Listing says parcel conveying with property?

[Chris M.]

I saw a listing that’s states “there is another +/- 8 acre parcel conveying with this property”.  And that is currently used for livestock.  The listing description says 8.5 acres.  Then in the facts it shows 16.5 acres (I’m assuming conveyed parcel included).  What does this mean?   If I were to buy this property do I own this converting land?  is the neighboring farm currently using this land?
