Hi Chen — we don’t have enough information to infer that “those” refers specifically to students — one small hint is that “student” is singular and “those” is plural — in order for the those to refer to students here, we would need some additional text such as “and of those students…” or “only those students who…” —
HTH and take care — Mike
