Statement: A construction worker was buried alive when
mud from a 20-ft high pit collapsed on him and four others. Assumption I: The other four people buried under the mud from the pit have been saved.

An assumption is something supposed or taken for granted. You have to consider the statement and the following assumptions and decide which of the assumptions is implicit in the statement.Solution
Because it is mentioned that one worker was buried alive we can assume that others are safe. There is nothing mentioned about the reason of this accident, hence only Assumption I is implied and correct answer is 1.
