Exactly six different essays will appear in a coming issue of a magazine. Three of the essays- G, I, and Jare by the writer K, and the other three essays-M, N, and P-are by the writer Y. Each essay will appear exactly once in the issue, and an essay must appear on each of the pages 3, 6, 9, 12, 15, and 18. The order in which the essays appear in the issue will be governed by the following conditions: The essays on pages 3, 9, and 15 must all be by the same writer. I must precede P. M must precede J. J could appear on any of the following pages EXCEPT

A. 3

B. 6

C. 9

Explanation: The pages are 3, 6, 9, 12, 15, 18. Essays by K: G, I, J. Essays by Y: M, N, P. Rule (3) is **M must precede J** (\(M < J\)). J is by writer K. M is by writer Y. If J were on **page 3**, it would be the first essay. Since M must precede J, M would have to be on a page *before* page 3, which is impossible (page 3 is the first page). Therefore, J cannot appear on page 3. All other options (6, 9, 12, 15) are later pages and could accommodate M before J.
