Rationale: Functional foods are specifically designed to promote health benefits beyond basic nutrition. Fortified foods (choice
A) are those with added nutrients that are not originally present, enriched foods (choice
B) have nutrients added back that were lost during processing, and health-enhancing foods (choice

Correct Answer: B

Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases).
Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables.
Choice C is incorrect as it describes a negative correlation where variables move in opposite directions.
Choice D is incorrect as a positive correlation implies a relationship between the variables.

Correct Answer: B

Rationale:
Choice B is the correct answer. A poor diet can increase the risk of developing chronic diseases due to the lack of essential nutrients or the presence of harmful components like excessive sugar, salt, or saturated fats. While diet plays a significant role in the development of chronic diseases, it is not the sole cause (choice
C).
Choice A is incorrect because diet does indeed have a significant impact on chronic diseases.
Choice D is not the best answer as it does not acknowledge the negative impact of a poor diet on chronic diseases.

Correct Answer: A

Rationale: When a child is suspected to have a fracture, it is essential to immobilize the affected limb to prevent further injury. Seeking immediate medical evaluation is crucial for an accurate diagnosis and appropriate treatment. Applying heat to a suspected fracture can worsen the condition by increasing swelling and pain. Allowing the child to continue normal activity can lead to further damage. Administering only over-the-counter pain relief is insufficient and does not address the need for immobilization and professional evaluation.
