Answer to Question 1

B

Answer to Question 2

Optimization is an extension of goal seeking and refers to a process where the user can change many variables to reach some maximum or minimum target, as long as the changes stay within the constraints the user identifies. Optimization is used in decision support in many settings in which the best solution must meet many constraints that are difficult to juggle. A publishing house, for instance, tries to optimize profit per published book deal, taking into account constraints such as printing costs, discounts, and advertising. The list grows ever longer and complex as the decision support tools try to balance many competing variables.

Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
