Part B
Enter your answers for this part in the special spaces that are numbered beginning with 101 in the space
labeled “Chemistry” on your answer sheet.
Directions: Each question below consists of two statements. Each statement in the left-hand column
is referred to as I, and each statement in the right-hand column as II. For each question, determine
whether I is true or false and whether II is true or false and fill in the corresponding T and F oval
spaces on your answer sheet. If, but only if, statement II is a correct explanation of statement I,
darken the oval space labeled CE.
