Directions: The following passage is followed by a question with five options. Choose the best option.

PUBLIC ANNOUNCEMENT: When you enroll with Golden Careers Business Institute (GCBI), you will have access to our placement counseling service. Last year, 92% of our graduates who asked us to help them find jobs, found them. So go to GCBI for your future!

Which of the following would be appropriate questions to ask in order to determine the value of the preceding claim?

I. How many of your graduates asked GCBI for assistance? II. How many people graduated from GCBI last year? III. Did those who asked for jobs find ones in the areas for which they were trained? IV. Was GCBI responsible for finding the jobs or did the graduates find them independently?

This advertisement is simply rife with ambiguity. The wording obviously seeks to create the impression that GCBI found jobs for its many graduates and generally does a lot of good for them. But first we should ask how many graduates GCBI had - one, two, three, a dozen, or a hundred. If it had only twelve or so, finding them jobs might have been easy. So II is certainly something we need to know in order to assess the validity of the claim. Now, how many of those who graduated came in looking for help in finding a job? Maybe most people had jobs waiting for them (only a few needed help), in which case the job placement assistance of GCBI is not so impressive. Or perhaps the graduates were so disgusted they did not even seek assistance. So I is relevant. III is also important. Perhaps GCBI found them jobs sweeping streets - not in business. The ad does not say what jobs GCBI helped its people find. Finally, maybe the ad is truthful - GCBI graduates found jobs - but may be they did it on their own. So IV also is a question worth asking.
