The percentage of households with an annual income of more than $40,000 is higher in Merton County than in any other county. However, the percentage of households with an annual income of $60,000 or more is highest in Sommer County.
If the statements above are true, which of the following can properly be concluded on the basis of them?
When we see the language "properly be concluded" in the stem, the correct answer will be clearly true given what the passage says, rather than just likely to be true.
A. No household in Merton County has an annual income of $60,000 or more.
There's no support for some kind of ceiling on incomes in Merton county.
Eliminate.
B. Some households in Merton County have an annual income between $40,000 and $60,000.
This choice is interesting.
If The percentage of households with an annual income of more than $40,000 is highest in Merton County but the percentage of households with an annual income of $60,000 or more is highest in Sommer County, then not everyone in Merton with an income above $40,000, has an income above $60,000.
After all, if they all did, then Merton County would have the highest percentage above $60,000.
So, there must be some people in Merton with incomes between $40,000 and $60,000.
Keep.
C. The number of households with an annual income of more than $40,000 is greater in Merton than in Sommer County.
There's no information at all on "the number" of households, only on percentages.
Eliminate.
D. Average annual household income is higher in Sommer than in Merton County.
This could be correct, but their could be a few people in Merton County with super high incomes who pull the average above the Sommer county average.
Eliminate.
E. The percentage of households with an annual income of $80,000 is higher in Sommer than in Merton County.
All the passage indicates is the percentages of households with incomes above $40,000 and $60,000. Anything could be going on above $80,000.
Eliminate.
Correct answer: B
