Choose the word nearest in meaning to the given word: OSCILLATE

Key meaning: 'Oscillate' means to move back and forth repeatedly.

• Why 'swing' is the best choice: both words describe a regular or pendulum-like back-and-forth motion.

• Why 'tremble' is less suitable: it means to shake or quiver, often slightly or involuntarily, and does not specifically imply a regular back-and-forth movement.

• Why 'hang' is incorrect: it means to be suspended or dangle, not to move back and forth.

• Why 'freeze' is incorrect: it means to become motionless, which is the opposite of oscillating movement.
