What is the meaning of the term "ford"?

The term "ford" is defined as the act of crossing a stream or river, particularly in a shallow area where people or vehicles can pass. This definition captures the essence of the word, which often implies a method of traversing water that is not deep enough to require a boat or significant effort. The imagery of fording a stream evokes the idea of navigating through a natural obstacle, making it a practical term in both literal and metaphorical contexts.

The other options do not align with the core meaning of "ford." An opening made forcibly refers to a different type of action, one that involves creating a gap or entry, rather than crossing a body of water. A bar used to resist compression is more related to construction or engineering terms and is unrelated to crossing water. Drawing back with fear or pain pertains to emotional or physical reactions, which again deviates from the concept of crossing a stream or river. Thus, the correct choice precisely reflects the action associated with fording.
