To determine why the side dish in the healthier lunch option costs much more compared to the current lunch option, let's analyze the factors provided:
1. Larger Portion: While larger portions can contribute to higher costs, the table doesn't provide information about portion sizes.
2. Substitute Item that is More Expensive: It is common for healthier options to use substitute ingredients that are more expensive. These substitutes may be organic, non-GMO, or contain higher nutritional value, which typically drives up the cost.
3. Taste Better: Taste is subjective and doesn't necessarily justify a higher cost. Quality or healthier ingredients could influence taste, but taste alone isn't a definitive reason for a higher price.
4. Reduces Childhood Obesity: This is a benefit rather than a cost factor. The effectiveness in reducing obesity doesn't directly justify the increased price.
Among the options given, the most plausible reason for the higher cost of the healthier side dish is:
It uses a substitute item that is more expensive.
This reasoning aligns with the cost analysis, as substituting less healthy ingredients with healthier ones usually raises the expense. Therefore, the side dish in the healthier lunch likely costs more due to the use of more expensive substitute items.
