📜 Poem about Sektoren

Ob Wirtschaft, Kreis, ob Festplatten-Spur,
Der Sektor zeigt stets klare Kontur.
Ein Teil vom Ganzen, abgegrenzt und rein,
So muss ein wohlgeordneter Sektor sein.
Von Dienstleistung bis hin zur Industrie,
Die Sektoren prägen die Ökonomie.

(Whether economy, circle, or hard drive track,
The sector always shows a clear outline's knack.
A part of the whole, distinct and pure,
A well-ordered sector must be, for sure.
From services to industry's might,
Sectors shape the economy's light.)

🧩 Little Riddle

Ich bin ein Teil, doch nie allein,
kann Wirtschaft, Mathe oder Technik sein.
Auf Kreisen bin ich ein Tortenstück,
auf Festplatten bring' ich Daten zurück.
Mit 'der' steh' ich meistens da.

Wer bin ich denn? Na klar:

(I am a part, but never alone,
Can be economy, math, or technology's zone.
On circles, I'm a piece of pie,
On hard drives, I make data fly.
With 'der' I usually stand tall.

Who am I? You know it all:)
