Quote:
E) The company's relocation will tend to increase the proportion of jobs in Metroburg that are in the public sector, unless it results in a contraction of the public-sector payroll.
(E) says that the company's relocation will tend to increase the proportion of public-sector jobs in Metroburg, unless that same relocation also results in a contraction of the public-sector payroll.
We know that the company is "one of Metroburg's largest private-sector employers." It logically follows that if one of Metroburg's largest private-sector employers relocates all of its employees to a location outside of Metroburg, then the result will tend to be a lower proportion of private-sector jobs (and a higher proportion of public-sector jobs) in Metroburg)...
...
unless that same move results in a contraction of the public-sector payroll.
This second part of choice (E)
simply says that we won't see a tendency towards increase in the proportion of public-sector jobs if there's an accompanying contraction of public-sector payroll. In other words, a contraction may reduce the tendency of an increase. We can't tell from the passage whether a contraction in public-sector payroll is likely to happen or how it could happen, but we don't need to know that to accept the logic of this statement.
This is why choice (E) can be more properly be concluded than any other choice available.
I hope that helps!
Hi
GMATNinjaI have a query regarding the interpretation of the conditional logic of ‘unless’
A unless B
Implies if not B then A or the contrapositive if not A then B
Your explanation for ‘ The company's relocation will tend to increase the proportion of jobs in Metroburg that are in the public sector, unless it results in a contraction of the public-sector payroll’ is ‘we won't see a tendency towards increase in the proportion of public-sector jobs if there's an accompanying contraction of public-sector payroll’
So for A unless B you are implying that if B then not A ….I believe that’s incorrect.
Would love some clarity on this
Also it would be great if you could let me know why interpreting ‘if B then not A’ from ‘A unless B’ is not logically correct
