Объяснение:

Present Perfect употребляется, когда мы говорим о действиях в без указания времени совершения действия. Past Simple употребляется, когда мы называем точное время совершения действия.
Present Perfect употребляется, когда действие еще продолжается в настоящем или произошло в еще не законченный период времени (в предложении есть today, this week и т. п.). Past Simple употребляется, когда действие уже закончилось и не имеет связи с настоящим (в предложении есть слова yesterday, last week, выражения со словом ago и т. д.)
