Problem: Text: A zebroid (also zedonk, zenkey, zorse, zebra mule, zonkey, and zebmule) is the offspring of any cross between a zebra and any other equine: essentially, a zebra hybrid. In most cases, the sire is a zebra stallion. Offspring of a donkey sire and zebra dam, called a zebra hinny, or donkra, do exist but are rare and are usually sterile and infertile. Zebroids have been bred since the 19th century. Charles Darwin noted several zebra hybrids in his works.

Question: can you breed a zebra and a horse?

OPTIONS:
- no
- yes
A: yes

Problem: Text: The Union and Confederacy quickly raised volunteer and conscription armies that fought mostly in the South over the course of four years. The Union finally won the war when General Robert E. Lee surrendered to General Ulysses S. Grant at the Battle of Appomattox Court House, followed by a series of surrenders by Confederate generals throughout the southern states. Four years of intense combat left 620,000 to 750,000 people dead, more than the number of U.S. military deaths in all other wars combined (at least until approximately the Vietnam War). Much of the South's infrastructure was destroyed, especially the transportation systems. The Confederacy collapsed, slavery was abolished, and 4 million slaves were freed. The Reconstruction Era (1863--1877) overlapped and followed the war, with the process of restoring national unity, strengthening the national government, and granting civil rights to freed slaves throughout the country. The Civil War is the most studied and written about episode in U.S. history.

Question: was most of the civil war fought on confederate soil?

OPTIONS:
- no
- yes
A: yes

Problem: Text: Half-mast or half-staff refers to a flag flying below the summit on a pole. In many countries this is seen as a symbol of respect, mourning, distress, or, in some cases, a salute.
