Excellent organisation (good use of subheadings and diagrams), well written, impressive factual content (both breadth and depth of information) and mostly relevant. Some evidence of supplementary reading and use of primary literature. Overall an excellent first, perhaps an outstanding answer. –> pick one of the three.
1. What is endosulfan and why have most countries banned its use?
2. Describe the mechanisms of action and toxic effects of organophosphate nerve agents such as sarin. How can poisoning with these agents be treated?
3. Write an essay on the Bhopal tragedy and its aftermath.
