Joshua: I have spent a lot of time in Europe on tour with the men’s choir I am a part of. Having stayed at hotels throughout Scandinavia, I have noticed that there is a large discrepancy in the quality of the woodwork between hotels that were built before 1950 and those built after. It’s clear that carpenters who worked on hotels built before 1950 were far more skilled and took greater pride in their work than carpenters who worked on hotels built after 1950.Which of the following, if true, most seriously weakens Joshua’s argument?

About a third of the questions that appear in the GMAT verbal section are critical reasoning questions.Typical questions that appear in critical reasoning (GMAT CR) include strengthening an argument, weakening an argument, identifying the assumption of an argument, mimic the reasoning, identify the reasoning, conclusion, inference, bold faced statements, and evaluating an argument.

Each of the critical reasoning questions is based on a short argument, a set of statements, or a plan of action.
