Many of the world's largest islands are in the tropics or the arctic. Name those which are (mostly) located between the arctic circle and tropic of cancer OR between the tropic of capricorn and antarctic circle.
Australia is considered a continent here, not an island.
Greenland and Baffin Island are partly in the temperate zone, but most of those islands are north of the arctic circle, so are excluded as arctic islands
Madagascar is crossed by the tropic of capricorn, but most is in thr tropical zone, also excluded.
One answer is nearly bisected by the tropic of cancer but more than half is north of that line, so it is included.
