An archaeological team has been excavating three ancient village sites—Barras, Agna, and Cussaia—looking in particular at kitchen waste dumps as a way to understand the villages' dietary patterns and trading relationships. What follows are brief summaries of their findings.
Barras: The best data come from stratified finds in this oceanside village, which was inhabited from AD 600 to 1300 and was the only one of the three villages to produce seafood, its main dietary item. Though Barras residents hunted on land and raised crops, this provided relatively small amounts of food. As Barras's overall prosperity rose, there was more food available per person, and its population increased from an average of 100 residents in the AD 600s to 400 residents in the AD 1000s to 600 residents in the AD 1200s.
Agna: Agna was established in an inland forest around AD 800 and its residents mainly hunted but also ate considerable amounts of fruit, nuts, and other forest-vegetable products. They also traded meat to Barras for other goods. With no open fields, Agna grew no grain.
Cussaia: Predating Barras, Cussaia depended heavily on raising grain crops and eventually obtained seafood and meat via trade. It traded directly only with Barras, because a mountain range separated it from Agna, though some products may have been traded between Agna and Cussaia via Barras.
Additionally, there is no evidence that any other village traded with Barras, Agna, or Cussaia prior to AD 1300.
Assume that any increase of 5% or more from one century to the next in the amount of a given food consumed by Barras residents is due primarily to a corresponding increase in imports of that food into Barras from other villages. Given this assumption and the information provided, for each of the following, select Yes if it describes a food likely imported by Barras during times of increased food consumption. Otherwise select No.
Meat from Agna from the AD 500s to the AD 600s
Meat from Agna from the AD 800s to the AD 900s
Grain from Cussaia from the AD 600s to the AD 700s

Summary: Archaeological data reveals three ancient villages with distinct dietary specializations based on geography (coastal seafood, forest hunting, agricultural grain) forming a closed trading network centered on Barras.
Table Analysis:
Summary: Barras maintained seafood as its primary food source throughout its history, but the establishment of trade with Agna caused a dramatic temporary increase in meat consumption during the 900s-1000s.
Table Analysis:
Summary: Consumption data confirms the interdependent trade relationship between villages, with Barras maintaining stable seafood access while Agna's seafood consumption depended entirely on trade, leading to vulnerability during disruptions.
For each given food and century-to-century period, determine if Barras imported that food based on whether the consumption increased by 5% or more, which would indicate imports from other villages.
Key constraints:
Answer type needed: Yes/No determinations for each statement
Using food consumption data and village establishment timelines to verify if consumption changes meet threshold and if trade relationships existed, allowing determination of import status for the specified statements.
The analysis can be completed using consumption data and trade timelines, which fully support evaluation of all three statements.
Assessing three statements about Barras food imports by calculating consumption increases and verifying presence of trade partners over the relevant centuries.
Hypothesis: Increase of 5% or more in consumption from one century to the next implies import from the named village.
Increase threshold: 5%
Did Barras import meat from Agna between AD 500s and AD 600s due to a consumption increase of 5% or more?
Answer: NO - Agna did not exist in 500s-600s, so imports could not have occurred.
Did Barras import meat from Agna between AD 800s and AD 900s due to a consumption increase of 5% or more?
Answer: YES - Large increase and Agna was an active meat trade partner in this period.
Did Barras import grain from Cussaia between AD 600s and AD 700s due to a consumption increase of 5% or more?
Answer: YES - Significant increase and Cussaia traded grain to Barras at this time.
Verifying findings against historical data and village trade relations:
Meat from Agna from the AD 500s to the AD 600s
Meat from Agna from the AD 800s to the AD 900s
Grain from Cussaia from the AD 600s to the AD 700s
