While researching a topic, a student has taken the following notes:
  • In 1965, Yale University historians claimed that a world map called the Vinland Map was drawn in the fifteenth century.
  • Since that time, the map's age has been the subject of debate.
  • In 2021, researchers conducted a study to analyze the elemental composition of the map's ink.
  • Their analysis revealed that the ink contains a titanium compound not used in inks until the 1920s.
  • The researchers concluded that the map was drawn in the twentieth century.
The student wants to present the study and its findings. Which choice most effectively uses relevant information from the notes to accomplish this goal?

B
The Vinland Map, believed by some to have been drawn in the fifteenth century, was the focus of a 2021 study.
C
