Montana's motto, Oro y Plata, Spanish for "Gold and Silver", recognizing the significant role of mining, was first adopted in 1865, when Montana was still a territory. A state seal with a miner's pick and shovel above the motto, surrounded by the mountains and the Great Falls of the Missouri River, was adopted during the first meeting of the territorial legislature in 1864–65. The design was only slightly modified after Montana became a state and adopted it as the Great Seal of the State of Montana, enacted by the legislature in 1893. The state flower, the bitterroot, was adopted in 1895 with the support of a group called the Floral Emblem Association, which formed after Montana's Women's Christian Temperance Union adopted the bitterroot as the organization's state flower. All other symbols were adopted throughout the 20th century, save for Montana's newest symbol, the state butterfly, the mourning cloak, adopted in 2001, and the state lullaby, "Montana Lullaby", adopted in 2007.

Leonardo Bruni was the first historian to use tripartite periodization in his History of the Florentine People (1442). Flavio Biondo used a similar framework in Decades of History from the Deterioration of the Roman Empire (1439–1453). Tripartite periodization became standard after the German historian Christoph Cellarius published Universal History Divided into an Ancient, Medieval, and New Period (1683).

William Henry Perkin studied and worked at the college under von Hofmann, but resigned his position after discovering the first synthetic dye, mauveine, in 1856. Perkin's discovery was prompted by his work with von Hofmann on the substance aniline, derived from coal tar, and it was this breakthrough which sparked the synthetic dye industry, a boom which some historians have labelled the second chemical revolution. His contribution led to the creation of the Perkin Medal, an award given annually by the Society of Chemical Industry to a scientist residing in the United States for an "innovation in applied chemistry resulting in outstanding commercial development". It is considered the highest honour given in the industrial chemical industry.
What discovery by von Hoffman was prompted by his work with Perkins?
A: unanswerable

By the early 18th century, the Maratha Kingdom had transformed itself into the Maratha Empire under the rule of the Peshwas (prime ministers). In 1737, the Marathas defeated a Mughal army in their capital, Delhi itself in Battle of Delhi (1737). The Marathas continued their military campaigns against Mughals, Nizam, Nawab of Bengal and Durrani Empire to further extend their boundaries. Gordon explained how the Maratha systematically took control over new regions. They would start with annual raids, followed by collecting ransom from villages and towns while the declining Mughal Empire retained nominal control and finally taking over the region. He explained it with the example of Malwa region. Marathas built an efficient system of public administration known for its attention to detail. It succeeded in raising revenue in districts that recovered from years of raids, up to levels previously enjoyed by the Mughals. For example, the cornerstone of the Maratha rule in Malwa rested on the 60 or so local tax collectors who advanced the Maratha ruler Peshwa a portion of their district revenues at interest. By 1760, the domain of the Marathas stretched across practically the entire subcontinent. The north-western expansion of the Marathas was stopped after the Third Battle of Panipat (1761). However, the Maratha authority in the north was re-established within a decade under Peshwa Madhavrao I. The defeat of Marathas by British in third Anglo-Maratha Wars brought end to the empire by 1820. The last peshwa, Baji Rao II, was defeated by the British in the Third Anglo-Maratha War. With the defeat of the Marathas, no native power represented any significant threat for the British afterwards.
In the end, what empire defeated the Maratha Empire?
A:
British
