Task: Question Generation
Input (English): Passage: Some temples kept sacred animals, which were believed to be manifestations of the temple god's ba in the same way that cult images were. Each of these sacred animals was kept in the temple and worshipped for a certain length of time, ranging from a year to the lifetime of the animal. At the end of that time, it was replaced with a new animal of the same species, which was selected by a divine oracle or based on specific markings that were supposed to indicate its sacred nature. Among the most prominent of these animals were the Apis, a sacred bull worshipped as a manifestation of the  Memphite god Ptah, and the falcon at Edfu who represented the falcon god Horus.During the Late Period, a different form of worship involving animals developed. In this case, laymen paid the priests to kill, mummify, and bury an animal of a particular species as an offering to a god. These animals were not regarded as especially sacred, but as a species they were associated with the god because it was depicted in the form of that animal. The god Thoth, for instance, could be depicted as an ibis and as a baboon, and both ibises and baboons were given to him. Although this practice was distinct from the worship of single divine representatives, some temples kept stocks of animals that could be selected for either purpose. These practices produced large cemeteries of mummified animals, such as the catacombs around the Serapeum of Saqqara where the Apis bulls were buried along with millions of animal offerings.
Output (English): What was the name of the animal that was buried in the catacombs around the Serapeum of Saqqara?
