At eight am sharp , the crane arrived . While he set up the rig , I removed the extra tar paper and ice shield underlayments that had been wrapped over the peaks as a temporary rain proofing . Not that we have had any rain lately .

Question: What may be the reason for the rain proofing material ?
Answer: They wanted to keep the construction invisible .They wanted to hide the work they were doing .They needed to protect their construction work from rain .None of the above choices .
