Show answer and explanation

Correct answer: (D) P–5;Q–1;R–4;S–2

Explanation

The Empire State Building uses the shear-truss classification here; John Hancock expresses a braced/trussed tube; Taipei 101 uses outriggers; Sears/Willis Tower is the bundled-tube example. Thus 5, 1, 4, 2, D. The classification concerns lateral-load-resisting systems.
