Airline Representative: The percentage of flight delays caused by airline error decreased significantly this year. This indicates that airlines listened to complaints about preventable errors and addressed the problems. Although delays caused by weather and other uncontrollable factors will always be part of travel, preventable delays are clearly decreasing.


Which of the following most clearly points to a logical flaw in the representative's reasoning?



A. Airlines may be motivated by financial concerns to underreport the percentage of flight delays caused by airline error.


B. The delays caused by uncontrollable factors could have led to an increase in complaints to airlines.


C. Complaints may not be the most reliable measure of how many errors occurred in a given year.


D. Delays caused by weather and other uncontrollable factors could have increased dramatically during the year under discussion.


E. Airline customers might not believe that particular delays were caused by uncontrollable factors rather than airline error.


The Airline rep says-


The percentage of flight delays caused by airline errors decreased significantly this year.

This indicates that airlines listened to complaints about preventable errors and addressed the problems

Although delays caused by weather and other uncontrollable factors will always be part of travel,

preventable delays are clearly decreasing- Opinion/ conclusion


We need to find an option that points to a logical flaw in the representative's reasoning.


A. Airlines may be motivated by financial concerns to underreport the percentage of flight delays caused by airline error.


Financial concerns are out of the scope of the argument. It does not point to a flaw in the representative’s reasoning. Eliminate.


B. The delays caused by uncontrollable factors could have led to an increase in complaints to airlines.


delays caused by uncontrollable factors could have led to an increase in complaints to airlines- Talks about the increase in overall complaints. 

We still don’t know the proportion of such delays and complaints.

Remember the airline representative is arguing that preventable delays are clearly decreasing because the percentage of flight delays caused by airline error decreased significantly this year.

Eliminate.


C. Complaints may not be the most reliable measure of how many errors occurred in a given year.

Out of scope. Eliminate



D. Delays caused by weather and other uncontrollable factors could have increased dramatically during the year under discussion.


Correct. D addresses the problem that option B fails to address.


Delays caused by weather and other uncontrollable factors could have increased dramatically during the year under discussion.


Delays caused by- 

preventable factors- X

weather and other uncontrollable factors-Y


The airline representative is arguing that Preventable delays are clearly decreasing because- the percentage of X has significantly decreased this year.

Option D says that Y increased dramatically this year. This could have been the reason why the percentage of X has decreased significantly this year.



E. Airline customers might not believe that particular delays were caused by uncontrollable factors rather than airline error.

We don’t have to bother about what customers believe. Eliminate
