Take the following as truth: Map 33 shows the distribution of child (most of southern England) and of bairn (north of a slightly wavy line between Boston, on the Wash to the east, and Lancaster, on the west coast).
Then the following statement: "Map 33 shows us that the word child was used universally across England while bairn only came into use in Scotland." is true, false, or inconclusive?
Answer: False
