Question

For a disjunction to be true ___________________________ the joined statements must be true.

Answer 1

it has something to do with 'or' right ?

Answer 2

For the disjunction p V q to be true, p can be true and q false, p can be false and q true, or both p and q can be true. A disjunction p V q will be false when both p and q are false.

I don't know what "fits" into the blank in the question, but I would guess that "either" of the joined statements must be true.
