Cognitive Effects of Premium Coffee Consumption

Very Hard Must Be True / Most Strongly Supported Inference Support

A new study investigates the long-term effects of premium coffee consumption on cognitive functions. Researchers tested two groups: one that regularly consumed premium coffee and another that abstained from caffeine entirely. After two years, they found that the coffee consumers showed a significant improvement in tasks requiring sustained attention, while the non-caffeine group exhibited a slight decline in similar tasks. Furthermore, participants in the coffee-drinking group also reported higher levels of alertness throughout the day.

Given this study, which of the following conclusions can be most strongly supported?

Premium coffee consumption is likely to improve cognitive functions related to sustained attention.

Abstaining from caffeine entirely will invariably lead to a decline in cognitive function.

The effects of premium coffee on cognitive functions are equivalent to other forms of caffeine.

High levels of alertness are exclusively due to the consumption of premium coffee.

Non-caffeine consumers are likely more prone to cognitive decline than habitual premium coffee users.
