Take the following as truth: Its construction for the 1889 World's Fair was an astounding engineering achievement some 15,000 pieces of metal joined by 2,500,000 rivets, soaring 320 m (984 ft) into the sky on a base only 130 m (430 ft) across.
Then the following statement: "The construction is on the cutting edge of engineering." is true, false, or inconclusive?
