input: Please answer the following: Extract the answer to the question from the following context. Question: What type of group of bird was mentioned? Context: It has been possible to teach a migration route to a flock of birds, for example in re-introduction schemes. After a trial with Canada geese Branta canadensis, microlight aircraft were used in the US to teach safe migration routes to reintroduced whooping cranes Grus americana.

input: Please answer the following: Extract the answer to the question from the following context. Question: If insulin/leptin function well, what result du they have? Context: Obesity can unfavourably alter hormonal and metabolic status via resistance to the hormone leptin, and a vicious cycle may occur in which insulin/leptin resistance and obesity aggravate one another. The vicious cycle is putatively fuelled by continuously high insulin/leptin stimulation and fat storage, as a result of high intake of strongly insulin/leptin stimulating foods and energy. Both insulin and leptin normally function as satiety signals to the hypothalamus in the brain; however, insulin/leptin resistance may reduce this signal and therefore allow continued overfeeding despite large body fat stores. In addition, reduced leptin signalling to the brain may reduce leptin's normal effect to maintain an appropriately high metabolic rate.

output: an appropriately high metabolic rate


input: Please answer the following: Extract the answer to the question from the following context. Question: What cukture dervied the term vacuum Context: Vacuum is space void of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum.

input: Please answer the following: Extract the answer to the question from the following context. Question: What has a C name and a Z name? Context: Parisians tend to share the same movie-going trends as many of the world's global cities, with cinemas primarily dominated by Hollywood-generated film entertainment. French cinema comes a close second, with major directors (réalisateurs) such as Claude Lelouch, Jean-Luc Godard, and Luc Besson, and the more slapstick/popular genre with director Claude Zidi as an example. European and Asian films are also widely shown and appreciated. On 2 February 2000, Philippe Binant realised the first digital cinema projection in Europe, with the DLP CINEMA technology developed by Texas Instruments, in Paris.
