Question

study the bar graph (and the question about measles cases reported in the united states) to answer which statement about the year is correct? (graph: us measles cases by year) options: a. other diseases became more common than measles in the united states after the year 2001. b. people have learned proper hygiene techniques to prevent the spread of measles. c. the number of measles cases suddenly increased in the year 2014. d. vaccination programs have never reduced the number of measles cases since the year 2014.

Explanation:

To solve this, we analyze each option against the bar graph "US Measles Cases by Year":

• Option A: The graph shows measles cases, not other diseases, so we can't conclude about other diseases. Eliminate A.
• Option B: The graph doesn't provide info on hygiene techniques. Eliminate B.
• Option C: By visually inspecting the bar heights, the bar for 2014 is the tallest, so the number of measles cases increased notably in 2014. This matches.
• Option D: The graph doesn't show vaccination programs' impact post - 2014 (no data after 2014 shown to confirm a decrease). Eliminate D.

Answer:

C. The number of measles cases increased notably in the year 2014.
