1. The problem is to choose the best topic sentence to introduce a paragraph containing details about Vantablack's properties and applications. 2. The details mention Vantablack's composition (densely packed nanotubes that capture light), its use in preventing light interference in satellite imaging, and coating telescope components to reduce light pollution. 3. The best topic sentence should broadly introduce Vantablack's unique property and its applications related to light absorption. 4. Among the options: - "In 2022, the artist Anish Kapoor exhibited several sculptures created using Vantablack." focuses on art, not the technical details. - "Vantablack is a unique coating that has a range of applications due to its ability to absorb light." correctly introduces the coating and its light-absorbing property, matching the details. - "Vantablack has proven to be effective at improving the quality of images collected by satellites." is too narrow, focusing only on satellite imaging. 5. Therefore, the best topic sentence is: **Vantablack is a unique coating that has a range of applications due to its ability to absorb light.**
