In the first paragraph of the attached passage, which has been reproduced here, where should sentence [5] be placed in order to make it most logical?
[1]Practicing medicine is not a new concept. [2]People suffering from any number of diseases and ailments have been visiting physicians for centuries, even when a physician could do hardly more than sit at patients’ bedsides and monitor their vitals. [3]Trained physicians can now provide a higher level of care at state-of-the-art facilities with the assistance of experts such as nurses, radiologists, and other specialists. [4]Some, similarly, believe that the healthcare industry is not adapting quickly enough to one of the most important innovations of the 21st century. [5]Thankfully, healthcare has come a long way since then.
