HW-04, Ex. 2, Option 1 Semantics Question

[kgwkyle]

Hi,

The option begins with stating, Make a tibble with one row per year, and columns for life expectancy and GDP per capita (or two other numeric variables) for two or more countries; is this referring to creating a total of two columns with each column being one country with values of both life expectancy and GDP per capita listed within each cell, or is it referring to creating a total of four columns, two for each country with each cell containing only one value (ie either life expectancy or GDP per capita, depending on the column)?

Thank you!
