(d) —------ example, the book and the table are (e) —------ the kitchen. This ensures you a basic understanding.  If we add another preposition, it makes it even clearer. This book is (f) —------ top of the table (g) —------ the kitchen. We have a clear picture (h)  —------ our mind (i) —------ their relationship of those two objects and their relationship (j) -—---- each other.
