EXAMINATION I
Before beginning, check to be sure that this exam contains 7 pages (including front and back) numbered
consecutively, and that you have been provided with a clean Answer Sheet. Then immediately print your name
and UT-EID legibly at the top of this page. Also print and bubble in your name and your UT-EID (not your
social security number) on the front of the Answer Sheet in the spaces provided. The first 39 questions are
“multiple choice”, with only one correct answer. Mark the letter corresponding to the correct answer to each of
these questions in the appropriate location on the Answer Sheet, using a No. 2 pencil. Write answers to
Questions 40 – 42 directly on this exam, in the spaces provided with the questions. Write in complete sentences
if an explanation or a description is required. Print neatly if your handwriting is likely to be difficult to read.
Turn in both this exam and the Answer Sheet after checking to be sure that your name is clearly written in both
places and all questions have been answered in the appropriate locations. You must turn in your exam on or
before 9:55 a.m.
