share of world gdp by country (2011)
the single country with the worlds largest gdp is
the member countries of the european union have the same gdp as
together, these four countries and the european union have > half of the worlds total gdp.
us: 21%
european union: 25%
china: 11%
japan: 8%
india: 3%
all others: 32%

Explanation:

Step1: Analyze the pie chart

The pie chart shows the share of world GDP by country in 2011. The categories are US, European Union, China, Japan, India, and All others with their respective percentages: US (21%), European Union (25%), China (11%), Japan (8%), India (3%), and All others (32%).

Step2: Determine the single country with the largest GDP

We need to consider single countries (excluding the European Union which is a group of countries). Among US, China, Japan, India, the US has 21%, China has 11%, Japan has 8%, India has 3%. So the US has the largest share among single countries.

Step3: Find the GDP share of EU

The European Union's share is 25% (from the pie chart), and the US's share is 21%, so the member countries of the European Union have the same GDP share (25%) as? Wait, the question says "The member countries of the European Union have the same GDP as >" and "Together, these four countries (US, China, Japan, India) and the European Union > half of the world’s total GDP." Let's calculate the sum of US (21%), China (11%), Japan (8%), India (3%), and European Union (25%): 21 + 11 + 8 + 3 + 25 = 68%, which is more than 50% (half).

Step4: Fill in the blanks

1. The single country with the world's largest GDP is the US (21% is the largest among single countries).
2. The member countries of the European Union have the same GDP share (25%) as? Wait, maybe a typo, but from the chart, the European Union's share is 25%, and "All others" is 32%, no. Wait, the first blank: looking at the bar, the first bar is for the single country with largest GDP, which is US (21%? No, wait the pie chart: US is 21%, European Union 25%, All others 32%. Wait, maybe the first blank is "the US" (since US is a single country with 21%, and All others is a group, European Union is a group). Then the second blank: "the member countries of the European Union have the same GDP as >" maybe the bar for EU is 25%, and the US bar is 21%, no. Wait, maybe the first blank: the single country with largest GDP is the US (21% among single countries: US 21%, China 11%, Japan 8%, India 3%). Then the European Union's share is 25%, so the member countries of EU have the same GDP as... Wait, the third part: together these four countries (US, China, Japan, India) and EU: 21 + 11 + 8 + 3 + 25 = 68% > 50% (half).

Answer:

1. The single country with the world's largest GDP is the US.
2. The member countries of the European Union have the same GDP share (25%) (maybe compared to a group, but from the chart, EU is 25%).
3. Together, these four countries and the European Union have more than half of the world’s total GDP (68% > 50%).
