In these three underlined parts, two are used as Present Perfect(PP) and one as Present Perfect Progressive(PPP).
I have no problem with two PPs, but with a PPP.
Is this PPP can also be used as PP?
(Is this possible?)
Actually in my grammatical sense it's awkward to use this PPP as PP, but I can not explain. Can you give me your thoughts?
(Thanks a lot.)
And if my grammatical sense is wrong, that means both PPP and PP can be used interchangeably in this context.
(If it is, tell me so.)
Lastly even though the two uses of tense is interchangeable, is there any reason the author of this sentence used PPP?
(I know my questions seems to do with too many trifling details. But TENSE is terribly hard subject to anyone learning English as a foreign language. So excuse all my petty questions.)
