Correct Sentences:

1. 1. b) She's been to the doctor's. She was there last Friday. (Using 'been to' indicates a completed visit, and 'was there' specifies the time of the visit. 'Gone to' would imply she is still at the doctor's.)
2. 2. b) They're not here. They've been joining the party. ('Been joining' implies they are currently participating in the party, which is why they are not here.)
3. 3. a) I've been to two shops, but I didn't find any fresh vegetables. ('Been to' refers to visiting places, and 'didn't find' correctly indicates the absence of vegetables.)
4. 4. b) Has he ever been to Greece? ('Been to' is used to ask about experience of visiting a place.)
5. 5. b) They're on holiday. They've been to the USA for a week. ('Been to' indicates visiting a place as part of their holiday.)

Explanation: The correct sentences were identified based on the proper use of the present perfect simple ('have/has been') and present perfect continuous ('have/has been -ing') tenses, and the distinction between 'gone to' and 'been to' when discussing travel and visits.
