question 19
for maximum efficiency, a good rule of thumb in an or decision is to ____.
first ask the question that is more likely to be true
rewrite it as an and decision and ask the question more likely to be true
rewrite it as an and decision and ask the question more likely to be false
first ask the question that is more likely to be false

Explanation:

1. In programming, the case structure (like in switch - case in many languages) is used when a variable has multiple distinct values each needing a different action.
2. In an OR decision, for maximum efficiency, it is better to first ask the question that is more likely to be true. If it is true, we can avoid evaluating the other conditions in the OR operation.

Answer:

1. A. case
2. A. first ask the question that is more likely to be true
