a puddle of dark liquid under a car indicates a leak in the oil or transmission fluid. another warning sign of car trouble is uneven wear on the treads. if the outer edge of the tire tread wears out before the center, the tire is under-inflated. the most significant early warning signal, however, is less and less mileage per gallon. lower fuel economy is caused by a variety of problems ranging from a clogged air filter to ignition or carburetor trouble.
which sentence best expresses the implied main idea of the paragraph above?
○ several warning signs can indicate car problems.
○ the most significant warning signal of a car problem is getting lower mileage per gallon of gas.
○ various problems may cause a cars fuel economy to decrease.
○ a puddle of dark liquid under a car is a sign that a car has an oil or transmission fluid leak.
