as has too many usages to list here.
Generally,
just as means IN THE SAME WAY AS.
SC99 in the OG11:
Just as reading Samuel Pepy's diary gives a student a sense of the seventeenth century, so listening to Jane Freed's Guileless Child Narrator takes the operagoer inside turn-of-the century Vienna.
Conveyed meaning:
Listening takes the operagoer inside turn-of-the century Vienna IN THE SAME WAY AS reading gives a student a sense of the seventeenth century.
From GMATPrep:
Airline executives are convinced that, just as one-third of bank customers still prefer human tellers to automatic teller machines, many travelers will still use travel agents.
Conveyed meaning:
Many travelers will still use travel agents IN THE SAME WAY AS one-third of bank customers still prefer human tellers.
2) How a pronoun 'it' refer to a gerund? Should not 'it' refer to clear noun?
A gerund is a VERBing that serves a NOUN.
A pronoun may serve to refer to a gerund, just as a pronoun may serve to refer to any noun.
Conveyed meaning:
A pronoun may serve to refer to a gerund IN THE SAME WAY AS as a pronoun may serve to refer to any noun.
Also 'it' refers to 'owning and living, Should not 'they' used instead of 'it' as we talk about 2 things 'Owning and living?so we should use 'they' for plural.
Generally, a compound subject is composed of two nouns connected by
and:
X AND Y.
In the vast majority of cases, a compound subject will be considered PLURAL and will take a PLURAL VERB.
in some cases, however, a compound subject will be considered SINGULAR and will take a SINGULAR VERB.
In the SC above, the non-underlined portion reads as follows:
Owning and living in a free-standing house IS still a goal of a majority of young adults.
Here, the verb in red is SINGULAR, indicating that the subject --
owning and living in a free-standing house -- is to be considered SINGULAR.
Note:
On the GMAT, a compound subject should be considered singular ONLY IF THE NON-UNDERLINED PORTION makes the intention clear.
