An alien from outer space was just captured. Scientists take turns examining the creature. At a press conference, one of the scientists reports that the alien can hear frequencies between 10,000 and 30,000 Hz. How does the alien's ability to detect sound compare to a human being's ability?
A) The alien and humans detect the same frequencies.
B) Humans can detect higher frequencies than the alien.
C) The alien can detect higher frequencies, but its hearing is not as acute at lower frequencies.
D) Humans can detect higher frequencies; however, the alien detects lower frequencies better than humans.
E) Humans can detect both lower and higher frequencies than this alien.

Humans typically hear frequencies from about 20 Hz to 20,000 Hz. The alien's hearing range starts at a higher frequency than humans can detect (10,000 Hz) and extends beyond the upper limit of human hearing (30,000 Hz). This means the alien can hear higher frequencies than humans but cannot hear the lower frequencies that humans can.
