When we say something has been "brought in to question", it often means that doubts or uncertainties have been raised about its validity, accuracy, or authenticity. To express the same idea in different words, we could use synonyms such as "cast doubt on", "challenged", "disputed" or "called into doubt". Other options might include "debated", "contested", "questioned", or "scrutinized". Ultimately, the choice of what term to use will depend on the context and tone of the discussion, as well as the specific details of the situation being described.
