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

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

A moment later, people passing by the School of Physics and Chemistry were treated to a sight not often seen on the fashionable streets of Paris in the early 1900s: a bareheaded young woman in a laboratory smock, ripping eagerly into the pile of heavy sacks and burying her hands in . . . dirt?

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.

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