Never use why. How impresses science teachers more. Anyway, one question could be "How does the stomach resist the Hydrochloric acid present in itself?"
PS: The teachers like how because why is suposed to only deal with philisophical questions.

Mucus along with hydrochloric acid and digestive enzymes (such as pepsinogen) are secreted. Before pepsinogen is activated by hydrochloric acid, mucus lines the stomach (because the stomach is made of protein) to protect it from being digested by the activated digestive enzyme pepsin (which digests protein)
