Statement I : Al is more electro positive than Tl.Statement II : Al2O3 is more basic than Tl2O.

Electronegativity order : B > Tl > In > Ga > AlElectropositivity order : B < Tl < In < Ga < AlElectropositivity order  ∝ Metallic nature Al2O3 is amphoteric oxide.→ Tl+1 oxidation is more stable.Therefore Tl+1 compounds are more similar to that of  IA group compounds. IA group oxides and hydroxides are basic in nature and hence Tl(OH) and Tl2O are also basic in nature.Hence basic strength order : Tl2O > Al2O3
