<p>Which of the following activities provides the best example of the way to multiply as discussed in the last paragraph? </p>

(B) Increasing the number of night guards in a museum
(C) Adding more buildings to a factory complex
(D) Keeping municipal offices open during the lunch hour
(E) Enforcing curfew laws in residential neighborhoods</p>
<p>This is the paragraph it is referring to:</p>
<p>Now, venturing into the night, we have the same motives as our predecessors who migrated geographically. The daytime is too crowded. Its carrying capacity is being strained, and still it does not yield all that the community wants. The chance to exploit facilities that are left idle also arouses our initiative to use more of the night. Using the same space more of the time is a way to multiply its capacity. Some people dislike the commotion of the day and crave the serenity of night. Others look to it to better themselves economically. It is no accident that personal motives for relief and opportunity are similar to the causes of expansion for the community as a whole. Those are the age-old forces behind all migrations.</p>
<p>I chose (D), the correct answer was (A). Both answers seem to be good examples of what the question is asking for; why is (D) incorrect?</p>
