Which details from the historical fiction piece "Marie Curie and the Discovery of Radioactivity" supports Marie's factual statement?

During a particularly rigorous winter, it was not unusual for the water to freeze in the basin in the night; to be able to sleep I was obliged to pile all my clothes on the bed covers. In the same room I prepared my meals with the aid of an alcohol lamp and a few kitchen utensils. These meals were often reduced to bread with a cup of chocolate, eggs or fruit.

A No one, the Curies included, had ever seen this element. Still, the husband-and-wife team had given it a name: radium.

B She also met the man who soon became her husband—Pierre Curie, a brilliant young physicist as promising (and poor) as Marie.

C In the winter, it was so cold that she emptied her closet, piling the clothes on the bed so she'd be warm enough to sleep.
