Input: Read this: No single feature distinguishes Annelids from other invertebrate phyla, but they have a distinctive combination of features. Their bodies are long, with segments that are divided externally by shallow ring-like constrictions called annuli and internally by septa ("partitions") at the same points, although in some species the septa are incomplete and in a few cases missing. Most of the segments contain the same sets of organs, although sharing a common gut, circulatory system and nervous system makes them inter-dependent. Their bodies are covered by a cuticle (outer covering) that does not contain cells but is secreted by cells in the skin underneath, is made of tough but flexible collagen and does not molt on the other hand arthropods' cuticles are made of the more rigid -chitin, and molt until the arthropods reach their full size. Most annelids have closed circulatory systems, where the blood makes its entire circuit via blood vessels.
Question: What externally combines annelids' segments?

Output: unanswerable

Input: Read this: The Zhengde Emperor (r. 15051521), who enjoyed the company of lamas at court despite protests from the censorate, had heard tales of a "living Buddha" which he desired to host at the Ming capital; this was none other than the Rinpung-supported Mikyo Dorje, 8th Karmapa Lama then occupying Lhasa. Zhengde's top advisors made every attempt to dissuade him from inviting this lama to court, arguing that Tibetan Buddhism was wildly heterodox and unorthodox. Despite protests by the Grand Secretary Liang Chu, in 1515 the Zhengde Emperor sent his eunuch official Liu Yun of the Palace Chancellery on a mission to invite this Karmapa to Beijing. Liu commanded a fleet of hundreds of ships requisitioned along the Yangtze, consuming 2,835 g (100 oz) of silver a day in food expenses while stationed for a year in Chengdu of Sichuan. After procurring necessary gifts for the mission, he departed with a cavalry force of about 1,000 troops. When the request was delivered, the Karmapa lama refused to leave Tibet despite the Ming force brought to coerce him. The Karmapa launched a surprise ambush on Liu Yun's camp, seizing all the goods and valuables while killing or wounding half of Liu Yun's entire escort. After this fiasco, Liu fled for his life, but only returned to Chengdu several years later to find that the Zhengde Emperor had died.
Question: Who's company did the Zhengde Emperor enjoy?

Output: the company of lamas
