Like every Slayer before her, she was chosen and informed of her destiny when she was 15 years old. Her mother is unaware of her daughter's powers and responsibilities until Buffy is forced to tell her at the end of the second season of the television series. Although Joyce is shocked at this revelation, she recovers quickly and remains a source of stability for Buffy and Buffy's small circle of friends who assist her, dubbed the Scooby Gang. Eventually Joyce is able to take Buffy's dangerous demon-fighting in stride and even become proud and respectful of her daughter's abilities. Her natural death from an illness in the fifth season forces Buffy to face becoming an adult.

Example Input: passage: While they take the same form, the viscosity grades for gear oils are on a different scale than the viscosity grades for an engine oil. The viscometrics for gear oils are standardized in SAE J306. Multigrade gear oils are becoming more common; while gear oil does not reach the temperatures of motor oil, it does warm up appreciably as the car is driven, due mostly to shear friction (with a small amount of heat conduction through the bellhousing from the engine block).
 question: is gear oil the same as motor oil?
Example Output:
No
