The essay gives you an opportunity to show how effectively you can develop and express ideas. You should therefore take care to develop your point of view, present your ideas logically and clearly, and use language precisely. Your essay must be written on the lines provided on your answer sheet—you will receive no other paper on which to write. You will have enough space if you write on every line, avoid wide margins, and keep your handwriting to a reasonable size. Remember that people who are not familiar with your handwrit- ing will read what you write. Try to write or print so that what you are writing is legible to those readers. Important reminders: • A pencil is required for the essay. An essay written in ink will receive a score of zero. • Do not write your essay in your test book. You will receive credit only for what you write on your answer sheet. • An off-topic essay will receive a score of zero. You have twenty-five minutes to write an essay on the topic assigned below. Consider carefully the issue discussed in the following passage, then write an essay that answers the ques- tion posed in the assignment. We like to believe that physical phenomena, animals, people, and societies obey predictable rules, but such rules, even when carefully ascertained, have their limits. Every rule has its exceptions. Assignment: What is one particularly interesting “exception” to a rule? Write an essay in which you answer this question and discuss your point of view on this issue. Support your position logically with examples from literature, the arts, history, politics, science and technology, current events, or your experience or observation. If you finish before time is called, you may check your work on this section only. Do not turn to any other section in the test. CHAPTER 16 / PRACTICE TEST 4 775 2.

Directions: For this section, solve each problem and decide which is the best of the choices given. Fill in the corresponding circle on the answer sheet. You may use any available space for scratchwork. 1. The use of a calculator is permitted. 2. All numbers used are real numbers. 3. Figures that accompany problems in this test are intended to provide information useful in solv- ing the problems. They are drawn as accurately as possible EXCEPT when it is stated in a spe- cific problem that the figure is not drawn to scale. All figures lie in a plane unless otherwise indicated. 4. Unless otherwise specified, the domain of any function f is assumed to be the set of all real num- bers x for which f(x) is a real number. The number of degrees of arc in a circle is 360. The sum of the measures in degrees of the angles of a triangle is 180.
