Read the first 7 Interpreting Informative Texts flashcards as text

  1. A public health report states: 'Among adults aged 18–44, vaccination rates rose from 34% to 61% over three years.' What is the percentage point increase?

    Answer: 27 percentage points

    61% − 34% = 27 percentage points, which is the absolute difference in the two rates.

  2. A technical document contains the phrase 'as previously defined.' A reader encountering this phrase should:

    Answer: Refer back to the earlier definition given in the text

    The phrase signals that the author established a specific definition earlier that should be applied to the current usage.

  3. A bar chart shows four categories labeled A, B, C, and D. Category B's bar is twice the height of Category A's bar. This means:

    Answer: The value represented by Category B is twice that of Category A

    In a standard bar chart, bar height directly represents the measured value, so B's value is double A's value.

  4. An author writes: 'Data were collected from a convenience sample of university students.' A limitation the reader should acknowledge is:

    Answer: The findings may not generalize to all adults

    Convenience samples are not randomly selected, so results from one narrow group may not represent broader populations.

  5. A passage uses italics for the phrase terra nullius and then immediately provides its meaning. This formatting choice most likely indicates:

    Answer: The term is a foreign or technical expression being introduced to the reader

    Italics conventionally signal foreign words or newly introduced technical terms, especially when a definition follows.

  6. A policy brief concludes: 'Based on the evidence above, the committee recommends expanding the program.' The word 'recommends' signals that the statement is:

    Answer: A prescriptive judgment based on the preceding evidence

    Recommendations are value-laden conclusions that go beyond description, suggesting a course of action supported by evidence.

  7. A text includes a table with a footnote marked by an asterisk (*) reading: 'Data unavailable for 2018.' How should a reader interpret figures in the 2018 column?

    Answer: The 2018 column contains no valid data and should not be used for comparison

    The footnote explicitly states that 2018 data are unavailable, making any values in that column unreliable for analysis.
