Объяснение:
Обычно, если указано время выполнения действия (например: yesterday, last summer, two years ago и т.д.), то мы употребляем Past Simple. (Глагол во 2 форме или с окончанием -ed)
Если у нас есть результат действия в настоящем, при этом время его выполнения не указано, плюс у нас есть такие слова, как yet, already, just и т.п., то мы используем Present Perfect. (have/has + глагол в 3 форме или с окончанием -ed)
