You will be given a definition of a task first, then some input of the task.
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.

Passage: On the night of 6 November 1995, a fire broke out in the Rova compound, destroying or severely damaging all of its buildings. Once the flames had been extinguished, all that remained of the original structures were the stone shells of the royal chapel and Manjakamiadana. Fire-fighters arrived late at the scene. Their capacity to douse the fire was hampered by the discovery that their fire hoses did not properly fit onto the nearby hydrants. In addition, the water pressure at the hydrants was significantly reduced due to Analamanga hilltop's high elevation. As the fire-fighters battled the flames, numerous bystanders ran into Rova compound buildings to retrieve artefacts of historic and cultural significance. Approximately 1,675 objects were saved out of an estimated total of 6,700. Some pillaging is believed to have occurred. On the night of the fire, the body of one of the queens was found in the public square in the centre of the city. A funeral vigil was held the following day for these royal remains. The remains were later identified as belonging to Ranavalona III, and have since been re-interred in the royal tombs at Ambohimanga.The destruction of the Rova of Antananarivo occurred at a time when the complex was in the final stages of the process to become classified as Madagascar's first cultural UNESCO World Heritage Site. Six people were initially charged in connection with the Rova's destruction in an Antananarivo court of law, but the official investigation concluded that the fire was an accident. Public accusations of a cover-up placed the blame for the fire on government officials, various ethnic groups, foreign powers and other parties. Widespread belief persists within and outside Madagascar that a deliberate arson was the cause. Rumoured motivations for arson at the Rova were numerous and remain unproven. The revelation that important financial archives had been destroyed early on the morning of the fire sparked rumours that corrupt government officials had lit the blaze to create a public distraction from their illicit activities. Other explanations have included popular dissatisfaction with the election of divisive mayor Guy Willy Razanamasy or a flare-up of long-standing tensions among coastal peoples resentful of Merina socio-political domination. Accusations were also made against both then-president Albert Zafy and his predecessor, Didier Ratsiraka. The debate over why and how the Rova burned remains an unresolved and highly contentious subject decades later.
Output:
How many cultural and historical objects were involved in the fire at the Rova compound?
