of active debris removal technologies is crucial. Concepts like the European Space Agency's e.Deorbit mission, which aims to capture and de-orbit large pieces of debris, exemplify the innovative solutions required to address this issue.

Furthermore, the implementation of international regulations and guidelines is essential to prevent the further proliferation of space debris. The United Nations Office for Outer Space Affairs (UNOOSA) plays a pivotal role in promoting the peaceful use of outer space and can facilitate the adoption of such measures. By fostering a culture of responsibility and sustainability, we can ensure that space exploration continues to benefit humanity without compromising the safety of our orbital environment.

In conclusion, while space exploration presents formidable challenges, proactive and collaborative efforts can effectively mitigate its drawbacks. Through international cooperation, technological advancement, and regulatory frameworks, we can navigate the complexities of space debris and continue to explore the cosmos responsibly and sustainably.
