Explanation:

The original text talks about paranormal investigators using special equipment and psychics (humans with supernatural connection) to investigate hauntings. The first option says they may use humans (like psychics) to determine ghost presence, which aligns with the text's mention of using a psychic. Other options introduce new info not in the original (scientific verification, people's wonder, researching location history) so they don't belong in a summary of the given text.

Answer:

A. Paranormal investigators may also use humans to help them determine whether a ghost is present.
