Which statement about the main measurement numbers for smoothies and shakes is correct?

• A. They are 2, 4, 6, 8 and 8, 12, 16, 20
• B. They are 1, 2, 3, 4 and 4, 6, 9, 12
• C. They are 3, 5, 7, 9 and 9, 12, 15, 18
• D. They are 5, 10, 15, 20 and 20, 40, 60, 80

Answer: (B)

This question tests how two related measurement sets line up when you scale a smoothie or shake recipe. The pairing shown in the correct option uses a simple, practical pattern: a base sequence of 1, 2, 3, 4, with a second sequence 4, 6, 9, 12 that grows in a consistent, easy-to-use way for bigger servings. This kind of relationship reflects how you keep the core ratios steady while expanding the total amount you’re making, which is exactly what you want when prepping drinks quickly and accurately.

The base amounts are straightforward and memorable, and the corresponding larger amounts are derived in a way that’s practical for real-world prep—roughly threefold for most items after the first, making it easy to scale up without constantly recalculating. The other options show relationships that jump around or don’t scale in a reliable, predictable manner, which would be cumbersome when you're trying to adjust recipes on the fly.
