English Sentence Correction QUESTION #4913
Question 1
A recent study of ancient clay deposits has provided new evidence _____ contributed to the extinction of the dinosaurs and many other creatures some 65 million years ago.
  • supporting the theory of global forest fires ignited by a meteorite impact that
  • supporting the theory that global forest fires ignited by a meteorite impact✔️
  • that supports the theory of global forest fires that were ignited by a meteorite impact and that
  • in support of the theory that global forest fires were ignited by a meteorite impact and that
Correct Answer Explanation
It clearly expresses the theory: global forest fires ignited by a meteorite impact contributed to the extinction. In option A, the pronoun 'that' ambiguously modifies either 'meteorite impact' or 'fires.' Options C and D add unnecessary 'and that,' creating grammatical awkwardness. Option E changes the meaning by implying the meteorite directly caused the extinction rather than the forest fires.
