Final answer:
The truth table for Statement 2B has eight lines.
Step-by-step explanation:
The truth table for Statement 2B can be evaluated by considering the number of different combinations of truth values for the variables involved. In this case, we have three variables: N, S, and J. Each variable can take either a true (T) or false (F) value. Therefore, there are 2^3 = 8 possible combinations of truth values for the variables. Hence, the truth table for Statement 2B has eight lines.
