Hello! I understand that Have been/Has been is used to indicate an action that started in the past and is continuing.
Hi
Anusreenair, Have been/Has been is basically present perfect and does
not necessarily suggest that the action is continuing.
For example:
Country X has been attacked only once in its history.This does not suggest that the attack is
still continuing.
Quote:
Eg- I have been practicing yoga since last monday.
Yes, this sentence (which is in
present perfect continuous tense) does suggest that the action (Yoga) started in the past and is continuing
Quote:
Hence does Option D not change the meaning?
Not at all. D just uses
present perfect (and not
present perfect continuous) and hence, does not necessarily suggest that the act of dating is still continuing. D basically just uses present perfect tense in
passive voice.
For example:
The University has declared the results.- Present perfect in active voice. Notice again that this does not necessarily suggest the the act of declaration of results in still continuing.
The results have been declared.- Present perfect in passive voice. Notice that this construct is similar to the construct used in option D. Again, this does not necessarily suggest the the act of declaration of results in still continuing.
