A.) Why was it necessary to drill three small pipes into through the rockfall that trapped the men? Please elaborate on your answer.

The rockfall blocked the trapped space from being exposed to air and sunlight.

But much time was taken to get it away.

So drilling three pipes was temporarily required to provide oxygen and food     

before the rockfall was taken away.  ✔​
