Hi,
I have some doubts on the usage of HAVE BEEN:
1. The recent amendments to the rules governing professional baseball, like those governing professional gymnastics, were motivated by a desire to make the sport more interesting to watch.
A)
B) those to the rules governing professional gymnastics, were motivated
C) those to the rules which govern professional gymnastics, were motivated
D) the amendments to the rules governing professional gymnastics, have been motivated
E) the amendments governing professional gymnastics, were being motivated
OA is B. When I googled this, I found that:
Here in D, HAVE BEEN indicates that the amendments are still happening. So, D is incorrect.
2. Scientists are currently trying to determine the extent to which tectonic plates have been shifted from their previous positions by earthquakes and other similar phenomena.
A. to which tectonic plates have been shifted
B. to which tectonic plates have shifted
C. of the shift of tectonic plates
D. of tectonic plate shifting
E. that tectonic plates have been shifted
OA is A.
I am confused why different answers for same usage and same passive strutures.
Please explain.

I have had three bikes. I had one when I was twelve.
Billy has already eaten. He ate lunch this afternoon.
Our nation has had a number of crisis points threatening its existence. The first was the Civil War.
In each of the first sentences, we have no time cues; the sentence gives no indication when Billy ate lunch, I owned a bike, or the nation faced a crisis. Thus, we use the present perfect.
In each of the second sentences, we have a time cue: 'twelve,' 'this afternoon', 'the Civil War'. Thus, we use the simple past.

Hi ykaiim,
In the first problem, 'have been' isn't a matter of continuing vs. not continuing; it's a matter of specified time versus unspecified time. In the first sentence, we are given a time cue to when they were motivated: the change was "recent," at the time of the amendments. Because we know when the even happens, even if not the exact time, the simple past is correct
In the second, we have no time cues whatsoever; we don't know if the earthquakes happened yesterday or 100 million years ago. When an English sentences discusses events in the past without specifying the time frame, the present perfect 'have/has [participle]' tense is correct.
