Query: Quotients, $\ell_\infty$ and abstract Ces\`aro spaces   Investigating some re-arrangement properties of the norm in the quotient
spaces $X/X_a$ we determine the properties of the spaces $X$ guaranteeing the
existence of a lattice isometric copy of $\ell_\infty$ in the abstract Ces\`aro
spaces $CX$.
