Question

how would you use your hands to determine 1 tablespoon of margarine?
use the tip of your thumb.
use one cupped hand.
use two cupped hands.
use a palm.

Explanation:

In cooking and nutrition contexts, the tip of the thumb is a common visual and tactile reference for approximating 1 tablespoon. One cupped hand is typically more for larger volumes like a cup, two cupped hands would be even larger, and a palm is not a standard reference for 1 - tablespoon measurement.

Answer:

Use the tip of your thumb.
