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 .
What may be the reason for the rain proofing material ?
Pick the best answer from the following options:
- 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 .


They needed to protect their construction work from rain .
