Задание №23701 ЕГЭ по Английскому языку

A professor's linguistic lesson

During a lecture, a professor sought to emphasize the concept of negation once again. "The                          (ONE) example is English," he stated. "In English, a double negative transforms into a positive. However, in certain languages like Russian, a double negative remains negative." He paused momentarily before continuing, "Interestingly, there                          (NOT BE) a language where a double positive results in a negative." A voice from the back of the room interjected, "Yeah, right."
