Answer
Lower. Reduced albumin will result in less osmotic pressure and a lower level of fluid in side A.
Work Step by Step
If the albumin concentration on side A was half of what it was in the original experiment, then the fluid on that side would reach a lower level than before at equilibrium. Because the concentration of water is greater on side B than side A, water will flow down the concentration gradient to side A (osmosis). Since we cut the albumin concentration on side A in half, the starting concentration of water is double on side A in this new experiment than in the original experiment. This reduces the "slope" of the concentration gradient and results in slower/less filtration (less osmotic pressure).
The more nonpermeating solute (albumin) there is in A, the greater the osmotic pressure and the higher the fluid level.
