Hi Angela,
I have found the kwiz question -
so 'va' is correct because as Maarten correctly states, the word 'héros' has an -s in the singular form.
So the important word was 'le' and not 'les' in this particular case.
But good question!
Angela,
I can’t see the example you are referencing but the correct expressions would be either ‘ le héros va … ‘ or ‘ les héros vont .. ‘.
The masculine noun ‘ héros ‘ has an ‘h aspiré’, and ends in terminal ‘ s ‘ in singular and plural form.
The feminine forms are ‘ l’héroïne va… ‘ or ‘ les héroïnes vont ..‘, as ‘ héroïne ‘ starts with an h muët, and does not have a terminal ‘ s ‘ in singular form.
If you think there is a mistake somewhere, best to report directly from the test, or separately to support.
