You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.

Input: Consider Input: The EF of the left heart, known as the left ventricular ejection fraction (LVEF), is calculated by dividing the volume of blood pumped from the left ventricle per beat (stroke volume) by the volume of blood collected in the left ventricle at the end of diastolic filling (end-diastolic volume). LVEF is an indicator of the effectiveness of pumping into the systemic circulation. The EF of the right heart, or right ventricular ejection fraction (RVEF), is a measure of the efficiency of pumping into the pulmonary circulation. A heart which cannot pump sufficient blood to meet the body's requirements (i.e., heart failure) will often, but not invariably, have a reduced ventricular ejection fraction.

Output: is ejection fraction the same as stroke volume?


Input: Consider Input: In mathematical analysis, the maxima and minima (the respective plurals of maximum and minimum) of a function, known collectively as extrema (the plural of extremum), are the largest and smallest value of the function, either within a given range (the local or relative extrema) or on the entire domain of a function (the global or absolute extrema). Pierre de Fermat was one of the first mathematicians to propose a general technique, adequality, for finding the maxima and minima of functions.

Output: is relative extrema the same as local extrema?


Input: Consider Input: The group keeps searching for Sophia but is unsuccessful. In the episode ``Cherokee Rose'', Carl's injuries ultimately lead the whole group onto Hershel Greene's farm, where they settle. They continue their search, but still nothing seems to turn up. In the episode ``Chupacabra'', the only thing that comes to light is Sophia's doll, which had been discovered by a member of the group named Daryl Dixon. Daryl goes on several searches for Sophia, being one of the most devoted members of the group in looking towards recovering her. He and Carol bond greatly because of his efforts. In the mid-season finale ``Pretty Much Dead Already'', Glenn tells the group that he discovered that Hershel has been keeping a group of walkers, consisting largely of his family and neighbors, in his barn, as he had believed them to be sick but nonetheless curable patients. Shane goes against Rick's orders, opens the barn, and (along with the rest of the group) shoots all the walkers that stumble out. Just as things seem to be over and done with, one more walker stumbles out of the barn - Sophia, who had been bitten while in the woods. (She had then been found by Otis, who put her zombified form in the barn before his death.) Knowing what must be done, Rick steps forward and shoots her, putting her out of her misery. In the mid-season premiere ``Nebraska'', she is buried in a funeral ceremony, alongside Hershel's second wife Annette and stepson Shawn (who were also kept in his barn as walkers). Carol does not attend the funeral because her daughter ``died a long time ago''.


Output: do they find sophia on the walking dead?
