Question

multiple-choice question
which of these is not functioning?
a pepsi button that gives me pepsi, a mountain dew that gives me mountain dew. a diet pepsi that gives me diet pepsi.
a pepsi button that sometimes gives mountain dew and sometimes spits out pepsi.
three pepsi buttons that all give me pepsi.

Explanation:

To determine which is not functioning, we analyze the purpose of a "Pepsi button" (to dispense Pepsi). The first option has buttons dispensing their respective drinks (functioning as intended). The third option has three Pepsi buttons all dispensing Pepsi (consistent, so functioning). The second option: a Pepsi button sometimes gives Mountain Dew and sometimes Pepsi – it doesn’t consistently dispense what it’s supposed to (Pepsi), so it’s not functioning.

Answer:

B. A Pepsi button that sometimes gives Mountain Dew and sometimes spits out Pepsi.
