Your task is to classify the state of the entity into three classes: 1) not exist, 2) unknown location and 3) known location. "not exist" means the entity doesn't exist in that state anymore. "unknown location" means the entity exists in that state but location is unknown. "known location" means the entity exists and location is known.

Ex Input:
"process paragraph : : Magma is formed when rock melts inside the Earth's crust. Magma rises. Collects inside magma chambers underneath a volcano. Pressure builds in the magma chambers as they fill. Gain energy for eruption. Some of the energy is converted into seismic activity (earthquakes). If the magma building in the volcano is thick and sticky it will trap gases. Results in an explosive eruption when the pressure becomes too intense. If the magma is thin and runs. The magma results in a low-pressure, slow-moving flow of magma instead of a violent eruption. ", "event : Magma rises.", "entity : volcano"

Ex Output:
unknown location

Ex Input:
"process paragraph : : Sound waves enter your outer ear. Travel through ear canal to your ear drum. Eardrum vibrates with the incoming sound. Send the vibrations to three tiny bones in your middle ear. Bones in your middle ear amplify the vibrations. Send them to your inner ear. The vibrations activate tiny hair cells in your inner ear. The hair cells release neurochemical messengers. Your auditory nerve carries the message to your brain. The brain translates the message so you can understand. ", "event : Travel through ear canal to your ear drum.", "entity : neurochemical messengers"

Ex Output:
unknown location

Ex Input:
"process paragraph : : Living things have carbon in them. Living things die. The remains of living things eventually become buried underground. More physical pressure is put on the remains of living things as they become further underground. This carbon-based mixture stays underground for a long time. Humans discover this carbon-based mixture. This carbon-based mixture is brought up to the earth's surface. The recently discovered fossil fuel is burned. Burning releases the energy that has been stored in the fossil fuel. The energy can be used to generate power. ", "event : Living things die.", "entity : living things ; remains of living things"

Ex Output:
unknown location
