Input: Consider Input: In mid-1961, President Ngo Dinh Diem of South Vietnam asked the United States to conduct aerial herbicide spraying in his country. In August of that year, the Republic of Vietnam Air Force conducted herbicide operations with American help. But Diem's request launched a policy debate in the White House and the State and Defense Departments. However, U.S. officials considered using it, pointing out that the British had already used herbicides and defoliants during the Malayan Emergency in the 1950s. In November 1961, President John F. Kennedy authorized the start of Operation Ranch Hand, the codename for the U.S. Air Force's herbicide program in Vietnam.

Input: Consider Input: Through the Looking-Glass, and What Alice Found There (1872) is a novel by Lewis Carroll (Charles Lutwidge Dodgson), the sequel to Alice's Adventures in Wonderland (1865). Set some six months later than the earlier book, Alice again enters a fantastical world, this time by climbing through a mirror into the world that she can see beyond it. Through the Looking-Glass includes such celebrated verses as 'Jabberwocky' and 'The Walrus and the Carpenter', and the episode involving Tweedledum and Tweedledee. The mirror which inspired Carroll remains displayed in Charlton Kings.

Input: Consider Input: The name Sulis continued to be used after the Roman invasion, leading to the town's Roman name of Aquae Sulis ('the waters of Sulis'). The temple was constructed in 60 -- 70 AD and the bathing complex was gradually built up over the next 300 years. During the Roman occupation of Britain, and possibly on the instructions of Emperor Claudius, engineers drove oak piles to provide a stable foundation into the mud and surrounded the spring with an irregular stone chamber lined with lead. In the 2nd century it was enclosed within a wooden barrel-vaulted building, and included the caldarium (hot bath), tepidarium (lukewarm bath), and frigidarium (cold bath). After the Roman withdrawal from Britain in the first decade of the 5th century, these fell into disrepair and were eventually lost due to silting up, and flooding. The Anglo-Saxon Chronicle suggests the original Roman baths were destroyed in the 6th century.


Output: how old are the roman baths in bath england
