Answer 2

The first answer (has picked) is a little awkward although not technically wrong, it means that she picked the apples at some point in the past (not today, or that the speaker is tryin to make a pont ie, Mandy has picked apples all afternoon. Of course she is tired.).

Has been picking means that she continues to pick the apples as the afternoon continues (a long term statement and a bit weak, but it could be used even if she is done ie Mandy has been picking apples all afternoon. She has earned a break.).

The first two answers are very similar in feeling, meaning and use.The second one is usually more correct than the first one.

Picked means that she is done and the action was completed already.

Not sure what you are supposed to do, they are all valid English sentences but the last one is the most active and strongest.

Answer 3

The sentence is a bit ambiguous. I don't know what you are looking for.

To say that "Mandy has been picking apples all afternoon", this could imply that she is still performing the action of picking apples.

To say that "Mandy picked apples all afternoon" more or less implies that she is no longer picking apples.

To say that "Mandy has picked apples all afternoon" sounds redundant. I don't think "has" is necessary.

Answer 4

Mandy has been picking apples all afternoon.

Has is the past tense of the action of picking.

Answer 5

21.Mandy has been picking apples all afternoon.
