Question

1 review the skill
visuals allow authors to highlight important information and present data in different ways. for example, a graph can show how something changes over time. a chart can show comparisons among groups. photographs and pictures can appeal to readers emotions and help readers understand what a particular situation was or is like. authors use data to inform readers and support logical arguments.
2 refine the skill
by refining the skill of analyzing visuals and data, you will improve your study and test - taking abilities, especially as they relate to the ged® reasoning through language arts test. read the passage, and study the graph below. then answer the questions that follow.
the importance of vaccination
the centers for disease control and prevention has found that groups opposed to vaccination may claim that some diseases began to disappear before vaccines were introduced. better nutrition and cleanliness have certainly reduced disease. but vaccination remains an important part of keeping populations healthy.
the graph below shows that a dramatic decrease in incidence of measles began when the measles vaccine became widespread.
measles: united states, 1950 - 2001
this graph shows the numbers of cases on the vertical y - axis and years on the horizontal x - axis.

1. how does the graph help the author respond to anti - vaccination viewpoints? the graph shows that

a. vaccinations were more effective than cleanliness and nutrition.
b. vaccines have been effective in eliminating many diseases.
c. measles cases declined steeply after the vaccine was licensed.
d. measles cases rose and fell consistently before the vaccine was introduced.

1. why is the year the vaccine was licensed indicated on the graph?

a. to confirm how quickly cases declined
b. to indicate when the decline in cases began
c. to prove that cleanliness is unimportant
d. to explain why cases of measles declined
test - taking tips
review visuals carefully. it is important to notice, for example, that the numbers on this graphs y - axis represent hundreds of thousands of cases. these numbers show how important the vaccine is.

Explanation:

1. The graph shows a steep decline in measles cases after the vaccine was licensed, which directly counters anti - vaccination viewpoints. Options A and B generalize beyond what the graph shows. Option D is not what the graph emphasizes.
2. Indicating the year of vaccine licensing on the graph shows when the decline in measles cases began, correlating the introduction of the vaccine with the decrease in cases. Option A is not the main reason. Option C is not supported by the graph. Option D is too broad; the graph just shows the start of the decline.

Answer:

1. C. measles cases declined steeply after the vaccine was licensed.
2. B. to indicate when the decline in cases began
