Read the passage and choose the correct answers:
Marie Curie was born in Warsaw on November 7, 1867. She received a general education in local schools and some scientific training from her father. As a brilliant student, she harboured the dream of a scientific career, which was impossible for a woman at that time. To save money for a study tour abroad, she had to work as a private tutor. Finally, in 1891, Marie, with very little money to live on, came to Paris to realize her dream at the Sorbonne. Despite her difficult living conditions, she worked extremely hard. She earned a physics degree with flying colors, and went on to take another degree in mathematics. She met Pierre Curie in the School of Physics in 1894 and in the following year they got married. From then on, they worked together on their research. In 1903, Marie became the first woman to receive a PhD from the Sorbonne. She was the first woman in France to be a university professor. Soon after, she was awarded a Nobel Prize in Chemistry for determining the atomic weight of radium.
