The NG section of the engine powers which device?

Explanation:
In a turboshaft engine, the gas generator speed (Ng) drives the core compressor network. The energy from the gas generator turbine is used to turn the high‑pressure compressor, which is the N2 section. So the NG section powers the N2 section. The N1 section is the low‑pressure spool and is not directly driven by Ng, and the piston section is not part of a turbine/shaft engine like this.
