Spurred by the discovery that a substance containing uranium emitted radiation, Marie Curie began studying radioactivity in 1897. ███ █████ ██████ ████ ███ ██████ ███ █████████ ███ █████ █████ ███ ████ ██████ ████████████ █ ███████ ████ ███ █████ ██ ███████ ████████ ███ ██████████ ████ ██ ███ ████ ███████████ ████ ████████ ██████ ██ ███ ██████████ ████ ███████████ ████ ███████ ██ █████ ███ █████ ███████████ ████████ █████ ███ ████ ██ ███████ █ ████ ██ ██████████ ███████ █████████ ████████ ███ ███████ ███████ ███ █████████ ██ ███ ████ ██ ███████████ █████████ ███ ██████████ ████ ███████ ███████ █████████ ██ █ ██████████ █████ ████ ██ ██████ ██ ██████████ █████ ██ █████ ████████ █████ █████████ ████ ███ ████████ ████ ███ █ █████ ███████ ███ █████████ ████████████ ███████ █████████ ████████ ██ ██ ████████████ ████ ██ ███████████ ██████████ ███████ █████████ ███ ████████████ █████████ ███ ███ ██████ ██ █████████ █
Intro topic ·
Marie Curie's discoveries related to radiation
Discovered polonium and radium. Also disocvered that uranium emitted radiation at a constant rate. But, she couldn't explain what causes raidation.

Critics and response ·
Some fault Curie for not discovering cause of radiation and decreasing rate; author says it wasn't her fault
Curie didn't have the evidence that we have today.
Support for author's response ·
Various radioactive isotopes weren't available to Curie or decayed to slowly to learn anything about rate

Additional support ·
Nature of atom was being debated during Curie's time
Physicists (like Curie) believed that matter couldn't be divided indefinitely. In other words, there's nothing smalling than the atom.

Which one of the following ████ ██████████ ██████ ███ ███████ ████ ██ ███ ████████

It is unlikely ████ ███████ █████████ █████ ████ ████ █████████ ███████ ███ ███████████ █████████████ ██ █████ █████ ██████ ██ █████████████ ██ ███ ██████ ██ ██████████████
Not supported, because we’re never told that Curie’s work helped the development quantum mechanics. Quantum mechanics is

Although later shown ██ ██ ██████████ ███ █████████ ███████████ █████ ███████ ██████████████ ████████ █ ███████████ ████ ███████ ██ ███ ████ ██ ███ ████████ ███████████ ██ ██████████████
This best captures the main point, which is that Curie

Though the scientific ████████████ ██ █████ █████ ████ ██████████ ██ ██████ ███ ██████ ██ █████████ ██ ███ ███████ ██ █████████ ███ █████████ ██ ██████████████
The author defends Curie from criticism about her research into radiation. We have no reason to think the author considers her career blemished. In any case, even if you think there’s support for the claim that her career is blemished, the focus of the passage is on her contributions and impact, not on her allegedly diminished career.
d
The commitment of █████ █████ ███ █████ ██████████ ██ ███ ████ ██ ███ ███████████ █████ ██ ███ ████ █████████ ████ ████ ██████████ ████████ ██████████████ ████ ██████████████
Not supported, because Curie was able to conduct useful investigations into radioactivity. She may not have been able to come to a true understanding of the mechanism underlying radioactivity, but she still conducted experiments that helped pave the way for later breakthroughs.

Although today's theories ████ █████ ██ ██ ██ █████████████ █████ ███████ ████████ ████ ███ ███████ ███ ██████ ██ █████████████ ██████ ██████ ███ █████████ █████ ██ ███ █████
Not supported, because Curie’s research didn’t prove the chemists wrong concerning the model of the atom.
