A; occasionally resistors short out especially at hi frequency hi voltage due to external contamination. But usually resistors open up or change to a hi value due to power overstress
If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.
Film resistors have lower noise than carbon resistors.
What would the measured ohms be for two 100 ohm resistors wired in series? Two 100 ohm resistors wired in series measure 200 ohms.
I observe that the total effective resistance of several resistors in series is the sum of the individual resistance values of the individual resistors.
It depends upon the connection of the resistors, if the resistors are connected in parallel then the voltage is same where as in case of resistors connected in series the voltage is different across different resistors.

most of the resistors commonly used are carbon resistors
This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.

Film resistors have lower noise than carbon resistors.
The short circuited path is the one which doesn't have any distributed elements(i.e., resistors, inductors,etc...). So the highly short circuited means only 'the connecting wire' is present in the circuit.
What would the measured ohms be for two 100 ohm resistors wired in series? Two 100 ohm resistors wired in series measure 200 ohms.
Both resistors will have the voltage of the battery.
Resistors are wired in series when they are connected in a line. The current flows through the resistors one after the other.
