Number 28. Tino combines the three building blocks shown on the right. Which of the following constructions can you make? Pause if you want to try and solve it. Okay, so for this one you just have to try to imagine combining these and see which of the constructions you can make. And there's one thing you can do to help yourself, and that is to try to figure out where to put this block, because this is the only block that always has two levels, right? There's a top one over here and a bottom one. And even if you turn it or rotate it, no matter what you do, it's always going to have two levels. Well, this one can have one level, this one can have one level, or each of them could also have two levels. But this one always has two levels. So for example, that gets rid of option B right away, right? Because there's no second level, there's no block on top here. And so you basically just have to try for each of these blocks over here, see if you can make them. And ultimately what you'll find is that the only one that you can make is D. And we can do that by putting this block over here, right? We have it go like this, and it'll go like that. And then, for example, we can take this block and put it over here, right? We'll have it go like this, and it'll have these three over here. And then that leaves this part over here, which we can see is this sort of L-shaped block, which is this block over here. So if we combine these three blocks, we can get option D. So the correct answer is answer choice D.
