<human>: Q: What type of aircraft carriers did these ship conversions give rise to in 1927?
 A: As a result of the Washington Naval Treaty of 1922, which limited the construction of new heavy surface combat ships, most early aircraft carriers were conversions of ships that were laid down (or had served) as different ship types: cargo ships, cruisers, battlecruisers, or battleships.
