Correct answer: A

Rationale: The correct answer is 'Beans.' Beans are a rich source of plant-based protein, making them the best option among the listed foods for protein content. Red peppers, asparagus, and celery are not significant sources of protein compared to beans, hence they are incorrect choices for this question.

4. An imbalance of which nutrient may elicit delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter?

A. Zinc
B. Iron
C. Sodium
D. Potassium

Correct answer: B

Rationale: The correct answer is B: Iron. The provided extract mentions that iodine deficiency can cause delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter. Zinc, Sodium, and Potassium are not associated with these specific symptoms. Zinc deficiency can lead to other health issues but not the ones mentioned. Sodium and Potassium imbalances do not typically result in the symptoms described in the question.
