In a 2017 study, Nitika Sharma and Rekha Dayal found that for consumers who value environmental conservation, their likelihood of purchasing a product increased when their perception of the product's effectiveness at addressing an environmental issue increased—in other words, the more environmentally friendly a product is perceived to be by a consumer, the more likely that consumer is to buy it. Subsequently, another research team conducted a study of various demographic groups in Chile, investigating participants' intention to purchase a new food product, and found that, on average, middle-aged adults gave the food product a higher environmental effectiveness rating than any other demographic group did. Assuming that the results of Sharma and Dayal's study are broadly applicable, this finding suggests that ______

there is not a meaningful difference in the average likelihood of purchasing environmentally friendly products among the demographic groups included in the study.

the new food product is less appealing to middle-aged adults than other similar products on the market are.

middle-aged adults might be more likely than participants in the other demographic groups to purchase the food product.

middle-aged adults likely prioritize other factors over a product's environmental sustainability when making purchasing decisions.
