There are two cities in Guyana Georgetown and Berbice. In Suriname the three largest cities are Paramaribo, Lelydorp, and Nieuw Nickerie. So, Suriname has enough cities to qualify, but sadly Guyana does not.
I'm sorry it's my first quiz I completely forgot Uruguay, I'm gonna change it now. But I won't include Guyana or Suriname because I don't think anybody knows 2 cities apart from Georgetown and Paramaribo.
I recommend using Format as "Groups of Things". Your quiz will look nicer and more organised. This option can be found in Step 3. Click the box which says Advanced and select the bottom option. This option will consider stuffs in your first column as category names and group them accordingly. Very useful!
