b. describe a change over time in the pie charts.

Explanation:

Part A

Step1: Identify the 1968 pie chart

Look at the pie chart labeled 1968.

Step2: Find the mandatory spending segment

The legend shows mandatory spending is the white segment. In 1968's pie chart, the white segment is labeled 28%? Wait, no, wait. Wait, the 1968 pie chart: let's check the labels. Wait, the 1968 pie chart has three segments: the dark gray (net interest) is 6%, the light gray (discretionary) is 66%? Wait, no, maybe I misread. Wait, the legend: white is mandatory (automatic), dark gray is net interest, light gray is discretionary. So 1968: white (mandatory) is 28%? Wait, no, the 1968 pie chart: let's see the numbers. The 1968 pie chart: 6% (dark gray, net interest), 28% (white, mandatory), 66% (light gray, discretionary)? Wait, no, 6 + 28 + 66 = 100? 6+28=34, 34+66=100. Yes. Wait, but the question is part A: Identify the percentage of the budget that was mandatory spending in 1968. So from the 1968 pie chart, the white segment (mandatory) is 28%? Wait, no, wait the 1968 pie chart: the numbers are 6% (net interest, dark gray), 28% (mandatory, white), 66% (discretionary, light gray). So the mandatory spending in 1968 is 28%? Wait, no, maybe I got the legend wrong. Wait, the legend says: white is Mandatory Spending (Automatic), dark gray is Net Interest, light gray is Discretionary. So 1968: white (mandatory) is 28%? Wait, the 1968 pie chart: the white part is 28%, dark gray 6%, light gray 66%. So part A answer is 28%? Wait, no, wait the 1968 pie chart: let's check the numbers again. The first pie chart (1968) has three parts: 6% (dark gray), 28% (white), 66% (light gray). So mandatory spending (white) is 28%? Wait, maybe I made a mistake. Wait, the 1968 pie chart: the labels are 6% (net interest), 28% (mandatory), 66% (discretionary). So part A: the percentage of the budget that was mandatory spending in 1968 is 28%? Wait, no, wait the 1968 pie chart: the white segment is 28%? Let me confirm. The 1968 pie chart: 6% (net interest, dark gray), 28% (mandatory, white), 66% (discretionary, light gray). So 6 + 28 + 66 = 100. Yes. So part A answer is 28%? Wait, but maybe I misread. Wait, the 1968 pie chart: the white part is 28%? Let me check the other years. 1983: 14% (net interest, dark gray), 34% (mandatory, white), 48% (discretionary, light gray). 14+34+48=96? No, 14+34=48, 48+48=96? Wait, that can't be. Wait, maybe the 1983 pie chart: 14% (net interest), 34% (mandatory), 48% (discretionary). 14+34=48, 48+48=96? No, that's 96. That's a mistake. Wait, maybe the 1968 pie chart: 6% (net interest), 28% (mandatory), 66% (discretionary). 6+28=34, 34+66=100. Correct. 1983: 14% (net interest), 34% (mandatory), 48% (discretionary). 14+34=48, 48+48=96? No, that's 96. So maybe a typo, but the 1968 is 6+28+66=100. So part A: mandatory spending in 1968 is 28%? Wait, no, wait the 1968 pie chart: the white part is 28%? So part A answer is 28%?

Step1 (Part B): Analyze the change over time

Look at the pie charts for 1968, 1983, 2018, 2028*. Let's track each category:

• Mandatory Spending (white): 1968 (28%), 1983 (34%), 2018 (61%), 2028* (64%). So it's increasing over time.
• Net Interest (dark gray): 1968 (6%), 1983 (14%), 2018 (8%), 2028* (13%). Fluctuates but overall? 6→14→8→13.
• Discretionary (light gray): 1968 (66%), 1983 (48%), 2018 (31%), 2028* (23%). Decreasing over time.

So a change over time: Mandatory spending (automatic) has increased significantly from 1968 (28%) to 2028* (64%). For example, in 1968 it was 28%, in 1983 34%, 2018 61%, and projected to 64% in 2028, showing a steady increase. Alternatively, discretionary sp…

Answer:

(Part A):
