18. A scatter plot of number of teachers and number of people with commerce degrees for cities in India reveals a positive association. The most likely explanation for this positive association is:

(a)

Teachers encourage people to get college degrees, so an increase in the number of teachers is causing an increase in the number of people with college degrees.

(b)

Larger cities tend to have both more teachers and more people with college degrees, so the association is explained by a third variable, the size of the city
