A security guard acting as a witness in a trial testified that he observed 20 cars in a parking lot. Of the cars he observed, 12 were convertibles, 15 had out of state plates, and 5 were convertibles with out of state plates. The witness —————- (is, may not be or is not) telling the truth because the information —————- (is insufficient to make conclusions, confirms he searched 20 cars, implies he searched less than 20 cars, implies he observed more than 20 cars)
