Revision material from the imported DVSA bank includes source-checked Lanekind learning corrections. These corrections are not newly issued official examination questions, and practice does not reproduce a live test paper.
A roof rack increases your car's wind resistance. This will cause an increase in fuel consumption, so you should remove it when it isn't being used. An aerodynamically designed roof rack or box will help reduce wind resistance to a minimum, but the rack or box should still be removed when it isn't in use.
