Directions: Most questions in the Physical Sciences test are organized into groups, each preceded by a descriptive passage. After studying the passage, select the one best answer to each question in the group. Some questions are not based on a descriptive passage and are also independent of each other. You must also select the one best answer to these questions. If you are not certain of an answer, eliminate the alternatives that you know to be incorrect and then select an answer from the remaining alternatives. (On this web exam: if you leave an answer blank, I'll give you ¼ point.) Indicate your answer by clicking on the appropriate button on this sheet. A periodic table is provided for your use. You may consult it whenever you wish.
