how should i end this paragraph?!?!?!?

Question

During the first stage of a fire, the source, usually a dry material, flammable gas or liquid is ignited. As the source oxidizes from the igniter, the small flame slowly grows, coincidently releasing toxic gases such as carbon dioxide and carbon monoxide (only after long periods of time) (Macmillan, Palgrave. "Fire” Wikipedia. 09 Nov 2006. 12 Nov 2006 ). Occasionally, very flammable sources skip this stage (or proceed from the first) and go straight to stage 2: free or open burning. This stage basically consists of the fire eating away at its surroundings, slowly, but steadily, using up the surrounding oxygen. As the oxygen depletes, a rapid explosion signals the beginning of stage 3: flashover. Because of the limited amount of oxygen (which normally would absorb the dedense smoke particles) the resulting smoke is a deep black with temperatures reaching at least 1000 Celsius! How should i wrap up this paragraph?

Answer 1

Once all the oxygen has been depleted the fire will burn itself out. Any fire must have oxygen to continue to burn. Different types of material burn at different temperatures and also determine the color of the smoke and the flame.

Answer 2

Oh, gawd..Restate your msp, or the "topic sentence" or your paragraph. R u plagerizing?

Answer 3

with All in all, what i learned is that
