2)1800s
3)1900s
4)still popular

Answer 1

Phrenology was most popular in the 1800s. It emerged in the early part of the century, particularly during the 1820s and 1830s, and continued to be influential into the later part of the century. By the early 1900s, however, it had largely fallen out of favor as a scientific theory. So the correct answer is: **2) 1800s**.
