On 17 April 1861, five days after the Confederate attack on Fort Sumter, the legislature voted to secede from the United States and joined the Confederacy. Official action came in May, after the Confederacy promised to move its national capital to Richmond. The city was at the end of a long supply line, which made it somewhat difficult to defend, although supplies continued to reach the city by canal and wagon for years, since it was protected by the Army of Northern Virginia and arguably the Confederacy's best troops and commanders. It became the main target of Union armies, especially in the campaigns of 1862 and 1864-5.
After leaving the Union, what nation did Virginia join?
****
The answer: Confederacy

The length and nature of parental care varies widely amongst different orders and species. At one extreme, parental care in megapodes ends at hatching; the newly hatched chick digs itself out of the nest mound without parental assistance and can fend for itself immediately. At the other extreme, many seabirds have extended periods of parental care, the longest being that of the great frigatebird, whose chicks take up to six months to fledge and are fed by the parents for up to an additional 14 months. The chick guard stage describes the period of breeding during which one of the adult birds is permanently present at the nest after chicks have hatched. The main purpose of the guard stage is to aid offspring to thermoregulate and protect them from predation.
What is the period of breeding during which one of the adult birds is always present at the nest?
****
The answer: chick guard stage
