DISCUSSION: The main idea is that Marie Curie was a pioneering researcher. She is not to blame for not figuring out the mechanism of radiation.
- Who knows? We’re not told who discovered quantum mechanics, or why. All we know is that quantum mechanics explained radiation. But radiation might not have been necessary for quantum mechanics.
- CORRECT. Marie Curie took us forward, even if she made some mistakes. Paragraphs 2-4 are devoted to rationalizing Curie’s failure to correctly explain radiation.
- Lines 56-60 contradict this. We should forgive Marie Curie’s failure to identify the real cause of radiation.
- Not so. Marie Curie couldn’t explain radiation, but she made other important discoveries, such as radium and polonium (lines 9-10).
- We’re not told whether Curie had any influence on chemists. And this is way off base: the passage was about Curie, the chemists were only mentioned in passing.
