Can you please explain?

Hi @Jaimee-Salgado, thanks for your post. As always, let's start with the stimulus. This one presents a set of facts, rather than an argument - there is no conclusion to speak of. The question stem asks you to select the answer that is textually supported by the information in the stimulus (thus, this is a Must Be True question). Answer choice (E) is textually supported by the first sentence of the stimulus. That sentence tells you that individually-tailored work schedules do "not typically increase managers' job satisfaction or their efficiency." Because of this, (E) must be true: "The typical benefits of flexible-schedule policies *cannot* be reliably inferred from observations of the effects of such policies on managers." Answer choice (B) is incorrect because the stimulus tells you that the benefits of flexible-schedule policies "dissipate somewhat over time," which means it is not clear that such policies "should be expected to improve the morale of some but not the overall morale." We just don't know enough to comment on "overall morale," especially given the fact that certain benefits of flexible-schedule policies "dissipate somewhat over time." Hope this helps! Please let us know if you have any additional questions.
