A page on disk initially contains 10 tuples. Instance P loads it, deletes 2 tuples, inserts 1 tuple, and writes the page. Instance Q then loads the page, deletes 3 tuples, but does not write. Finally, instance R independently loads the page from disk, inserts 2 tuples, and writes it. How many tuples will a new instance S read from disk?
