Answer to Question 1

ANS: C

Answer to Question 2

ANS: B
Diets that contain a wide variety of foods are more likely to include complementary protein sources that would contribute to a higher overall dietary protein quality. A high protein intake does not necessarily ensure that the protein is high-quality protein. Amino acid supplements could result in an unbalanced intake of amino acids and actually reduce overall protein quality of the diet. The quality of specific types or cuts of meat does not affect the quality of the protein.
