Answer 1

I think it is (a) because there are usually no warnings before a cave-in

Answer 2

Both statements about excavation accidents are true.

Explanation

Statistics have shown that almost all excavation accidents occur in trenches that are 5 to 15 feet deep. They mostly occur as a result of a cave in and collapsing of excavation walls. There are usually no warnings before a cave-in. When the earth’s material is cut or depressed by an excavating machine, a cave in can occurs resulting to injury and death.
