User: One of the disadvantages of using truth tables is (Points : 1) it is difficult to keep the lines straight T's are easy to confuse with F's. they grow exponentially and become too large for complex arguments. they cannot distinguish strong inductive arguments from weak inductive arguments.

Weegy: They grow exponentially and become too large for complex arguments.
