It is asking, how much did the chirps increase between these temperatures. From 40-50 it increased 40 from 50-60 it increased another 40 etc. This does create a line.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
