. When attempting to minimize memory usage, the most efficient way to do group processing when using the MEANS procedure is to use: A. the BY statement. B. GROUPBY with the NOTSORTED specification. C. the CLASS statement. D. multiple WHERE statements.

A. the BY statement.

Explanation:

The BY statement aids the procedure MEANS to develop the tree for the current BY group only, thereby analyze the stats, and clean the tree prior to the start and development of the next BY group.

However, without the BY statement, procedure MEANS develops its AVL tree for both the whole file and all sector estimates crossings established in CLASS.

Hence, in this case, the correct answer is the BY Statement.

it would be a. excessive network collisions or d. slow connectivity between devices those would be my answer.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
