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: Taapaca is part of the Central Volcanic Zone of the Andes, which along with the Northern Volcanic Zone, the Southern Volcanic Zone and the Austral Volcanic Zone is one of the four volcanic belts of the Andes; these volcanic belts are separated by areas where no recent volcanism has occurred.The Central Volcanic Zone has about 44 active volcanoes and several other caldera/ignimbrite and volcanic field centres. Older volcanoes are often well preserved owing to the dry climate. This volcanic zone features the highest volcanoes in the world, which reach elevations of 5,000–7,000 metres (16,000–23,000 ft) here. The largest historical eruption in the Central Volcanic Zone occurred at Huaynaputina in 1600 and Lascar is the most active volcano in the region; otherwise volcanic activity is poorly recorded as most edifices are remote from human habitation.Taapaca is located on the western margin of the Altiplano, where the Western Cordillera has developed since the Oligocene. The basement beneath the volcano is formed by several principally volcanic formations, including the Lupica and sedimentary Huaylas formations and the Lauca ignimbrite (2.72 million years old); this basement is of Oligocene to Pliocene age. In some places, a Proterozoic basement formed by amphibolites, gneisses and serpentinites crops out. The volcanoes of Condoriri, Pomerape, Larancagua and Parinacota lie to the east of Taapaca. The area of the volcano is subject to contractional tectonics, with a major thrust fault passing close by, but their relationship to Taapaca's volcanism is not clear.
Output:
What volcanic belts are separated by areas where no recent volcanism has occurred?
