In a "choose one from a list" part with selection type set to "drop down list", the list has an empty option at the top of the list, so that the student is forced to make a choice.
In some cases, it's OK to have a default option selected, which could be arranged to be the first option in the list.
An example from Will Haynes is when you're asked to enter an angle either clockwise or counter-clockwise, with separate inputs for the amount and the direction. Having the clockwise direction selected by default would be convenient.
There should be a "begin blank" option, which when turned off would remove the empty option, so the first option is selected by default.
