FINAL REPORT
I opened task.html from Downloads in the file manager and chose Chrome when prompted. The page was a color challenge: the three colors at the top were orange, navy blue and purple. I selected those three swatches from the palette and drew a stroke with each on the canvas, then tapped Submit. The page confirmed the submission with "Success!".
