The following sentences are from a draft of an essay about ancient Roman engineering. To ensure that the paragraph is organized logically and that each claim is supported by immediate, relevant evidence and details, in what order should the sentences be placed?
- 1Ancient Roman builders constructed monumental aqueducts that relied entirely on gravity to transport water from distant freshwater springs to growing urban centers.
- 2To keep the water flowing continuously without pooling or spilling, engineers had to maintain a remarkably precise and consistent downward gradient.
- 3They achieved this precision using the chorobates, a twenty-foot-long wooden leveling device that measured slope with water-filled grooves.
- 4With this tool, surveyors could establish gradients as gentle as one foot of drop for every several thousand feet of distance, ensuring a steady, controlled flow of water.
Answer
The sentences should be arranged in the order: introduction of gravity-fed aqueducts, explanation of the gradient requirement, introduction of the chorobates leveling tool, and detail of the specific gradient measurements achieved.
The correct logical order begins with the introductory statement about gravity-fed aqueducts, followed by the requirement of a precise downward gradient. Next, the tool (chorobates) used to achieve this precision is introduced. Finally, the specific gradient measurements achieved with this tool are detailed.
