2. This pie is fantastic! Can I have __________________ piece?
3. These pants don’t fit well. Let me try ____________________ ones.
The above questions are from gmat grammar book-exercise 4(using other, another)
so far what i learned from this exercise is
ANOTHER, OTHERS - It is used to non specific group.
THE OTHER-It is used for a specific group
can any body tell me how to recognise whether specific sentence refers to specific group or non specific group
