Q: I have a test where I am given the following article, what is an answer for the question: What was the name of Liang Ji's sister? ? The first group of people claiming to be an ambassadorial mission of Romans to China was recorded as having arrived in 166 AD by the Book of the Later Han. The embassy came to Emperor Huan of Han China from "Andun" (Chinese: ; Emperor Antoninus Pius or Marcus Aurelius Antoninus), "king of Daqin" (Rome). As Antoninus Pius died in 161 AD, leaving the empire to his adoptive son Marcus Aurelius Antoninus, and the envoy arrived in 166 AD, confusion remains about who sent the mission, as both emperors were named "Antoninus". The Roman mission came from the south (therefore probably by sea), entering China by the frontier of Rinan or Tonkin (present-day Vietnam). It brought presents of rhinoceros horns, ivory, and tortoise shell, probably acquired in Southern Asia. The text states that it was the first time there had been direct contact between the two countries. Yule speculated that the Roman visitors must have lost their original wares due to robbery or shipwreck and used the gifts instead, prompting Chinese sources to suspect them of withholding their more precious valuables, which Yule notes was the same criticism directed at papal missionary John of Montecorvino when he arrived in China in the late 13th century AD. Historians Rafe de Crespigny, Peter Fibiger Bang, and Warwick Ball believe that this was most likely a group of Roman merchants rather than official diplomats sent by Marcus Aurelius. Crespigny stresses that the presence of this Roman embassy as well as others from Tianzhu (in northern India) and Buyeo (in Manchuria) provided much-needed prestige for Emperor Huan, as he was facing serious political troubles and fallout for the forced suicide of politician Liang Ji, who had dominated the Han government well after the death of his sister Empress Liang Na. Yule emphasised that the Roman embassy was said to come by way of Jiaozhi in northern Vietnam, the same route that Chinese sources claimed the embassies from Tianzhu (northern India) had used in 159 and 161 AD.
A: Empress Liang Na

Q: I have a test where I am given the following article, what is an answer for the question: What does the modern monitoring system on Mauna Loa consist of? ? Established on Kilauea in 1912, the Hawaiian Volcano Observatory (HVO), presently a branch of the United States Geological Survey, is the primary organization associated with the monitoring, observance, and study of Hawaiian volcanoes. Thomas A. Jaggar, the observatory's founder, attempted a summit expedition to Mauna Loa to observe its 1914 eruption, but was rebuffed by the arduous trek required (see Ascents). After soliciting help from Lorrin A. Thurston, in 1915 he was able to persuade the US Army to construct a "simple route to the summit" for public and scientific use, a project completed in December of that year; the Observatory has maintained a presence on the volcano ever since.Eruptions on Mauna Loa are almost always preceded and accompanied by prolonged episodes of seismic activity, the monitoring of which was the primary and often only warning mechanism in the past and which remains viable today. Seismic stations have been maintained on Hawaii since the Observatory's inception, but these were concentrated primarily on Kilauea, with coverage on Mauna Loa improving only slowly through the 20th century. Following the invention of modern monitoring equipment, the backbone of the present-day monitoring system was installed on the volcano in the 1970s. Mauna Loa's July 1975 eruption was forewarned by more than a year of seismic unrest, with the HVO issuing warnings to the general public from late 1974; the 1984 eruption was similarly preceded by as much as three years of unusually high seismic activity, with volcanologists predicting an eruption within two years in 1983.The modern monitoring system on Mauna Loa is constituted not only by its locally seismic network but also of a large number of GPS stations, tiltmeters, and strainmeters that have been anchored on the volcano to monitor ground deformation due to swelling in Mauna Loa's subterranean magma chamber, which presents a more complete picture of the events proceeding eruptive activity. The GPS network is the most durable and wide-ranging of the...
A: a large number of GPS stations

Q: I have a test where I am given the following article, what is an answer for the question: What is the full name of the person who replaced wooden out defenses with strong, more impressive stone walls? ? Brougham Castle (pronounced ) is a medieval building about 2 miles (3.2 km) south-east of Penrith, Cumbria, England. The castle was founded by Robert I de Vieuxpont in the early 13th century. The site, near the confluence of the rivers, Eamont and Lowther, had been chosen by the Romans for a Roman fort called Brocavum. The castle is scheduled as an Ancient Monument, along with the fort, as "Brougham Roman fort and Brougham Castle".In its earliest form, the castle consisted of a stone keep, with an enclosure protected by an earthen bank and a wooden palisade. When the castle was built, Robert de Vieuxpont was one of the only lords in the region who were loyal to King John. The Vieuxponts were a powerful land-owning family in North West England, who also owned the castles of Appleby and Brough. In 1264, Robert de Vieuxpont's grandson, also named Robert, was declared a traitor, and his property was confiscated by Henry III. Brougham Castle and the other estates were eventually returned to the Vieuxpont family, and stayed in their possession, until 1269, when the estates passed to the Clifford family through marriage. With the outbreak of the Wars of Scottish Independence, in 1296, Brougham became an important military base for Robert Clifford, 1st Baron de Clifford. He began refortifying the castle: the wooden outer defences were replaced with stronger, more impressive stone walls, and a large stone gatehouse was added. The importance of Brougham and Robert Clifford was such that, in 1300, he hosted King Edward I of England at the castle. Robert's son, Roger Clifford, was executed as a traitor, in 1322, and the family estates passed into the possession of King Edward II of England, although they were returned once his son Edward III became king. The region was often at risk from the Scots, and in 1388, the castle was captured and sacked.
