What is a paradox?
a. two sentences that contain the same main idea
b. a statement that seems to say two opposite things but that may be true
c. an event in literature that creates suspense
d. the tone of a piece of literature

♥Lets look at the definition of Paradox.
♥This is a statement that leads to a contradictory situation in which something seems both true and false.
After we read and conclude with that information there, we know our answer will be A.
As you can see in the definition it says "in which something seems both true and false."
So basicly containing the same idea.
♥Leaving us with A.
♥Hope this helps!♥
