Question: Name the country which adopted the Union jack as the semi-official status?

full_context: Document 1: Flag of Great Britain: The flag of Great Britain, commonly known as the Union Jack or Union Flag, is a maritime flag of Great Britain that was used from 1606 to 1801. The design was ordered by King James VI and I to be used on ships on the high seas, and it subsequently came into use as a national flag following the Treaty of Union and Acts of Union 1707, gaining the status of "the Ensign armorial of the Kingdom of Great Britain", the newly created state. It was later adopted by land forces, although the blue field used on land-based versions more closely resembled that of the blue of the flag of Scotland.
Document 2: Ulster Banner: The Ulster Banner (Ulster-Scots: "Ulstèr Bannèr"; Irish: "Meirge Uladh" ) is a heraldic banner taken from the former coat of arms of Northern Ireland, consisting of a red cross on a white field, upon which is a crowned six-pointed star with a red hand in the centre. It was the flag of the former Government of Northern Ireland and common flag of Northern Ireland from 1953 until that government was abolished in 1972. It was adopted to mark the coronation of Queen Elizabeth II, and was first flown over Parliament Buildings on 1 July 1953, in honour of the Queen's visit. The Minister of Home Affairs announced that, while the Union Jack was the only standard officially recognised, those who wished to have a distinctive Ulster symbol might use the banner. Since 1972, the Ulster Banner has had no official status and is not used by the current Northern Ireland government or by the British government. However, the Ulster Banner is still in common use by loyalists/unionists, and to represent Northern Ireland internationally in some sporting competitions. It has become a symbol of Ulster loyalism and is a contentious symbol. In recent years there have been calls for a new, neutral flag for Northern Ireland to replace the Ulster Banner.
Document 3: Union Jack: The Union Jack, or Union Flag, is the national flag of the United Kingdom. The flag also has an official or semi-official status in some other Commonwealth realms; for example, it is, by parliamentary resolution, a ceremonial flag in Canada and known there as the Royal Union Flag. Further, it is used as an official flag in some of the smaller British overseas territories. The Union Flag also appears in the canton (upper left-hand quarter) of the flags of several nations and territories that are former British possessions or dominions.
Document 4: Union Jack dress: The Union Jack dress was an item of clothing worn by singer Geri Halliwell of the Spice Girls at the 1997 BRIT Awards. The mini dress featured a flag of the United Kingdom, the Union Jack, on the front, and a white peace symbol emblazoned on the black-coloured back of the dress. The next day the images of the dress made the front page of various newspapers around the world, and is now remembered as one of the most iconic pop moments of the 1990s and Brit Awards history. The dress has become synonymous with the Spice Girls, Halliwell and the notions of Girl Power and Cool Britannia.
Document 5: Flag of Northern Ireland: The official flag of Northern Ireland is the Union Flag of the United Kingdom. From 1953 until 1973, the Ulster Banner (also known as the Ulster flag) was used by the Parliament of Northern Ireland; however, since its abolition use of the flag has been limited to representing Northern Ireland in certain sports, at the Commonwealth of Nations, at some local councils and at some other organisations and occasions. Despite this, the Ulster Banner is still commonly seen and referred to as the flag of Northern Ireland, especially by those from the unionist and loyalist communities.
Document 6: Commonwealth realm: A Commonwealth realm is a sovereign state that is a member of the Commonwealth of Nations and shares the same person, currently Elizabeth II, as its head of state and reigning constitutional monarch, but retains a crown legally distinct from the other realms. As of 2017, there are 16 Commonwealth realms: Antigua and Barbuda, Australia, Barbados, Belize, Canada, Grenada, Jamaica, New Zealand, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands, The Bahamas, Tuvalu and the United Kingdom.
Document 7: Royal Arms of Scotland: The royal arms of Scotland was the official coat of arms of the King of Scots first adopted in the 12th century. With the Union of the Crowns in 1603, James VI inherited the thrones of England and Ireland and thus his arms in Scotland were now quartered with the arms of England (which was itself quartered with France) with an additional quarter for Ireland also added (the arms would continue to alter in later years). Though the kingdoms of England and Scotland would share the same monarch, the distinction in heraldry used in both kingdoms was maintained. When the kingdoms of Scotland and England were united under the Acts of Union 1707 to form the United Kingdom of Great Britain, no single arms were created and instead, the royal arms as used in either Scotland and the rest of the United Kingdom would continue to differ.
Document 8: Royal Banner of Scotland: The Royal Banner of the Royal Arms of Scotland, also known as the Royal Banner of Scotland, or more commonly the Lion Rampant of Scotland, and historically as the Royal Standard of Scotland, (Scottish Gaelic: "Bratach rìoghail na h-Alba" , Scots: "Ryal banner o Scotland" ) or Banner of the King of Scots, is the Royal Banner of Scotland, and historically, the Royal Standard of the Kingdom of Scotland. Used historically by the King of Scots, the banner differs from Scotland's national flag, the Saltire, in that its correct use is restricted by an Act of the Parliament of Scotland to only a few Great Officers of State who officially represent the Sovereign in Scotland. It is also used in an official capacity at royal residences in Scotland when the Sovereign is not present.
Document 9: Flag of Niue: The flag of Niue was adopted on 15 October 1975. It consists of the Union Jack in the upper left corner with a star in the middle of the Union Jack and four stars forming a diamond around it. It is very unusual for a flag based on a British ensign design, in having not only a yellow background, but also a defaced Union Jack in the canton.
Document 10: Union Jack (magazine): The Union Jack was a story paper of the late 19th and early 20th centuries. There were two story papers called "Union Jack". The first appeared in the 1880s but was only very short-lived. The name was then used by Alfred Harmsworth in 1894 for a new halfpenny storypaper intended as a companion to the successful "Halfpenny Marvel".
Document 11: Flag of Saint Pierre and Miquelon: The flag of Saint-Pierre and Miquelon is officially the flag of France, as Saint-Pierre and Miquelon is a self-governing overseas collectivity of France.
Document 12: Union Jack (band): Union Jack is a trance music collaboration between Simon Berry and Claudio Giussani, a trance music producer from England. The duo has focused on acid and tech trance and has been closely associated with the Platipus record label, which was founded by Berry.
Document 13: Royal coat of arms of the United Kingdom: The royal coat of arms of the United Kingdom, or the Royal Arms for short, is the official coat of arms of the British monarch, currently Queen Elizabeth II. These arms are used by the Queen in her official capacity as monarch of the United Kingdom. Variants of the Royal Arms are used by other members of the British royal family; and by the British government in connection with the administration and government of the country. In Scotland, there exists a separate version of the Royal Arms, a variant of which is used by the Scotland Office. The arms in banner form serve as basis for the monarch's official flag, known as the "Royal Standard".
Document 14: Flag of Scotland: The Flag of Scotland (Scottish Gaelic: "bratach na h-Alba" ; Scots: "Banner o Scotland" ), also known as St Andrew's Cross or the Saltire, is the Flag of Scotland. As the national flag, the Saltire, rather than the Royal Standard of Scotland, is the correct flag for all individuals and corporate bodies to fly. It is also, where possible, flown from Scottish Government buildings every day from 8am until sunset, with certain exceptions.
Document 15: Flag of the United States: The flag of the United States of America, often referred to as the American flag, is the national flag of the United States. It consists of thirteen equal horizontal stripes of red (top and bottom) alternating with white, with a blue rectangle in the canton (referred to specifically as the "union") bearing fifty small, white, five-pointed stars arranged in nine offset horizontal rows, where rows of six stars (top and bottom) alternate with rows of five stars. The 50 stars on the flag represent the 50 states of the United States of America, and the 13 stripes represent the thirteen British colonies that declared independence from the Kingdom of Great Britain, and became the first states in the U.S. Nicknames for the flag include The Stars and Stripes, Old Glory, and The Star-Spangled Banner.
