We have the 2 statements p and q.
We can see them both in the sentence connected by the word or:
The forest is dark or the moon is full.
When 2 statements are connected by the word or, we call it a disjunction.
We represent the or symbolically with ∨. Then, a symbolic expression for the sentence is p∨q.
To build the truth table, we need to consider that for a disjunction to be false, both statements in the disjunction should be false. Then, for the truth table:
p q p∨q
T T T
T F T
F T T
F F F
With this, the correct answer is option A.
