assertion higher the range of an ammeter, smaller is its resistance.
reason to increased the range of the ammeter additional shunt needs to be connected across it.

Since shunt and galvanometer resistors are in parallel then ammeter resistance also will decrease. So higher the range less the resistance of the ammeter. To increase the range of ammeters we are adding additional shunt resistance.
The lower the resistance of an ammeter gives the higher range. The additional shunt is used to increase the range of an ammeter.
So, statement 1 is false and statement 2 is true.
