the smallest source of funds for school programs in 2012 is select.

Explanation:

Part (a)

To determine which sources increased or decreased, we analyze the bar heights for 1940 (blue) and 2012 (white):

• Parent - Teacher Associations: The blue bar (1940) is taller than the white bar (2012), so this source decreased.
• Private Donations: The white bar (2012) is slightly taller than the blue bar (1940), but the change is small. However, comparing with others:
• School District Funding: The white bar (2012) is taller than the blue bar (1940), so this source increased.
• Fundraising Events: The white bar (2012) is taller than the blue bar (1940), so this source increased.

So, for "Increased": School District Funding, Fundraising Events; for "Decreased": Parent - Teacher Associations.

Part (b)

No, the question says "In 1940, the smallest source of funds for school programs was School District Funding. Is this the smallest source of funds in 2012? The smallest source of funds for school programs in 2012 is Private Donations (comparing the heights: Private Donations bar is the shortest among the four in 2012).
