Announcing that one of its key successes had been the recent well-received beta launch, the Internet start-up claimed it would introduce several new products to the web community during the next quarter.
A: its key successes had been the recent
B: its key successes has been the recently
C: its key successes is the recently
D: their key successes is the recent
E: their key successes had been the recent
between past perfect and present perfect , what should be preferred here ?
Well this answer would have been (A)
even if we had this choice :
its key successes had been the recently
Adjective can modify Noun
Adverb can modify Verb
Here well-received beta launch
is a NOUN and not VERB, so you have to go with adjective :RECENT and not adverb : REECENTLY
Coming to the use of HAD BEEN, it is parallelism....
HAD BEEN is parallel to WOULD, so this would narrow down the choices to A, E...After that ITS is the correct usage so go for A...
