Lesson 4/Practice Exercise
PRACTICE EXERCISE FOR LESSON 4
You have just finished reading the instructional material for Lesson 4. This lesson covered
supervision of chemical survey and biological sampling operations. It is now time to check your
understanding of the lesson. This is done by completing the practice exercise below. All of the
questions are multiple-choice and are intended to measure your understanding of the procedure used
in performing the task. There is only one correct answer to each question. Try to answer all of the
questions without referring to the lesson material.
When you have completed all of the questions, turn the page and check your answers against the
correct responses. Each correct response is referenced to specific portions of the lesson material so
that you can review any questions you have missed or do not understand. When you have
completed your review, continue to the next lesson.
