Question

Which of the following choices is the closest in size to one serving of meat?

A. a coffee mug
B. an open palm
C. a baseball
D. a deck of cards

Answer 1

B. an open palm is correct, I think

Answer 2

I would have to say B. open palm of your hand

Only because it's portions for different size people.

A child portion would be different from an adult portion, and the palm is the only thing that measures by the size of the person.

Hope this helps. :)
