Problem: Suleiman the Magnificent (1520–1566) captured Belgrade in 1521, conquered the southern and central parts of the Kingdom of Hungary as part of the Ottoman–Hungarian Wars,[not in citation given] and, after his historical victory in the Battle of Mohács in 1526, he established Turkish rule in the territory of present-day Hungary (except the western part) and other Central European territories. He then laid siege to Vienna in 1529, but failed to take the city. In 1532, he made another attack on Vienna, but was repulsed in the Siege of Güns. Transylvania, Wallachia and, intermittently, Moldavia, became tributary principalities of the Ottoman Empire. In the east, the Ottoman Turks took Baghdad from the Persians in 1535, gaining control of Mesopotamia and naval access to the Persian Gulf. In 1555, the Caucasus became officially partitioned for the first time between the Safavids and the Ottomans, a status quo that would remain until the end of the Russo-Turkish War (1768–74). By this partitioning of the Caucasus as signed in the Peace of Amasya, Western Armenia, and Western Georgia fell into Ottoman hands, while Dagestan, Eastern Armenia, Eastern Georgia, and Azerbaijan remained Persian.
Suleiman the Magnificent had an important victory in what battle in 1526?
The answer is the following: Battle of Mohács

Problem: Cardigan formed up his unit and charged the length of the Valley of the Balaclava, under fire from Russian batteries in the hills. The charge of the Light Brigade caused 278 casualties of the 700-man unit. The Light Brigade was memorialized in the famous poem by Alfred Lord Tennyson, "The Charge of the Light Brigade." Although traditionally the charge of the Light Brigade was looked upon as a glorious but wasted sacrifice of good men and horses, recent historians say that the charge of the Light Brigade did succeed in at least some of its objectives. The aim of any cavalry charge is to scatter the enemy lines and frighten the enemy off the battlefield. The charge of the Light Brigade had so unnerved the Russian cavalry, which had previously been routed by the Heavy Brigade, that the Russian Cavalry was set to full-scale flight by the subsequent charge of the Light Brigade.:252
How many people did Cardigan lose during the Light Brigade?  
The answer is the following: 278

Problem: The Heian period (平安時代, Heian jidai?) is the last division of classical Japanese history, running from 794 to 1185. The period is named after the capital city of Heian-kyō, or modern Kyōto. It is the period in Japanese history when Buddhism, Taoism and other Chinese influences were at their height. The Heian period is also considered the peak of the Japanese imperial court and noted for its art, especially poetry and literature. Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic family who had intermarried with the imperial family. Many emperors actually had mothers from the Fujiwara family. Heian (平安?) means "peace" in Japanese.
The Heian period is named after what city?
The answer is the following: Heian-kyō

Problem: Persistent infections occur because the body is unable to clear the organism after the initial infection. Persistent infections are characterized by the continual presence of the infectious organism, often as latent infection with occasional recurrent relapses of active infection. There are some viruses that can maintain a persistent infection by infecting different cells of the body. Some viruses once acquired never leave the body. A typical example is the herpes virus, which tends to hide in nerves and become reactivated when specific circumstances arise.
How can some viruses main a persistent infection?
The answer is the following:
by infecting different cells of the body
