The above represents a Venn diagram. The universal set 
is the set of all positive integers.
Let 
represent the set of multiples of 7; let 
represent all of the multiples of 11; let 
represent all of the multiples of 13. As you can see, the three sets divide the universal set into eight regions. Suppose each positive integer was placed in the correct region. Which of the following numbers would be in the same region as 2,431?
The above represents a Venn diagram. The universal set
Let
The region in which 2,431 appears depends on the sets of which 2,431 is an element, which in turn depends on which of 7, 11, and 13 divides it evenly:
2,431 is a multiple of 11 and 13, but not 7, so 2,431 is in 
and 
, but not 
. We look for a number among the choices that is in 
and 
, but not 
- that is, a number divisible by 11 and 13 but not 7.
, so 2,772 is divisible by 7. We can eliminate it.
, so 2,184 is divisible by 7. We can eliminate it.
, so 3,081 is not divisible by 11, and we can eliminate it.
, so 2,409 is not divisible by 13, and we can eliminate it.
However:
2,145 is divisible by 11 and 13 but not 7, so this is the correct choice.

Refer to the above graph, which shows the high and low temperatures for Kingdom City over a one-week period.
Which of the following temperatures occurred at least once on each of the seven days?
The graph is recreated in the figure below, with horizontal lines at the 57, 62, 67, and 72 degree levels.
It can be seen that of the four lines, only the 62 degree line falls between the high temperature and low temperature for each of the seven days. This is the correct choice.

Since we are dealing with the day after the last one shown, and we are comparing that day's high temperature to those of the previous five days, we only need to concern ourselves with the high temperatures for Tuesday through Saturday.
Examine the figure below, which shows the high temperature line for those five days.
For the high temperature for the next Sunday to be greater than exactly four of the five and less than the remaining one, the temperature must be strictly between the highest and second-highest high temperatures, which are seen to be 78 and 74 degrees, respectively. That is, if we let
