In this task you will be given a question and a passage. You need to determine if the answer to the question is contained in the passage. If the answer can be found in the passage you should output 'True'. If the answer cannot be found in the passage you should output 'False'.

Example Input: Passage: '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).'. Question: 'cyanobacteria (blue-green algae) is an example of what type of plankton'.
Example Output: False

Example Input: Passage: 'The Nile has two major tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile (Amharic: ዓባይ, ʿĀbay) begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet just north of the Sudanese capital of Khartoum.'. Question: 'what is the main source of river nile'.
Example Output: True

Example Input: Passage: 'The presiding officer is the Speaker of the House, who is elected by the members thereof and is therefore traditionally the leader of the controlling party. He or she and other floor leaders are chosen by the Democratic Caucus or the Republican Conference, depending on whichever party has more voting members. The House meets in the south wing of the United States Capitol.'. Question: 'who elects the leader of the house of representatives'.
Example Output:
True
