Task: Question Generation
Input (English): Passage: In February 1918 the Red Army overthrew the White Russian-supported Kokand autonomy of Turkestan. Although this move seemed to solidify Bolshevik power in Central Asia, more troubles soon arose for the Red Army as the Allied Forces began to intervene. British support of the White Army provided the greatest threat to the Red Army in Central Asia during 1918. Great Britain sent three prominent military leaders to the area. One was Lt. Col. Bailey, who recorded a mission to Tashkent, from where the Bolsheviks forced him to flee. Another was Gen. Malleson, leading the Malleson Mission, who assisted the Mensheviks in Ashkhabad  with a small Anglo-Indian force. However, he failed to gain control of Tashkent, Bukhara and Khiva. The third was Maj. Gen. Dunsterville, who the Bolsheviks drove out of Central Asia only a month after his arrival in August 1918. Despite setbacks due to British invasions during 1918, the Bolsheviks continued to make progress in bringing the Central Asian population under their influence. The first regional congress of the Russian Communist Party convened in the city of Tashkent in June 1918 in order to build support for a local Bolshevik Party.
Output (English): How many regions had Gen. Malleson fail to gain control of?
