ROUND 1
Eiffel Tower — 330 m
Answer: the Eiffel Tower measures 330 m (height), which is about 1.3× smaller than the reference, the Empire State Building at 443.2 m.
The Eiffel Tower reaches about 330 metres including its antenna.
Common miss: players tend to inflate the Eiffel Tower when it sits beside the Empire State Building — big things get squeezed, small familiar things get stretched.
Answer: an Argentinosaurus measures 33 m (length / span), which is 1.5× as big as the reference, a Brachiosaurus at 22 m.
Some estimates place this giant at more than 30 metres long.
Common miss: players tend to compress an Argentinosaurus when it sits beside a Brachiosaurus — big things get squeezed, small familiar things get stretched.
Answer: an adult horse measures 2.4 m (length / span), which is about 1.1× smaller than the reference, a concert grand piano at 2.7 m.
A riding horse is roughly as long as a dairy cow.
Common miss: players tend to inflate an adult horse when it sits beside a concert grand piano — big things get squeezed, small familiar things get stretched.
