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
This option is about physical exercise. While exercise can contribute to weight loss, the developers' argument focuses on the app's reminder system
Quote:
(B) Whether other similar nutritional tracking apps also show similar results in terms of user weight loss
This option compares the app to other similar apps. If other apps with similar reminder systems also show significant weight loss, it could support the argument that the reminder system is effective
Quote:
(C) Whether the users had tried other diet methods before using the app and had not seen similar weight loss results
This option looks at users' previous experiences with other diet methods. If users hadn't seen similar results with other methods, it strengthens the argument that the app's reminder system is effective
Quote:
(D) Whether the reminders from the app are more effective at altering eating habits compared to other features of the app
This option
directly addresses whether the reminders are the most effective feature of the app. If the reminders are indeed more effective than other features, it supports the developers' claim
Quote:
(E) Whether users continue to lose weight or maintain weight loss after the initial six months of using the app
This option looks at the long-term effectiveness of the app. While important, it doesn't directly address whether the reminder system is the primary reason for the initial weight loss
Option (D). This option directly addresses whether the reminders from the app are more effective at altering eating habits compared to other features of the app, which is central to the developers' claim
