Figure 1
The horizontal axis ranges from 2021 to 2025 in increments of 1 year. The vertical axis ranges from 2.0 to 4.0 in increments of 0.4 units. The graph displays three lines, and is identified in a legend at the bottom. The first line labeled “Mean S C” begins near (2021, 2.35), increases to around (2022, 2.9), rises sharply to (2023, 3.95), and then remains nearly flat, ending close to (2025, 3.95). The second line labeled “Mean S T” starts near (2021, 2.3), increases more rapidly to about (2022, 3.3), continues rising gradually through (2023, 3.6) and (2024, 3.8), and ends just below 4.0 at (2025, 3.95). The third line labeled “Mean T E” begins near (2021, 2.4), increases steadily but more gradually to about (2022, 2.9), continues rising through (2023, 3.2) and (2024, 3.4), and ends near (2025, 3.9).
