Source: — Sentence Correction |

The theory propounded from the sentence is that global forest fires ignited by meteorite impact caused the extinction of dinosaurs and other species 65 million years ago.

Option A - Incorrect
This option is saying that global forest fires caused the extinction of dinosaurs and other species, not meteorite impact.

Option B - Correct
It supports the claim that meteorite impact ignited the global forest fires to cause extinction.

Option C - Incorrect
This answer is too wordy! It states that the evidence provided didn't cause extinction.

Option D - Incorrect
This answer choice doesn't fully justify the theory propounded that the past occurrence caused the extinction 65 million years ago.

Option E - Incorrect
This option is not clear enough as it doesn't state the facts. It only assumes that global forest fires ignited by the meteorite impact caused dinosaurs' extinction.
