However, leeches and their closest relatives have a body structure that is very uniform within the group but significantly different from that of other annelids, including other members of the Clitellata. In leeches there are no septa, the connective tissue layer of the body wall is so thick that it occupies much of the body, and the two coelomata are widely separated and run the length of the body. They function as the main blood vessels, although they are side-by-side rather than upper and lower. However, they are lined with mesothelium, like the coelomata and unlike the blood vessels of other annelids. Leeches generally use suckers at their front and rear ends to move like inchworms. The anus is on the upper surface of the pygidium.
What type of annelids are very different from others?
leeches and their closest relatives

Input: Yale University
Several campus safety strategies have been pioneered at Yale. The first campus police force was founded at Yale in 1894, when the university contracted city police officers to exclusively cover the campus. Later hired by the university, the officers were originally brought in to quell unrest between students and city residents and curb destructive student behavior. In addition to the Yale Police Department, a variety of safety services are available including blue phones, a safety escort, and 24-hour shuttle service.

Who were the the first campus police composed of?
Output: city police officers

Input: Article: Archaeology confirms the widespread use of binding spells (defixiones), magical papyri and so-called "voodoo dolls" from a very early era. Around 250 defixiones have been recovered just from Roman Britain, in both urban and rural settings. Some seek straightforward, usually gruesome revenge, often for a lover's offense or rejection. Others appeal for divine redress of wrongs, in terms familiar to any Roman magistrate, and promise a portion of the value (usually small) of lost or stolen property in return for its restoration. None of these defixiones seem produced by, or on behalf of the elite, who had more immediate recourse to human law and justice. Similar traditions existed throughout the empire, persisting until around the 7th century AD, well into the Christian era.

Now answer this question: What was the term for binding spells in the Roman world?

Output: defixiones

Article: Theoretical analyses show that detours that increase flight distance by up to 20% will often be adaptive on aerodynamic grounds - a bird that loads itself with food to cross a long barrier flies less efficiently. However some species show circuitous migratory routes that reflect historical range expansions and are far from optimal in ecological terms. An example is the migration of continental populations of Swainson's thrush Catharus ustulatus, which fly far east across North America before turning south via Florida to reach northern South America; this route is believed to be the consequence of a range expansion that occurred about 10,000 years ago. Detours may also be caused by differential wind conditions, predation risk, or other factors.

Question: What kind of bird flies less efficiently?
Ans: a bird that loads itself with food
