Final answer:
The low-frequency vibration sensitivity and sensitivity to slip are both low.
Step-by-step explanation:
The low-frequency vibration sensitivity refers to how sensitive the body is to vibrations at low frequencies. The sensitivity to slip refers to the body's ability to detect and respond to slipping or sliding movements. In both cases, a lower value indicates a higher sensitivity, so the answer is 2) Low for both low-frequency vibration sensitivity and sensitivity to slip.
The term sensitivity to slip could refer to the 'can't let go' current phenomenon where a person is unable to release their grip from an electrified object due to muscle contractions caused by electrical current passing through the body. This effect is also frequency-dependent and tends to be more pronounced at certain frequencies.
