Precision is defined as the closeness of two or more measurements to each other.This is how much close are the series of measurements of a same object to each other.
For example : If we measure volume of water in flask which comes out to be 2 mL and again on measuring for the number of times we get same value of 2 mL. Hence, this measurement will said to be precise.
A scale measures weight to the nearest 0.5 lb.So, from the given options the measurement which is appropriate to the given precision scale is 140.5 lbs.

Answer: C. 31
Explanation:
Set A contains [50, 51, 52, … , 99, 100]. Set B contains [70, 71, 72, … , 136, 137]
Notice that Set B and Set A have an overlap from 70 to 100. So that is 31 elements in total. Hence the set A intersect B is [70, 71, 72, … , 99, 100] which is 31 elements.
Cheers.
