Mgmat (Page-236) is giving following examples to modify a subgroup :

(i) This model explains all known subatomic particles, some of which were only recently discovered.

(ii) This model explains all known subatomic particles, some of them only recently discovered.

(iii) This model explains all known subatomic particles, some only recently discovered.


Can somebody explain me why 'were' is used for (i) not for (ii)/(iii)

"Which" is a relative pronoun, which generates a relative clause with its own verb (like in this very sentence). The others do not have a relative pronoun.

I think if we use were in ii and iii, we would have run on sentences, as the part after the comma would become independent clauses.
