which one would be correct: "they" or "those" and why?
thanks in advance[/i]
great question. here is the answer.
"they"is used when latter subject is the same as previous subject. "they" is COREFERENT
"those" is used when the latter subject is different from previous subject."those" is SUBTITUTE
for example.
the persons learned gmat; they learned gmat very hard----the same persons, one group
the persons of the first batch learned gmat; those of the second batch learned gmat very hard---2 different groups
you can read grammar books for COREFERENCE AND SUBSTITUTION.But I think, do not read much. remember my explanation is enough for gmat
in OG10, the question " earthquark..." mentions this problem but the OG explanation is not clear.
