Question 1 of 3 free Medium

According to the US government's Centers for Disease Control and Prevention (CDC), 24 outbreaks of foodborne disease occurred across more than one US state in 2005 and 2006. Year and month of the outbreak are indicated. The etiology (the pathogenic organism, toxin, or chemical that caused the outbreak) is listed under Genus & Species, since most of the causes are bacteria or viruses. Illnesses, hospitalizations, and deaths caused by the outbreak are counted, if known. The entry "n/a" means "not available." For each of the following statements, select Yes if the statement can be shown to be true using the information provided. Otherwise, select No.

Correct answer: B

No. The only trick to this question is to recognize that it’s asking about outbreaks, not individual illnesses. That means we can find the answer without looking beyond the first column. There were 5 outbreaks in the first half of 2005 (any month between January and June would count as the first half of the year) and 8 outbreaks in the second half. There were only 3 outbreaks in the first half of 2006, and and 8 outbreaks in the second half. That makes for 8 outbreaks in the first half of both years (5 + 3 = 8) and 16 outbreaks in the second half of both years. This is exactly twice as many.

The table shows US energy production, in quadrillion BTUs, broken down by sources. "Nat. gas" refers to natural gas, which comes either as liquids or in dry form.

View explanation

Correct answer: B

Statement 1 is No. In 2001, Other energy production was 5.32 out of total production of 71.89, which is about 7.4%, less than 8%. So it is not true that Other sources never accounted for less than 8%.

Statement 2 is No. Nuclear electric production does not show a negative relationship with year over the period shown; it rises from 6.48 in 1992 to 8.46 in 2007, with several increases over time.

Statement 3 is No. Nuclear electric production rose from 7.86 in 2000 to 8.46 in 2007. The increase is 0.60, and 0.60 / 7.86 is about 7.6%, which is not more than 10%.
Question 3 of 3 free Medium

The table includes various data about libraries in the Netherlands during the period between 2001 and 2005, inclusive. Volumes include books, audiovisual (AV) materials, and other materials. "In collection" numbers are averages (arithmetic means) for the year, whereas "Lent out to public" numbers are totals for the year. All numbers except for the number of libraries are in thousands.

View explanation

Correct answer: B

Statement 1 is No. AV turns equal AV materials lent out divided by AV materials in collection. The values decline from about 2.97 in 2001 to about 2.54 in 2005, so the fewest turns were in 2005, not 2004.

Statement 2 is No. From 2001 to 2005, the number of libraries fell from 508 to 351, a decline of about 30.9%. Volumes in collection fell from 42,760 to 37,464, only about 12.4%, so volumes in collection did not have the greatest percent decline.

Statement 3 is No. Books in collection per registered user fell from about 8.55 in 2002 to about 8.41 in 2003, so it did not rise.

The table shows the arithmetic mean Systolic Blood Pressure (SBP) of the male population of selected countries, measured in mmHg. The means are age-adjusted, as if each country had the same age distribution as the world population.

Question 5 of 5 preview Medium

According to the United States Geological Survey, the 12 countries listed have substantial zinc-lead deposits. The category total deposits refers to the number of distinct locations where deposits can be found. The average age of the deposits is given in millions of years (MY). The total ore tonnage of deposits in each country is given in millions of metric tons (mm). Finally, the zinc grade and lead grade figures represent the percentage of the total ore tonnage that is made up of the metal in question (zinc or lead).
