Q: Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.
A: When was the French and Indian War?
Rationale: This question is based on the following sentence in the passage- The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War.

Q: Before the introduction of the brown tree snake, Guam was home to several endemic bird species. Among them were the Guam rail (or ko'ko' bird in Chamorro) and the Guam flycatcher, both common throughout the island. Today the flycatcher is entirely extinct while the Guam rail is extinct in the wild but bred in captivity by the Division of Aquatic and Wildlife Resources. The devastation caused by the snake has been significant over the past several decades. As many as twelve bird species are believed to have been driven to extinction. According to many elders, ko'ko' birds were common in Guam before World War II.
A:
What are the names of the two native birds in Guam before the brown snake intrusion?
