The more difficult questions in this Concept Builder include a variety of distracting elements. The trick is to use the same type of analytical and principled-thinking that you used on the easier questions.
Here the 5.0-kg box is at rest, but wedged between two objects - a finger on the left side and a scale on the right side. You want to know how the scale reading - that is, the normal force acting between the box and the scale - compares to the weight of the 5.0-kg box. To do so, consider the forces acting upon the box. Your analysis will have to include some attention to direction of forces.
There are two obvious contact forces - the normal force (leftwards) from the scale and the normal force pushing (rightwards) from the finger. And then there is force of gravity (the Earth pulling the box downard). When analyzing the horizontal forces, one must conclude that they are balanced since the box is at rest. So the normal force from the balance (directed leftwards) is balanced by the finger pushing the box to the right. But there is no way to know the value of this rightward force. So from this type of analysis or reasoning, you should be able to answer the question.
Wait! One More Thing
Now if you're thinking then you might be a bit disturbed at this point (but never let that discourage you from thinking ... let it encourage you into deeper thinking). What happens with the vertical forces. If there is a force of gravity acting downwards then there must be some force acting upwards on the box. Where does this force come from? Answer: friction. When two surfaces are pressed together (i.e. experience a normal force), then any motion or would-be motion of the two surfaces across each other results in a friction force. In this case, there is an upward frictional force between the box's surface and the surface of the scale and of the finger-tip.
