Is it C? 2 actions are shown in past perfect which is correct and the later action is shown in past which is also correct.

[gmatmachoman]

IMO B

1. Proper usage of past perfect tense (had finished ....relaxed)

2.Parallelism is maintained.

[hardik.jadeja]

IMO C

A) maestro relaxed - simple past , concert having been finished --not past perfect -- Hence wrong

B) he has an ambigous reference. Also usage of because twice is redundance.

D) "concert had finished " -- what did concert finish ? Its not something that concert had finished But instead its concert that had been finished..hope u got it. Also "maestro had relaxed" --usage of past perfect is wrong here

E) Option A issue + had relaxed is wrong...

Hope that helps.

[paes]

Yes, OA is C.
But I selected B over C because of following reasons.

1.
C says : Since the concert had been finished ...
from here it is not clear that 'who finished the concert'
while from B, clearly : the maestro had finished the concert

2. The usage of 'he' is clear in B. He can not refer to audience, it can refer only to maestro .
Also pronoun ambiguity is not a must rule.

3. Because the maestro ..... and because the audience : making parallelism
4. because is generally preferred to since.

Please clarify what's wrong here.

[vscid]

in B the referent for 'he' is ambiguous.

[paes]

in B the referent for 'he' is ambiguous.

how 'he' is ambiguous ?

The usage of 'he' is clear in B. 'He' can not refer to audience, it can refer only to maestro .
Also pronoun ambiguity is not a must rule.

The concert having been finished and the audience having filtered out, the maestro relaxed in the dressing room with the impresario.

A. The concert having been finished and the audience havingfiltered out, the maestro relaxed in the dressing room with the impresario. - having indicates present perfect tense, however the action is already over, i.e. concert is already finished and the audience has already filtered out. therefore we cannot use present perfect tense here.

B. Because the maestro had finished the concert and because the audience had been filtered out, he relaxed in the dressing room with the impresario. - He/She should refer to a noun on GMAT

C. Since the concert had been finished and the audience had filtered out, the maestro relaxed in the dressing room with the impresario.

D. Since the concert had finished and the audience had filtered out, the maestro had relaxed in the dressing room with the impresario. - to use had, i.e. past perfect tense, there should be two completed actions, one having being completed before the other. Therefore we cannot use the third had here

E. The concert having been finished and the audience having filtered out, the maestro had relaxed in the dressing room with the impresario. - Same as A

Therefore, Answer C

In the question it was not indubitably asserted that the maestro finished the concert. And if this is not so established I believe it is better to go for a passive as the doer in the passive is not emphasized.

This leaves us with A,C and E.

E - tense error. And C is preferable to A because of the right usage and concision.
So My pick C.

Please correct me if I'm wrong.

[martin.jonson007]

IMO C

but 1 doubt ->

C. Since the concert had been finished and the audience had filtered out, the maestro relaxed in the dressing room with the impresario.

WHY NOT BOTH HAD BEEN IN PLACE OF ONE 'HAD BEEN' AND ONE 'HAD' ?

[gmatmachoman]

IMO C

but 1 doubt ->

C. Since the concert had been finished and the audience had filtered out, the maestro relaxed in the dressing room with the impresario.

WHY NOT BOTH HAD BEEN IN PLACE OF ONE 'HAD BEEN' AND ONE 'HAD' ?

Yeah well noted.. Moreover my doubt is" Because" is far better than "since". Guys plz hep me out

Mothit is right . B has pronoun error and HE although referring to MAESTRO , MAESTRO is not a noun here its used as an ADJECTIVE for a person who plays music and hence use of pronoun to refer to an ADJECTIVE is not proper .

'had been finished' is the past perfect passive voice form of 'had finished'. It is an action completed by the maestro.
'had filtered' is the action completed by the audience. This is in the active voice. Hence no 'been' here.

Rockey,
maestro is a noun not an adjective.
