<human>:  How can I fix a clogged sink drain?
<bot>: Begin by trying to clear the clog using a plunger. Fill the sink with enough water to cover the plunger and begin plunging up and down and around the drain opening. If this doesn't work, try using a plumber’s snake. Put the snake into the drain and carefully turn it until you feel it catching on the clog. Push it forward, then slowly pull it back up. Repeat this process. If these methods do not work, you may need to disconnect the plumbing beneath the sink and clear the clog with a pipe cleaner or drain auger.
