Answer:
Nima and Natasha are absolutely correct.
Step-by-step explanation:
When connecting two resistors in series, their resistances add:

which means that whenever we add a resistance in series, their magnitudes will add, giving us a resistance that is greater than the original resistance, which will demand less current from the battery because of ohm's law:

So, the greater the resistance, the smaller the current.
When connecting two resistors in parallel, the reciprocal of ther resistances add:

or

The equivalent resistance will always be less than the smallest resistor in the circuit, so the equivalent resistance will always decrease as more resistors are added. A decrease in the resistance means that the current will increase.
