In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.

Input: Consider Input: The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (or catheti, singular: cathetus). Side a may be identified as the side adjacent to angle B and opposed to (or opposite) angle A, while side b is the side adjacent to angle A and opposed to angle B.

Output: what are the sides of a right triangle called


Input: Consider Input: Cross-validation, sometimes called rotation estimation, or out-of-sample testing is any of various similar model validation techniques for assessing how the results of a statistical analysis will generalize to an independent data set. It is mainly used in settings where the goal is prediction, and one wants to estimate how accurately a predictive model will perform in practice. In a prediction problem, a model is usually given a dataset of known data on which training is run (training dataset), and a dataset of unknown data (or first seen data) against which the model is tested (called the validation dataset or testing set )., The goal of cross-validation is to test the model's ability to predict new data that was not used in estimating it, in order to flag problems like overfitting or selection bias and to give an insight on how the model will generalize to an independent dataset (i.e., an unknown dataset, for instance from a real problem).

Output: cross-validation of findings from a prediction study is particularly important for


Input: Consider Input: The most recognizable symbol of the organization is the blue corduroy FFA jacket that is worn by current FFA members. The back of the jacket features a large FFA emblem just underneath the name of each FFA member's state. The name of the local FFA chapter, district, region or area is embroidered below the emblem. The front of the FFA jacket features a smaller FFA emblem on the left chest and the FFA member's name and sometimes, if applicable, office and year on the right chest. FFA members are required to wear the FFA jacket as part of official dress while participating in all official organization activities.


Output: what is the symbol for the president in ffa
