A new smartphone app that encourages healthy eating by tracking daily nutrient intake has reported significant user weight loss after six months of use. The developers claim that the app’s reminder system, which prompts users to record their meals and snacks, is the primary reason for this weight loss success.
In evaluating the developers' argument, it would be most important to determine which of the following?
(A) Whether users of the app also engage in regular physical exercise apart from using the app
(B) Whether other similar nutritional tracking apps also show similar results in terms of user weight loss
(C) Whether the users had tried other diet methods before using the app and had not seen similar weight loss results
(D) Whether the reminders from the app are more effective at altering eating habits compared to other features of the app
(E) Whether users continue to lose weight or maintain weight loss after the initial six months of using the app

GMAT Club Official Explanation:
Correct Answer: D. Whether the reminders from the app are more effective at altering eating habits compared to other features of the app.
The argument claims that the reminder system in the app is what drives the weight loss - not other aspect of the app. This choice highlights that the reminder system is the primary factor driving user weight loss by questioning if this feature specifically (versus other app features or external factors) is the most influential in changing eating habits.
A. Whether users of the app also engage in regular physical exercise apart from using the app.
Trap answer. Knowing this information would help us to know only 1 external factor but there could be more than 1. What if app users engage in other physical activity or what if they don't but they instead do fasting or what if they eat smaller meals or take medication? This choice does not isolate those options and so we still would struggle to determine whether it is the app itself, reminder system, OR external aspects which resulted in weight loss. As the result, we cannot evaluate the effectiveness of the app's reminder system itself and thus this choice would not help us in evaluating the developer’s argument that reminders are the key feature. Eliminate.
B. Whether other similar nutritional tracking apps also show similar results in terms of user weight loss
This choice compares the app to others but does not specifically address whether the reminder system within this particular app is the key to its success.This could help evaluate the app’s performance vs. other apps, but what if other apps also have similar reminder system? We don’t know anything about other apps and how they compare. We do not know that the reminder system is exclusive or unique to this app. Eliminate.
C. Whether the users had tried other diet methods before using the app and had not seen similar weight loss results
This answer choice might indicate the app’s overall effectiveness but doesn’t focus on the reminder system’s impact compared to other app features or external interventions. For example, app users may have used another weight-loss method, and indeed have seen results after using the app, but we would not know if the reminders features of the app were responsible for the weight loss, only that the app made a difference, and that’s not specific enough. Eliminate.
E. Whether users continue to lose weight or maintain weight loss after the initial six months of using the app
This answer choice does not focus on evaluating the specific claim about the reminder system’s role during the initial period, only long-term benefits which are not relevant for the argument. Eliminate.
