Test 6A 1 Logic Name:______________________________ Chapter 6 Test A Except for the truth table questions (which are double credit), each question is worth 2 points. Write your answer on the form provided. Erasure marks may cause the grading machine to mark your answer wrong. Select the correct translation for the following problems. 1.
