**Объяснение:**
В этом задании нужно выбрать правильную форму глагола, ориентируясь на контекст предложения и на временные указатели, такие как "last summer" (прошлым летом) - Past Simple, "now" (сейчас), "yet", "already" - Present Perfect, "yesterday" (вчера) - Past Simple, "since Tuesday" (с вторника), "since 1998" (с 1998) - Present Perfect. Present Perfect используется для действий, которые начались в прошлом и имеют связь с настоящим, а Past Simple используется для действий, которые закончились в прошлом и не имеют связи с настоящим.
