Q: Passage: Manitoba ( (listen)) is a province at the longitudinal centre of Canada. It is often considered one of the three prairie provinces (with Alberta and Saskatchewan) and is Canada's fifth-most populous province with its estimated 1.3 million people. Manitoba covers 649,950 square kilometres (250,900 sq mi) with a widely varied landscape, stretching from the northern oceanic coastline to the southern border with the United States. The province is bordered by the provinces of Ontario to the east and Saskatchewan to the west, the territories of Nunavut to the north, and Northwest Territories to the northwest, and the U.S. states of North Dakota and Minnesota to the south.
Aboriginal peoples have inhabited what is now Manitoba for thousands of years. In the late 17th century, fur traders arrived on two major river systems, what is now called the Nelson in northern Manitoba and in the southeast along the Winnipeg River system. A Royal Charter in 1670 granted all the lands draining into Hudson's Bay to the British company and they administered trade in what was then called Rupert's Land. During the next 200 years, communities continued to grow and evolve, with a significant settlement of Michif in what is now Winnipeg. The assertion of Métis identity and self-rule culminated in negotiations for the creation of the province of Manitoba. There are many factors that led to an armed uprising of the Métis people against the Government of Canada, a conflict known as the Red River Rebellion. The resolution of the assertion of the right to representation led to the Parliament of Canada passing the Manitoba Act in 1870 that created the province.
Manitoba's capital and largest city, Winnipeg, is the eighth-largest census metropolitan area in Canada. Other census agglomerations in the province are Brandon, Steinbach, Portage la Prairie, and Thompson. 
Question: What are the names of the three prairie provinces?

A: Manitoba.

Q: Passage: Sissinghurst Castle Garden, at Sissinghurst in the Weald of Kent in England, was created by Vita Sackville-West, poet and writer, and her husband Harold Nicolson, author and diplomat. It is among the most famous gardens in England and is designated Grade I on Historic England's register of historic parks and gardens. It was bought by Sackville-West in 1930, and over the next thirty years, working with, and later succeeded by, a series of notable head gardeners, she and Nicolson transformed a farmstead of "squalor and slovenly disorder" into one of the world's most influential gardens. Following Sackville-West's death in 1962, the estate was donated to the National Trust for Places of Historic Interest or Natural Beauty. It is one of the Trust's most popular properties, with nearly 200,000 visitors in 2017.
The gardens contain an internationally respected plant collection, particularly the assemblage of old garden roses. The writer Anne Scott-James considered the roses at Sissinghurst to be "one of the finest collections in the world". A number of plants propagated in the gardens bear names related to people connected with Sissinghurst or the name of the garden itself. The garden design is based on axial walks that open onto enclosed gardens, termed "garden rooms", one of the earliest examples of this gardening style. Among the individual "garden rooms", the White Garden has been particularly influential, with the horticulturalist Tony Lord describing it as "the most ambitious ... of its time, the most entrancing of its type."The site of Sissinghurst is ancient and has been occupied since at least the Middle Ages. The present-day buildings began as a house built in the 1530s by Sir John Baker. In 1554 Sir John's daughter Cecily married Thomas Sackville, 1st Earl of Dorset, an ancestor of Vita Sackville-West. By the 18th century the Baker's fortunes had waned, and the house, renamed Sissinghurst Castle, was leased to the government to act as a prisoner-of-war camp during the Seven Years' War. The prisoners caused great damage and by the 19th century much of Sir Richard's house had been demolished. In the mid-19th century, the remaining buildings were in use as a workhouse, and by the 20th century Sissinghurst had declined to the status of a farmstead. In 1928 the castle was advertised for sale but remained unsold for two years. 
Question: What are the enclosed gardens in the Sissinghurst Castle Garden called?

A: garden rooms.

Q: Passage: Palmyra (; Palmyrene:  Tadmor; Arabic: تَدْمُر‎ Tadmur) is an ancient Semitic city in present-day Homs Governorate, Syria. Archaeological finds date back to the Neolithic period, and documents first mention the city in the early second millennium BC. Palmyra changed hands on a number of occasions between different empires before becoming a subject of the Roman Empire in the first century AD.
The city grew wealthy from trade caravans; the Palmyrenes became renowned as merchants who established colonies along the Silk Road and operated throughout the Roman Empire. Palmyra's wealth enabled the construction of monumental projects, such as the Great Colonnade, the Temple of Bel, and the distinctive tower tombs. Ethnically, the Palmyrenes combined elements of Amorites, Arameans, and Arabs. The city's social structure was tribal, and its inhabitants spoke Palmyrene (a dialect of Aramaic), while using Greek for commercial and diplomatic purposes. Greco-Roman culture influenced the culture of Palmyra, which produced distinctive art and architecture that combined eastern and western traditions. The city's inhabitants worshiped local Semitic deities, Mesopotamian and Arab gods.
By the third century AD Palmyra had become a prosperous regional center. It reached the apex of its power in the 260s, when the Palmyrene King Odaenathus defeated Persian Emperor Shapur I. The king was succeeded by regent Queen Zenobia, who rebelled against Rome and established the Palmyrene Empire. In 273, Roman emperor Aurelian destroyed the city, which was later restored by Diocletian at a reduced size. The Palmyrenes converted to Christianity during the fourth century and to Islam in the centuries following the conquest by the 7th-century Rashidun Caliphate, after which the Palmyrene and Greek languages were replaced by Arabic.
Before AD 273, Palmyra enjoyed autonomy and was attached to the Roman province of Syria, having its political organization influenced by the Greek city-state model during the first two centuries AD. The city became a Roman colonia during the third century, leading to the incorporation of Roman governing institutions, before becoming a monarchy in 260. Following its destruction in 273, Palmyra became a minor center under the Byzantines and later empires. Its destruction by the Timurids in 1400 reduced it to a small village. Under French Mandatory rule in 1932, the inhabitants were moved into the new village of Tadmur, and the ancient site became available for excavations. During the Syrian Civil War in 2015, the Islamic State of Iraq and the Levant (ISIL) destroyed large parts of the ancient city, which was recaptured by the Syrian Army on 2 March 2017. 
Question: What is the name of the man that restored the Palmyrene city after it was destroyed by the Roman emperor?

A:
Diocletian.
