The <b>Pool Questions Upload</b> utility can be used by Instructors and TAs to import <i>multiple choice</i>, <i>multiple answer correct</i>, <i>fill-in-the-blank</i>, <i>true/false</i> and <i>essay</i> questions from a plain text file into a Blackboard Question Pool. Five requirements must be met to ensure that you will succeed in building a Blackboard pool using your file of questions.
<ol>
<li>The questions and answers you plan to upload must be in plain text format. Any header lines should occur before the text containing the questions and answers.</li>
<li>All questions must occur before any of the answers. Each question should begin on a new line, and should start with the question number. Questions should be numbered sequentially using a number followed immediately by a space, a period, or enclosed in parentheses, i.e., 1 , 1., (1), 1), or (1 .</li>
<li>One or more correct answers should be provided for all questions (although blank answers may be provided for <i>essay</i> questions). Answers should be numbered sequentially, using the same scheme as used for the questions, and must occur after all the questions.
<li><i>Multiple choice</i> and <i>multiple answer correct</i> questions should consist of (i) the question number followed by (ii) a question stem beginning on the same line and (iii) two or more foils, with each foil beginning on a new line and prefixed by a unique letter, or Roman numeral, listed in alphabetic or numeric order, beginning at a (alphabetic) or i (Roman numeral), followed by a period, or enclosed in parentheses, i.e., a., (a), i., or (i) .</li>
<li>If <i>fill-in-the-blank</i> or <i>multiple answer</i> questions have more than one correct answer, each answer should appear in a comma-, tab-, space-, or new line-delimited list. </li>
</ol>
Five steps are involved in the import process.
<ol>
<li>Upload your text file to the server.</li>
<li>Provide information about the question format - i.e., question numbering style, and the number of blocks of questions of the same question type.</li>
<li>Provide information about the questions in each block, including question type, start and end question numbers for each block, and foil labelling style and answer format where required.</li>
<li>Choose an existing pool or create a new pool to receive the imported data.</li>
<li>Complete the import of questions to the selected pool.</li>
</ol>

The image above shows maps of six different areas of the seafloor adjacent to a spreading ridge. Each map includes the spreading ridge location (shown in yellow) and striping (in black and white) that depicts the pattern of magnetic reversals preserved in oceanic crust. A distance scale is provided at the top of the image, and a magnetic reversal time scale is provided at the bottom. Periods when the earth's magnetic field had the same polarity as today are black; periods when the field was reversed are white.<br/><br/>
Rank the spreading rates for each of the spreading ridges - (a) through (f) - with the fastest spreading ranked as 1, and the slowest spreading ranked as 6.<endouttext />
