Answer

Brief Explanations:

A simple machine is a device that makes work easier by changing the magnitude or direction of a force. In this case, using a simple machine (like an inclined plane which stairs can be related to conceptually) helps in reducing the force required (makes the work easier) rather than necessarily keeping the box safer (safety isn't the main functional purpose here compared to work - ease), reducing time (time isn't the key aspect simple machines are about in basic functionality), or reducing distance (work (W = F\times d), simple machines trade - off force and distance, they don't reduce distance to do the work).

Answer:

A simple machine will make the work easier.
