| Statement | Answer | Explanation | |-----------|--------|--------------| | 1. Single-atom catalysts were first created using platinum nanoparticles. | False | Paragraph B says SACs use isolated atoms, not nanoparticles. The first demonstration used platinum atoms, not nanoparticles. | | 2. Mechanochemistry has been universally accepted as reproducible. | False | Paragraph C states critics argue it lacks reproducibility; a 2019 study only partially settled the debate. Not universally accepted. | | 3. Artificial photosynthesis devices currently operate at over 10% efficiency. | False | Paragraph D: “efficiencies remain below 5%.” So 10% is false. | | 4. Machine learning models can perfectly predict stereochemistry. | False | Paragraph E: “it struggles with stereochemistry and novel substrates” – so not perfect. | | 5. The public has always viewed chemistry with enthusiasm. | Not Given | Paragraph F mentions public perception “tainted by pollution” but does not say “always.” No historical data given. |
