In a world where mirrors do not reflect images but instead allow people to see through walls as if the wall were transparent, Kofi has placed a large mirror on his living room wall. On the other side of the wall is Lina, who is unaware of the mirror's magical properties and is trying to hide a birthday present for Kofi behind a bookshelf. If Kofi is looking directly at the mirror from a distance, will he be able to see the hidden present, and why?

Respond very briefly.
If Kofi is looking at the mirror and the mirror allows him to see through the wall as if it were transparent, he will see the room on the other side. Since the mirror replaces the wall with a view of what lies beyond, it would show him the room from the perspective of the wall where the mirror is hanging. Lina is trying to hide the present behind a bookshelf that is also on the other side of the wall. However, since the mirror gives Kofi the ability to see through the wall, the bookshelf would not provide concealment for the present in this scenario. Hence, Kofi would be able to see the hidden present behind the bookshelf as if the wall were not present, because the magical property of the mirror allows him to see through the wall.
