Complete Question Explanation
(The complete setup for this game can be found here: viewtopic.php?t=8976)
The correct answer choice is (E)
This is the only Local question of the game. Given the information in the question stem, according to the second rule L must be advertised during week 4:
Since only G, K, and M are available to fill the second advertising slot in week 4, it can be inferred that either G, K, or M must be advertised with L. It follows that either answer choice (A), (D), or (E) is correct. Since G must be advertised along with J or O, G must be advertised in week 2 or 3, and thus G cannot be advertised with L. Consequently, answer choice (A) can be eliminated. Since L is the doubled product and K must then be advertised in week 1 or 2 only, it follows that K cannot be advertised with L, and answer choice (D) can be eliminated. Answer choice (E) is thereby proven correct by process of elimination.
Note how much easier this question is to solve with the knowledge that J must be advertised during week 2.
