Evaluating Dog and Cat Food Preferences

Hard Critical Reasoning Evaluating Data Arguments

A research team conducted a survey of 1,000 pet owners regarding their pets' dietary preferences. The survey revealed that 70% of dog owners and 50% of cat owners prefer premium pet food over regular brands. Based on these findings, the research team concluded that premium pet food is more popular overall among pet owners. However, they did not factor in the distribution of dog and cat owners within the surveyed population.

Which of the following, if true, would most seriously weaken the conclusion drawn by the research team?

The vast majority of the respondents were dog owners.

Many cat owners reported never buying premium food.

Sales data indicates that regular pet food outsells premium food.

The survey included a disproportionate number of households with multiple pets.
