Como probablemente sabréis, el GMAT sufrirá un cambio en junio de 2012: una de las dos secciones escritas del examen (AWA) será sustituida por una nueva sección que requerirá a los examinados interpretación de tablas, gráficos, tablas de datos, etc (más información en El nuevo GMAT ). La pregunta que muchos os haréis es si es conveniente hacer el examen ahora o esperar a que el cambio esté implantado. Pues bien, aquí tenemos un test ejemplo de cómo será esta nueva sección llamada Integrated Reasoning. (Las soluciones a este minitest se encuentran al final del artículo).

MULTI-SOURCE REASONING

Can you assimilate information from different sources?

Exports to China

In 2009, China was the biggest export market for several countries on many continents. Among these countries, Australia sent 21.8 percent, Brazil sent 12.5 percent, Japan sent 18.9 percent and South Africa sent 10.3 percent of its exports to China. Tables 1 and 2 provide another, perhaps more revealing measure of the impact of economic exports to China: the value of exports relative to the Gross Domestic Product (G.D.P.) for many of China’s major trading partners, including the European Union (E.U.), in 2009.

1. Based on the information provided, which one of the following quantities is closest to the total value, in 2009 U.S. dollars, of Australia’s and Brazil’s 2009 exports to China?

a. $19 billion
b. $31 billion
c. $34 billion
d. $53 billion
e. $64 billion

2. Based on the information provided, which one of the following quantities is closest to the total value, in 2009 U.S. dollars, of Japan’s 2009 exports to all countries?

a. $215 billion
b. $320 billion
c. $450 billion
d. $590 billion
e. $640 billion

3. For each of the following countries or regions, determine whether its 2009 exports to China can be shown, based on the given information, to have exceeded $100 billion in 2009 U.S. dollars. Indicate Yes if the exports can be shown to exceed that value. Otherwise indicate No.

____ European Union
____ Japan
____ Nigeria
____ Taiwan

4. Examine each of the following statements and indicate Yes if the statement can be inferred from the information provided. Otherwise indicate No. All amounts are measured in 2009 U.S. dollars.

____ India’s exports to China exceeded Russia’s exports to China.
____ The amount of exports to China from all the countries of South America combined exceeded $10 billion.
____ Australia’s exports to China accounted for more than one-fifth of Australia’s total exports.
____ South Korea’s exports to China exceeded Malaysia’s exports to China.

1. To the nearest 10th of a percent, ___ percent of businesses in the graph had positive growth in both years.

TWO-PART ANALYSIS

Can you solve two-part problems?

Workers in an office are placed into three groups, each containing 20 workers. All workers are in at least one group. Any two groups have exactly 10 members in common.

In the table below, identify two numbers from the list of possible answers that are jointly consistent with the given information: in the first column, mark the row that indicates the total number of workers in the office; in the second column, mark the row that indicates the number of workers who are members of all three groups. Make only two selections, one in each column.

Total Workers | Workers in All Three | Possible Answers

___________|___________________|________4

__________|_________________ |________8

__________|_________________ |________10

__________|_________________ |________18

__________|_________________ |________34

__________|_________________
