Problem: Police:

In 1566, the first police investigator of Rio de Janeiro was recruited. By the 17th century, most captaincies already had local units with law enforcement functions. On July 9, 1775 a Cavalry Regiment was created in the state of Minas Gerais for maintaining law and order. In 1808, the Portuguese royal family relocated to Brazil, because of the French invasion of Portugal. King João VI established the "Intendência Geral de Polícia" (General Police Intendancy) for investigations. He also created a Royal Police Guard for Rio de Janeiro in 1809. In 1831, after independence, each province started organizing its local "military police", with order maintenance tasks. The Federal Railroad Police was created in 1852.

As Charles Town grew, so did the community's cultural and social opportunities, especially for the elite merchants and planters. The first theatre building in America was built in 1736 on the site of today's Dock Street Theatre. Benevolent societies were formed by different ethnic groups, from French Huguenots to free people of color to Germans to Jews. The Charles Towne Library Society was established in 1748 by well-born young men who wanted to share the financial cost to keep up with the scientific and philosophical issues of the day. This group also helped establish the College of Charles Towne in 1770, the oldest college in South Carolina. Until its transition to state ownership in 1970, this was the oldest municipally supported college in the United States.

Question: Believed to be a stowaway on a U.S. military transport near the end of World War II, the brown tree snake (Boiga irregularis) was accidentally introduced to Guam, that previously had no native species of snake. It nearly eliminated the native bird population. The problem was exacerbated because the reptile has no natural predators on the island. The brown tree snake, known locally as the kulebla, is native to northern and eastern coasts of Australia, Papua New Guinea, and the Solomon Islands. While slightly venomous, the snake is relatively harmless to human beings. Although some studies have suggested a high density of these serpents on Guam, residents rarely see the nocturnal creatures. The United States Department of Agriculture has trained detector dogs to keep the snakes out of the island's cargo flow. The United States Geological Survey also has dogs capable of detecting snakes in forested environments around the region's islands.
Is there an answer to this question: Where was the U.S. military transport ultimately headed when it accidentally introduced the brown tree snake to Guam?

Answer: unanswerable
