Step-by-step explanation:
The statement is True.
Illinois is considered a "hotbed of extra-terrestrial speculation" with six of the ten most widely-spotted UFO events occurring in the state. This information is supported by the reference provided which states that not every UFO report has been explained and investigation often converts them to identified flying objects (IFOs) or not-at-all flying objects (NFOs).
