Explanation:

Step1: Check Allied vs Central soldiers

Allied powers (blue bars: Russia, Great Britain, France, US, Italy, Other) have taller cumulative bars than Central powers (purple bars: Germany, Austria-Hungary, Ottoman, Other).

Step2: Check US soldier count

US bar is shorter than Russia, Great Britain, France; not the tallest.

Step3: Check US soldier number

US bar is above 2,000,000 (between 4-5 million), so not fewer than 2 million.

Step4: Calculate total soldiers

Sum approximate values: Russia (~12M), GB (~9M), France (~8M), US (~4.5M), Italy (~5.5M), Other Allied (~2.5M); Central: Germany (~11M), Austria-Hungary (~8M), Ottoman (~3M), Other Central (~1.5M). Total ≈ 12+9+8+4.5+5.5+2.5+11+8+3+1.5 = 65M >30M.

Answer:

The Allied powers had more soldiers than the Central powers., Over 30 million people fought in World War I.
