If is meaningful to say that Jimmy gets twice as much money as a weekly allowance than his little brother does, we know that allowance is being measured on this scale of measurement.
 
  a. nominal c. interval
  b. ratio d. ordinal

Question 2

Sizes of shoes do not have a true zero point, but have equal intervals separating the sizes from one another; therefore shoe sizes are measured on this scale of measurement.
 
  a. interval c. ratio
  b. nominal d. ordinal

Answer to Question 1

B
Ratios only make sense if the scale of measurement is a ratio scale.

Answer to Question 2

A
This is an example of an interval scale because it has equal intervals on the scale but has only an arbitrary zero point (size 0 is not the absence of a foot).
