How many types of technical issues are listed?

• A. 3
• B. 4
• C. 5
• D. 6

Answer: (B)

Counting distinct categories is what this item tests. Each type is described as its own category with its own defining features, so you determine the count by grouping items that share the same defining trait and not double-counting subpoints. In the material for this question, there are four distinct categories of technical issues described, so the total number of types is four. To check, scan for the unique trait that defines each category and confirm that every listed item fits one of the four categories without creating a new category. If you end up with three, you’ve merged two into one category; if you feel you need more than four, you’re splitting a category that’s actually the same. Four is the correct count.
