Final answer:
Unlike Whitney Houston's performance of 'The Star-Spangled Banner,' Namika's rendition of 'The Song of the Germans' includes the audience singing along, likely because it is a patriotic song that encourages audience participation.
Step-by-step explanation:
In this case, the difference between Whitney Houston's performance of 'The Star-Spangled Banner' and Namika's rendition of 'The Song of the Germans' is that the audience sings along in Namika's performance. This is likely because 'The Song of the Germans' is a patriotic song that encourages audience participation.
Many national anthems, like 'The Star-Spangled Banner,' are traditionally performed by a solo singer or a choir. However, in certain instances, national anthems may have versions that involve audience participation. This can create a greater sense of unity and patriotism during performances. Namika's rendition of 'The Song of the Germans' is one such example, where the audience is encouraged to join in and sing along.
