Answer: A hard g makes a "guh" kind of sound. A soft g makes a sound like a j ("juh"). A soft g is followed by an "e", an "i", or a "y". Nougat has a hard g.
Explanation: The g in nougat makes a guh sound, not a juh sound, so it's a hard g. The g also doesn't have an "e", "i", or "y" right after it to make it soft.
