Suppose a structure and an array are created with the code
Structure Nation
Dim name As String
Dim continent As String
Dim population As Double 'in millions
Dim area As Double 'in square miles
End Structure
Dim nations(191) As Nation
in the Declarations section of the Code editor and the array is filled with data for the 192 member nations of the UN. What will be displayed in the list box when the following code is executed?
Dim query = From country In nations
Order By country.area Descending
Select country.name, country.population
lstBox.Items.Add(query.First.name)
lstBox.Items.Add(1000000 * query.First.population)
A) the name and population of the smallest country in the UN
B) the name and population of the largest country in the UN
C) the name and population of the least populous country in the UN
D) the name and population of the most populous country in the UN

The query sorts the nations by their area in descending order, meaning the largest nations will come first. The code then selects the name and population of the first (i.e. largest) country in the sorted list and adds them to the list box. Therefore, the code will display the name and population of the largest country in the UN.
