Question

1. david garcia is serious about his glass blowing career. which text from the book shows this? \believe it or not, that cool glass was made in a super - hot furnace.\ \people have made glass like this for two thousand years.\ \i built the furnace. i built heating devices. i built the ovens.\ \some glass is made in factories, but the most beautiful glass is tooled by hand.\

Explanation:

The statement "I built the furnace. I built heating devices. I built the ovens." shows that David Garcia is actively involved in creating the necessary equipment for his glass - blowing career. This level of hands - on involvement in building the tools of his trade indicates a serious commitment to his career. The other statements are more about general facts about glass - making (e.g., where it's made, how long it's been made, factory vs. hand - made) rather than showing his personal serious effort in his career.

Answer:

"I built the furnace. I built heating devices. I built the ovens."
