In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Q: Passage: There is evidence of human settlement at Little Thetford since the Neolithic Age. A 1996 search along the Anglian Water pipeline at Little Thetford—Cawdle Fen uncovered an important and unusually dense concentration of late Neolithic (3000–2201 BC) remains. This is unusual because, although the fenland basin was dry and forested during the Mesolithic era, the area was sometimes subject to marine incursions, and at other times, fresh-water flooding. This led to marshes and open water areas which may have been difficult to settle on—except perhaps for seasonal activity. A Neolithic polished flint axe (4000–2201 BC) was found in the village in 1984 at Bedwell Hey Farm. Fourteen pre-Roman flints of various finishes were also discovered in 1998 at the same site.A more substantial Bronze Age settlement is known to have existed; the remains of what may have been a causeway were discovered in 1934, in the form of wooden piles unearthed by a farmer between Little Thetford and nearby Barway. A Bronze Age ring and a late Bronze Age sherd were excavated nearby. There have been a number of Bronze Age finds in the area, including a pre–701 BC palstave at nearby Fordey farm, Barway, and at Little Thetford, a middle Bronze Age (1600–1001 BC) rapier in 1953, and a late Bronze Age flesh-hook in 1929.A Romano-British farm around 200 AD, largely built upon a previous Iron Age settlement dating from 200–100 BC, was discovered during the Watson's Lane development in 1994. Pre-Roman Iron Age and Romano-British pottery was found on the site, as well as human skeletal remains. A single-flue-chamber tile kiln was also uncovered. Roofing tile fragments were found near the kiln, including tegulae, imbrices, lydions, pedales and sesquipedales. The Roman road Akeman Street is three-quarters of a mile (1.2 km) due west of the village.
