[Q]: Passage: Persia attempted to ratify the Treaty of Constantinople , by demanding that the Ja'fari, also known as the Imamiyyah was to be accepted as a fifth legal sect of Islam. In 1743, Nader Shah declared war on the Ottoman Empire. He demanded the surrender of Baghdad. The Persians had captured Baghdad in 1623 and Mosul in 1624, but the Ottomans had recaptured Mosul in 1625 and Bagdad in 1638. The Treaty of Zuhab in 1639 between the Ottoman Empire and the Safavid Empire had resulted in peace for 85 years. After the fall of the Safavid Dynasty, Russia and the Ottoman Empire agreed to divide the northwest and the Caspian region of Persia, but with the advent of Nader Shah, the Russians and the Turks withdrew from the region. Nader Shah waged war against the Ottomans from 1730 to 1736 but it ended with a stalemate. Nader Shah afterwards turned east and declared war on the Moghul Empire and invaded India, in order to refund his wars against the Ottomans.
Question: How many years did Nader Shah wage war against the Ottomans?

[Q]: Passage: On 8 April 1918, after the defeat in Tampere and the German army intervention, the People's Delegation retreated from Helsinki to Vyborg. The loss of Helsinki pushed them to Petrograd on 25 April. The escape of the leadership embittered many Reds, and thousands of them tried to flee to Russia, but most of the refugees were encircled by White and German troops. In the Lahti area they surrendered on 1-2 May. The long Red caravans included women and children, who experienced a desperate, chaotic escape with severe losses due to White attacks. The scene was described as a "road of tears" for the Reds, but for the Whites, the sight of long, enemy caravans heading east was a victorious moment. The Red Guards' last strongholds between the Kouvola and Kotka area fell by 5 May, after the Battle of Ahvenkoski. The war of 1918 ended on 15 May 1918, when the Whites took over Fort Ino, a Russian coastal artillery base on the Karelian Isthmus, from the Russian troops. White Finland and General Mannerheim celebrated the victory with a large military parade in Helsinki on 16 May 1918. The Red Guards had been defeated. The initially pacifist Finnish labour movement had lost the Civil War, several military leaders committed suicide and a majority of the Reds were sent to prison camps. The Vaasa Senate returned to Helsinki on 4 May 1918, but the capital was under the control of the German army. White Finland had become a protectorate of the German Empire and General Rüdiger von der Goltz was called "the true Regent of Finland". No armistice or peace negotiations were carried out between the Whites and Reds and an official peace treaty to end the Finnish Civil War was never signed.
Question: Who stopped the Reds from fleeing?
[A]:
span
