Here is a question for the GMAT exam:
Having been named for a mythological nymph who cared for the infant Jupiter, the asteroid named Ida in the middle of the belt of asteroids that orbit the Sun between Mars and Jupiter, was discovered in 1884
For those of you unfamiliar with the test, basically you are given a short statement with some underlined part. You have to decide if you keep the underlined part as is (option A) or if you substitute it with one out of 4 options (options B,C,D,E).
Here the whole statement is underlined
Now in the solution, it says that the "keep it" option (option A) is wrong because
Opening with a past perfect passive verb, Having been named, this version of the sentene illogically suggests that being named for a mythological nymph preceded the discovery of Ida
My question is: why "Having been named" is a past perfect passive? The past perfect (active) should be formed by: Subject + had + past participle And thus the passive one: Subject + had + been + past participle
So what tense is Having been named really if it is not a past perfect passive?
