In a tandem milking parlor, which is true?

• A. Cows stand nose-to-tail inside individual stalls.
• B. Cows enter in groups and leave in groups.
• C. Cows ride a rotating platform.
• D. Cows stand parallel to milkers.

Answer: (A)

In this design, the arrangement being tested is how cows are positioned in a tandem milking parlor. A tandem parlor uses a single file of cows, each cow in its own stall along the line, with the cows positioned nose-to-tail inside those stalls. This setup supports milking one cow after the next as the milker moves along the line, attaching the milking unit to each cow in turn. Rotary parlors involve a rotating platform where cows stand while being milked as the platform turns, so that describes a different system. Entering and leaving in groups is more typical of parlor designs that handle cows in batches, not a strict single-file tandem. Standing parallel to the milkers would imply a side-by-side arrangement facing the milker, which isn’t how tandem parlors are arranged.
