ROUND 1
Japan — 3,000 km
Answer: Japan measures 3,000 km (height), which is 1.1× as big as the reference, Greenland at 2,670 km.
Japan’s island arc extends around 3,000 kilometres.
Common miss: players tend to compress Japan when it sits beside Greenland — big things get squeezed, small familiar things get stretched.
Answer: Australia measures 4,000 km (length / span), which is about 1.1× smaller than the reference, the contiguous United States at 4,500 km.
Australia is nearly as wide as the contiguous United States, with a tenth of the population.
Common miss: players tend to inflate Australia when it sits beside the contiguous United States — big things get squeezed, small familiar things get stretched.
Answer: Hawaiʻi Island measures 150 km (length / span), which is about 6.7× smaller than the reference, metropolitan France at 1,000 km.
The Big Island is larger than all the other Hawaiian islands combined, and still growing.
Common miss: players tend to inflate Hawaiʻi Island when it sits beside metropolitan France — big things get squeezed, small familiar things get stretched.
