[EX Q]: Passage: 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. Question: What is Montana's motto?

Oro y Plata
