Question

choose the word or phrase that best completes each sentence.
caesar augustus made sure that the central government controlled tax collection.
engineers built the field of mars, which had government offices and statues.
a blank was created to improve communication.
caesar augustus ordered the construction of blank, which improved water supplies and provided w crops.

Explanation:

This problem is about Roman history (Caesar Augustus, engineering projects, communication, water supplies), so the relevant subfield in Social Science is History. For the blanks:

1. "Engineers built the Field of Mars" – the Field of Mars (Campus Martius) in Rome had government offices and statues, so that's correct.
2. For "A ____ was created to improve communication" – likely "road system" (Roman roads improved communication).
3. For "Caesar Augustus ordered the construction of ____, which improved water supplies..." – likely "aqueducts" (Roman aqueducts improved water supply for cities and agriculture).

Answer:

1. Field of Mars (correct as filled).
2. road system (for the "A ____ was created to improve communication" blank).
3. aqueducts (for the "Caesar Augustus ordered the construction of ____..." blank).
