Answer & Explanation

Correct answer

1: Junior · 2: Cloud

The two blanks read the chart along different directions, so neither gives away the other. For the first blank you sum each bar from bottom to top: Junior = 60 + 35 + 45 = 140, Mid-level = 40 + 30 + 25 = 95, Senior = 18 + 12 + 20 = 50, Executive = 4 + 6 + 2 = 12. Junior is the tallest stack at 140, so it is correct; Mid-level at 95 is the runner-up, and Executive is the shortest.

For the second blank you instead add one color of segment across all four bars: Cloud = 60 + 40 + 18 + 4 = 122, Hardware = 35 + 30 + 12 + 6 = 83, Services = 45 + 25 + 20 + 2 = 92. Cloud is the largest at 122, so it is correct. Services is a trap because it has the single tallest Senior segment, but summed across all levels it trails Cloud; Hardware is the smallest unit overall.
