Answer to Question 1

C
There is no center choice when an even number of response alternatives are provided. If there is no center, then participants will be forced to make a choice that is NOT in the center position. If the directions are clear and the scale (pole) ends are mutually exclusive and opposite, participants won't be confused by the way in which the responses are gathered. Presenting an even number of choices is not restricted to ratio scales.

Answer to Question 2

B
The interval scale is the lowest scale of measurement that has equal intervals. It has an arbitrary zero point (one that does not mean the absence of the variable being measured).
