We previously mentioned that if a Russian number phrase is the subject of a verb, except when the number ends in one, it induces neuter singular verb agreement in the past:
| Прошло два года. |
Two years went by. |
| Прошло пять лет. |
Five years went by. |
| Прошло десять лет. |
Ten years went by. |
There is another exception. If the number is preceded by an adjective in the nominative plural, then the verb shows plural agreement in the past:
| Эти два года были очень насыщенными. (adapted from this source) |
Those two years were very rich. |
| Все эти пять лет были удачными в финансовом отношении. |
All five years were profitable. |
| Те десять лет прошли прекрасно. (adapted from source) |
Those ten years went by marvelously. |
