Explanation:

William Ramsay focused mostly on the authors Luke and Paul. First, he paid attention to Luke. He studied both the Gospel of Luke and the Book of Acts, which are considered to have been written by the same author. Skeptical about their accuracy, Ramsay travelled to Asia Minor and tried to find more information about the places, characters and events that are mentioned in the gospels. After a lifetime of study, he concluded that the books were in fact historically accurate. Afterwards, he turned to Paul's letters, and also concluded that these were authentic.
