Hello, happy new year. pls help me.

Could you please tell me the words and phrases that apply to (1) to (6)? (In the case of a numerical value, it is 3 significant digits.)
The figure shows an inverting amplifier circuit using an operational amplifier. The gain of this circuit is (1)___ times. The potential at point a in the figure with respect to ground always has the property of being almost (2)___ volts regardless of the input, and this property is called (3)___

For this reason, current flows through the input circuit, and the magnitude of the input impedance is about (4)___ ohms, which is not large at all, so care must be taken. If terminal A is grounded and terminal B is used as the input terminal, this circuit will be a non-inverting amplifier and its gain should be (5)___ times. The input impedance in that case is considered to be almost (6)___ times.
