Science and Environment 2026

Ten questions on 2026's environment and science stories: wetlands, climate conferences, waste rules, a penguin on the Red List, astronauts round the Moon, a failed rocket and India's first chips.

What this topic actually tests

Environment questions pair a 2026 event with a convention or law (Ramsar 1971, the UNFCCC, the Environment (Protection) Act); science questions pair a mission with its record or first. Learn both halves. The stories behind these questions, with their sources, are in the 30-day course: days 24 and 26.

The common trap on this topic

Mixing up places and firsts: India's 99th and 100th Ramsar sites are both in Uttar Pradesh, Artemis II flew round the Moon without landing, and Micron's Sanand plant packages chips rather than making wafers.
