[Guest]

The United States has experienced a big growth in job creation. This trend has continued for several years and will soon eliminate the problem of joblessness.
Which one of the answers below is an error in the reasoning that leads to the above prediction?

(A) It does not quote numbers showing how jobs are growing in comparison to the population.
(B) Some people will never have jobs because they lack the skills to hold a simple job.
(C) It fails to quote government reports comparing pay rates of new jobs to minimum wage.
(D) Some people will have to hold two or even three jobs to live at a minimum level.

I'm not totally convinced that this question is very worthwhile. An "error in reasoning" means just that: that the thinker has made some sort of logical misstep. But here, we instead have statements that might weaken the argument. An argument weakener is very different from an assumption/logical misstep; in fact, they can often be the exact opposite! (A weakener often disproves an assumption.)

Nevertheless, if we treat the question as a simple "Weaken the Conclusion" question, B is the best choice: if true, it shows that some people will never be able to hold a job; that certainly conflicts with the author's claim that joblessness will disappear entirely. The main flaw in this argument is that the acceleration of job creation will continue to the absolute, until there are no more people who do not have a job. Time is a tricky thing: even if a trend has been occurring, we cannot simply assume that it will always be the same.
