A newspaper article quotes a study: 'Researchers found that city dwellers are 20% more likely to develop anxiety disorders.' Without additional context, a cautious reader would first ask:
Answer: 20% more likely than whom, and how was the comparison group defined
Relative risk statements (X% more likely) are only meaningful when the baseline comparison group is clearly identified.
A passage contains this transition: 'Conversely, rural hospitals reported the opposite trend.' The word 'conversely' signals:
Answer: A contradictory or contrasting relationship to the preceding idea
Conversely introduces information that stands in contrast to what was just stated.
An informational text includes a sidebar titled 'Key Terms.' The primary function of such a sidebar is to:
Answer: Define specialized vocabulary to support reader comprehension
Key Terms sidebars exist to give readers quick access to definitions of technical or unfamiliar words used in the text.
A climate report states: 'Model projections suggest temperatures could rise between 1.5°C and 4°C by 2100.' The range given (1.5°C to 4°C) reflects:
Answer: Uncertainty arising from different assumptions and scenarios in the models
Climate model ranges represent scenario uncertainty—different emissions pathways and model parameters produce a spread of possible outcomes.
A text states: 'Per capita income in Region X is $45,000.' A student is comparing this to Region Y's total income of $9 billion. To make a valid comparison of individual wealth, the student should:
Answer: Find Region Y's per capita income by dividing by its population
Per capita income (per person) must be compared to another per capita figure; dividing Region Y's total income by its population makes the figures comparable.
An author describes a study as 'double-blind.' In an informational context, this term most accurately means:
Answer: Neither the researchers nor the participants knew who received the treatment
Double-blind means both participants and researchers administering the study are unaware of group assignments, reducing bias.
A passage ends with: 'Future research is needed to determine whether these findings hold across different demographic groups.' This concluding sentence primarily serves to:
Answer: Acknowledge a limitation and identify a direction for further study
Acknowledging the boundaries of current findings and pointing to future research is a standard way authors signal honest limitations.
