Six months ago, the developers of a fitness application introduced a "daily streak" feature. This feature awards a digital badge for every consecutive day a user logs a workout of at least 30 minutes. Among users who have been consistently active on the application since before the update, the vast majority report being highly motivated by the new feature and have significantly increased the number of days per week they exercise. Surprisingly, however, the average total number of minutes these users spend exercising each week has decreased over the last six months.
Which one of the following, if true, most helps to resolve the apparent discrepancy?
- ABefore the daily streak feature was introduced, users frequently forgot to log their workouts in the application, resulting in significant amounts of unrecorded exercise time.
- BA substantial portion of the individuals who joined the application after the update found the 30-minute daily requirement too demanding and quickly deleted their accounts.
- CUsers who engage in shorter workouts tend to experience less muscle fatigue, which physically allows them to exercise on consecutive days.
- DThe digital badges awarded by the application only track the occurrence of a 30-minute workout and offer no additional incentives for extending a session beyond that minimum duration.
- Prior to the update, these users typically exercised only two or three days a week, but their individual workout sessions almost always lasted for an hour or more.Cevap
Cevap
The statement that users previously exercised fewer days per week but for much longer individual durations.
The apparent discrepancy is that users are exercising on more days per week, yet their total weekly exercise time has decreased. The correct answer resolves this by showing that the structure of their workouts changed drastically: before the update, users exercised less frequently but for much longer durations. When they shifted to more frequent but shorter workouts to maintain their streaks, the shorter duration of each session caused the overall weekly total to drop, despite the increase in workout days.
