Final answer:
All the options given, including 1 medium apple, 1 slice of bread, 1 cup cooked pasta, and 1 small baked potato, represent a portion of a carbohydrate-containing food. Apples contain simple carbohydrates while bread, pasta, and potatoes are sources of complex carbohydrates. Thus, there's no incorrect option based on the provided context.
Step-by-step explanation:
The question identifies different food items and asks which one does not represent a portion of a carbohydrate-containing food. To understand which of these options does not fit, we need to know that carbohydrates can be simple or complex. Complex carbohydrates are found in foods such as grains, vegetables, and potatoes while simple carbohydrates are found in fruits and sugary sweets.
Options a (1 medium apple), b (1 slice of bread), and d (1 small baked potato) are clear sources of carbohydrates. An apple is a source of simple carbohydrates, specifically fructose, while bread and potatoes contain complex carbohydrates, such as starch. Option c (1 cup cooked pasta) also contains carbohydrates; however, typically, pasta is not consumed in a 'medium,' 'slice,' or 'small' serving size relevant to the others listed. Depending on the type of pasta, it could vary in carbohydrate content due to different ingredients or processing methods. Therefore, all of the examples provided do represent a portion of a carbohydrate-containing food, assuming that we equate 'portion' to mean 'a serving size that contains carbohydrates'.
