This CR question focuses on a common flaw in arguments involving percentages and populations: specifically, the difference between "all graduates" and "all students."
The Argument StructureEvidence: In the last two quarters, every graduate of the bootcamp landed a job within 90 days.
Conclusion: If you enroll in the bootcamp, you can count on launching a career within 4 months (1 month of study + 90 days of searching).
(A) Graduates of Code to Career with equivalent coding skills often secure jobs within varying timeframes.This is
incorrect because it
does not challenge the advertisement's claim. As long as those "varying timeframes" still fall within the promised 90-day window, the advertisement's track record remains technically accurate.
(B) Among the graduates who secured jobs, most received their offers in the final month of the 90-day period rather than immediately after graduation.This is
incorrect because it actually
supports the timeline mentioned in the advertisement. The ad claims a career launch within 90 days of graduation; whether that happens on Day 1 or Day 89, the promise of "within 90 days" is still being met.
(C) A considerable percentage of students who initially enrolled in Code to Career did not complete the program or submit a capstone project.This
reveals a major weakness by exposing a "survivorship bias." The advertisement promises that if you enroll, you will get a job. However, the evidence only looks at graduates. If a large portion of students fail or drop out before graduating, then simply enrolling does not guarantee success. The conclusion is weak because it ignores the high risk of not finishing the program at all.
(D) Some rival coding bootcamps offer job placement services that TechPro Academy does not provide.This is
incorrect because the
performance of competitors is irrelevant to the internal logic of TechPro's argument. Even if other schools have better services, it doesn't prove that TechPro’s specific claim about its own graduates is weak or false.
(E) TechPro Academy introduced the Code to Career bootcamp just six months ago.This is
incorrect. While a short history might make a track record less impressive, the advertisement already admits the data comes from the "last two quarters" (which is six months). This choice
confirms the timeline the ad already stated rather than revealing a logical weakness in how the conclusion was reached.
