Is it difficult to predict the amount of lift that a wing geometry will generate?

(a) False

(b) True

I had been asked this question in an online quiz.

My question is from Prandtl’s Classical Lifting-Line Theory topic in portion Flow over Airfoils over Finite Wing of Aerodynamics

Correct answer is (b) True

Explanation: It is difficult to predict analytically the overall amount of lift that a wing of given geometry will generate. The lifting line theory yields the lift distribution along the span-wise direction, based only on the wing geometry and flow conditions.
