From Karijini , it 's 200 kms on a dirt road , through the deserted town of Wittenoom . We had all the windows up for most of the trip not only as a precaution against asbestosis but just to keep out the clouds of red dust that we were drawing behind . At one stage we had a quick rest stop and happened to look under the van . Dragging along the ground beneath it was most of the electrical circuitry , slowly being worn away on the rocks and dirt .

Question: What will the occupants of the van do now ?
Answer: The people will drive a little more slowly to avoid the rocks .They will fix the electrical components so they do not hang down too low the ground .None of the above choices .They will clean the van and get rid of all the red dust and dirt from it .
