<h2>Answer: Marie Curie
</h2>
Marie Curie's notebooks, as well as all of her belongings, including her clothes, were contaminated with ionizing radiation. In fact, those of her husband also, because this couple of scientists discovered the radioactivity of several elements, helping the advance of science, but <u>did not know about the consequences of dealing with these materials without adequate protection.
</u>
It should be noted that Curie's notes are stored in the basements of the National Library of France, stored in thick lead boxes and those who wish to access these documents must follow the appropriate protocol to treat radioactive material, wear appropriate clothing and sign a responsibility  agreement before allowing them to review the documents.

Answer:
Explanation:
This refers to the story of aspiring sculptures, Giovanni de Nowheresville, and Mario de Wealthton. They had the same start at the same university, however, their lives afterward were very much different.
<u>Mario returned to his coast city which was rich because of the number of merchants</u>. The number of well-off people was large and they could afford to have art pieces in their home, therefore Mario was often hired to create sculptures. First, he made them by the order, and afterward, he would make the name for himself and he would make them as he wanted. 
<u>Giovanni, however, returned to his small town that was centered around farming.</u> He had to work at the farm to support himself, so he finished sculptures slowly. No one in his environment had money to spend on the art, so Giovanni couldn't earn off it and could never make it as famous artists.
 
<u>Therefore, we see that the key was the environment and the opportunity each of the artists had - Mario became successful because he lived in a rich environment that could support him, and he had the change to live off from art, while Giovanni had to farm for a living and his environment did not have money for the art pieces. </u>
