337. Idioglossia is a phenomenon, incompletely understood at best, where two persons develop a unique and private language with highly original vocabulary and syntax.
(A) where two persons develop a unique and private language with
(B) when two persons develop a unique and private language having
(C) in which two persons have unique and private language development with
(D) having two persons who develop a unique and private language that has
(E) in which two persons develop a unique and private language with

E? I see a grammatical error it shoudl be "an" unique, and also shoudl be people the plural and not persons?

[Stacey Koprince]

In American English, it is actually "a unique..." because the "u" sound here is a hard u. And you can use either people or persons - persons is a bit old-fashioned but not incorrect. (And, actually, the test often likes to use old-fashioned-but-correct stuff to trip us up.)

it is always an honour to have an element with a unit value.

sorry sentence makes no sense at all but it teaches you a lot.
