Definition: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: After Arghun's death, he was followed in rapid succession by two brief and fairly ineffective leaders, one of whom only held power for a few months. Stability was restored when Arghun's son Ghazan took power in 1295, though to secure cooperation from other influential Mongols, he made a public conversion to Islam when he took the throne, marking a major turning point in the state religion of the Ilkhanate. Despite being an official Muslim, however, Ghazan remained tolerant of multiple religions, and worked to maintain good relations with his Christian vassal states such as Cilician Armenia and Georgia.
In 1299, he made the first of what were to be three attempts to invade Syria. As he launched his new invasion, he also sent letters to the Franks of Cyprus (Henry II, King of Cyprus; and the heads of the military orders), inviting them to come join him in his attack on the Mamluks in Syria. The Mongols successfully took the city of Aleppo, and were there joined by their vassal King Hethum II, whose forces participated in the rest of the offensive. The Mongols soundly defeated the Mamluks in the Battle of Wadi al-Khazandar,  on December 23 or 24, 1299. This success in Syria led to wild rumors in Europe that the Mongols had successfully re-captured the Holy Land, and had even conquered the Mamluks in Egypt and were on a mission to conquer Tunisia in northern Africa. But in reality, Jerusalem had been neither taken nor even besieged. All that had been managed were some Mongol raids into Palestine in early 1300. The raids went as far as Gaza, passing through several towns, probably including Jerusalem. But when the Egyptians again advanced from Cairo in May, the Mongols retreated without resistance.In July 1300, the Crusaders launched naval operations to press the advantage. A fleet of sixteen galleys with some smaller vessels was equipped in Cyprus, commanded by King Henry of Cyprus, accompanied by his brother Amalric, Prince of Tyre, the heads of the military orders, and Ghazan's ambassador "Chial" (Isol the Pisan). The ships left Famagusta on July 20, 1300, to raid the coasts of Egypt and Syria: Rosette, Alexandria, Acre, Tortosa, and Maraclea, before returning to Cyprus.
Output:
What did the wild rumors in Europe claim the Mongols had successfully re-captured?
