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'.

Let me give you an example: Passage: 'The size of a matrix is defined by the number of rows and columns that it contains. A matrix with m rows and n columns is called an m × n matrix or m-by-n matrix, while m and n are called its dimensions. For example, the matrix A above is a 3 × 2 matrix.'. Question: 'who came up with eating turkey on thanksgiving'.
The answer to this example can be: False
Here is why: The passage does not mention anything about Thanksgiving turkeys so the passage does not answer the question. The output is 'False', so this is a good example.
