Questions & Answers about Колонны, восстановленные археологами, стоят вдоль улицы.
How would this sentence look if we expanded the participle back into a который clause?
You could say Колонны, которые были восстановлены археологами (passive: which were restored by the archaeologists) or Колонны, которые восстановили археологи (active: which the archaeologists restored). The participle восстановленные is a formal, concise way to express either of these.
How do we know which ending to use for восстановленные?
Past passive participles behave just like adjectives and must agree with the noun they describe in gender, number, and case. Because it modifies Колонны (nominative plural), the participle takes the nominative plural ending -ые.
Why is археологами in the instrumental case?
In passive constructions, the doer of the action (the agent) is always put in the instrumental case. Because the columns were restored by the archaeologists, археологи becomes археологами.
Are the commas around восстановленные археологами strictly necessary?
Yes. In Russian, a participial phrase must be set off by commas if it comes immediately after the noun it modifies. If you moved the phrase before the noun (Восстановленные археологами колонны стоят...), the commas would disappear.
Why does the sentence use улицы instead of the nominative or accusative ?
