The text passage contains a problem statement and a series of test cases for a solution to the problem. The problem is to find common elements in the rows of a matrix, and the test cases check the solution against various input matrices.
no_question

the passage does not contain a mathematical question that requires an answer. instead, it provides a problem statement and test cases to verify a solution.
Given a text passage, determine:
    1. If it contains a mathematical question (including word problems or calculations)
    2. If an answer to that mathematical question is provided in the text

First, describe the content structure you found in 1-2 sentences.

Then provide your analysis in the following format:
TYPE: <one of the following values>
- NO_QUESTION
- SINGLE_QUESTION
- SINGLE_QUESTION_WITH_ANSWER
- MULTIPLE_QUESTIONS
