<h3 style="text-align: left;">Complete the quiz</h3>
<p style="text-align: left;">This section contains the Session Quiz. All quizzes, surveys, and knowledge checks count towards your progress for a course certificate.</p>
<h3 style="text-align: left;">Instructions</h3>
<p style="text-align: left;">In your copy of the Crop_health notebook:</p>
<ul style="text-align: left;">
<li>change the latitude parameter to -0.18990</li>
<li>change the longitude parameter to 34.81347.</li>
</ul>
<p style="text-align: left;">This corresponds to fields south of Kisumu, Kenya.</p>
<p style="text-align: left;">Run the notebook to load the data and the crop health app. In the app, draw polygons matching those in the image. You may need to use the zoom buttons on the map to see the whole loaded area (red square). </p>

<p style="text-align: left;">To get the same colours, draw the blue (left-most) polygon first, then draw the orange (right-most) polygon second. Then view the plot of Normalised Difference Vegetation Index (NDVI).</p>
